Summary:
Added a button to the iOS Red Box to enable copying of the error and stack trace to the clipboard to make it easier to paste the error and stack into bug reports or other text windows. Clicking the Copy button on the bottom of the RedBox screen or pressing Cmd-Option-C keyboard shortcut in the simulator will copy the full stack trace as text to the iOS pasteboard and when in the simulator you can then hit Command-C to get the text to the Mac's pasteboard for pasting in your favorite reporting/tracking app.
No tests for this change - I don't see any tests to extend for the RCTRedBoxWindow class. No impact on APIs or core React Native functionality. I validated it by running test React Native apps with red box errors and both hitting the copy button or using the command key shortcut in the emulator to get the text of the stack to the iOS pasteboard.

Summary:
Previously, only Text and Image could be nested within Text. Now, any
view can be nested within Text. One restriction of this feature is
that developers must give inline views a width and a height via
the style prop.
Previously, inline Images were supported by using iOS's built-in support
for rendering images with an NSAttributedString via NSTextAttachment.
However, NSAttributedString doesn't support rendering arbitrary views.
This change adds support for nesting views within Text by creating one
NSTextAttachment per inline view. The NSTextAttachments act as placeholders.
They are set to be the size of the corresponding view. After the text is
laid out, we query the text system to find out where it has positioned each
NSTextAttachment. We then position the views to be at those locations.
This commit also contains a change in `RCTShadowText.m`
`_setParagraphStyleOnAttributedString:heightOfTallestSubview:`. It now only sets
`lineHeight`, `textAlign`, and `writingDirection` when they've actua

Summary:
The `EmitterSubscription.remove()` method was previously calling `this.subscriber.removeSubscription(this)` directly, bypassing the mechanism in `NativeEventEmitter` that keeps track of the number of subscriptions.
This meant that native event modules (subclasses of `RCTEventEmitter`) would keep sending events even after all the listeners had been removed. This wasn't a huge overhead, since these modules are singletons and only send one message over the bridge per event, regardless of the number of listeners, but it's still undesirable.
This fixes the problem by routing the `EmitterSubscription.remove()` method through the `EventEmitter` so that `NativeEventEmitter` can apply the additional native calls.
I've also improved the architecture so that each `NativeEventEmitter` uses its own `EventEmitter`, but they currently all still share the same `EventSubscriptionVendor` so that legacy code which registers events via `RCTDeviceEventEmitter` still works.

Summary:
There's an edge case in the `RefreshControl` which causes it to show as refreshing when the state is set to false. When the component is initialized with `refreshing` set to `true` on initial render but set to `false` before `layoutSubviews` is called, it will call `beginRefresh` and ignore its state. That's because `layoutSubviews` never checks if `_currentRefreshingState` is in fact still `true`, it merely assumes it is.
This is fixed by simply doing a check for `_currentRefreshingState` before entering `beginRefresh` from `layoutSubviews`.

This diff fixes it by making sure two cancel events cannot have the same coalescing key.

Summary:
This is a solution for the problem I raised in https://www.facebook.com/groups/react.native.community/permalink/768218933313687/
I've added a new native base class, `RCTEventEmitter` as well as an equivalent JS class/module `NativeEventEmitter` (RCTEventEmitter.js and EventEmitter.js were taken already).
Instead of arbitrary modules sending events via `bridge.eventDispatcher`, the idea is that any module that sends events should now subclass `RCTEventEmitter`, and provide an equivalent JS module that subclasses `NativeEventEmitter`.
JS code that wants to observe the events should now observe it via the specific JS module rather than via `RCTDeviceEventEmitter` directly. e.g. to observer a keyboard event, instead of writing:
const RCTDeviceEventEmitter = require('RCTDeviceEventEmitter');
RCTDeviceEventEmitter.addListener('keyboardWillShow', (event) => { ... });
You'd now write:
const Keyboard = require('Keyboard');
Keyboard.addListener('keyboardWillShow', (event) => { ... });
Within a component, you can also use the `Subscribable.Mixin` as you would previously, but instead of:
this.addListenerOn(RCTDeviceEventEmitter, 'keyboardWillShow', ...);
Write:
this.addListenerOn(Keyboard, 'keyboardWillShow', ...);
This approach allows the native `RCTKeyboardObserver` module to be created lazily the first time a listener is added, and to stop sending events when the last listener is removed. It also allows us to validate that the event strings being observed and omitted match the supported events for that module.
As a proof-of-concept, I've converted the `RCTStatusBarManager` and `RCTKeyboardObserver` modules to use the new system. I'll convert the rest in a follow up diff.
For now, the new `NativeEventEmitter` JS module wraps the `RCTDeviceEventEmitter` JS module, and just uses the native `RCTEventEmitter` module for bookkeeping. This allows for full backwards compatibility (code that is observing the event via `RCTDeviceEventEmitter` instead of the specific module will still work as expected, albeit with a warning). Once all legacy calls have been removed, this could be refactored to something more elegant internally, whilst maintaining the same public interface.
Note: currently, all device events still share a single global namespace, since they're really all registered on the same emitter instance internally. We should move away from that as soon as possible because it's not intuitive and will likely lead to strange bugs if people add generic events such as "onChange" or "onError" to their modules (which is common practice for components, where it's not a problem).

Summary:
Previously we had an issue where we would clip visible views during an animation, like swiping back a VC.
The root cause was mismatch between a view's frame and what is visible on screen. This happens because during an animation the frame (and other properties) of the animated view has final values, even that it's not yet rendered at that position.
This diff fixes this issue by not looking for a clippingView above the react root view, since the animation for VC transitions happens at view higher above the root view.

Previously, the back swipe navigation gesture would be enabled when the navigation bar is shown and disabled when the navigation bar is hidden.
This change enables developers to control the back swipe gesture independently of the visibility of the navigation bar. An example use case would be that an app wants to render a custom navigation bar so it sets `navigationBarHidden` to true and it wants to enable the back swipe gesture so it sets `interactivePopGestureEnabled` to true.

Summary:
Modules which call JS methods directly, or use `sendDeviceEventWithName:`, can trigger effects in JS without ever being referenced from the JS code. This breaks some assumptions in my earlier diff about when modules can be lazily loaded.
Pending a better solution, I've put explicit `init` methods in these modules to ensure they are eagerly initialized (the downside to this is that they'll still be initialized even if they are never used).

Summary:
Previously, if a module implemented `setBridge:` we assumed that it needs to be initialised on the main thread. This assumption was not really warranted however, and it was a barrier to deferring module initialization.
This diff tweaks the rules so that only modules that override `init` or `constantsToExport**` are assumed to require main thread initialization, and others can be created lazily when they are first used.
WARNING: this will be a breaking change to any 3rd party modules that are assuming `setBridge:` is called on the main thread. Those modules should be rewritten to move any code that requires the main thread into `init` or `constantsToExport` instead.
`**` We will also be examining whether `constantsToExport` can be done lazily, but for now any module that uses it will still be created eagerly when the bridge starts up.

Summary:
transformMatrix only worked on iOS and there is an equivalent API that (mostly)
works cross platform.
decomposedMatrix could technically be passed on Android but it wasn't document and explicitly flagged as not working.
My goal is to deprecate both uses and then the only supported API is the `transform: [{ matrix: ... }]` form.
The only difference is that on Android the matrix gets decomposed.
Currently there is some special cased magic that renames transform -> transformMatrix or decomposedMatrix depending on platform.
https://github.com/facebook/react/blob/master/src/renderers/native/ReactNative/ReactNativeAttributePayload.js#L50
Therefore I'm adding an alias for both native platforms called just "transform".
Next I'll swap over the JS to always target the name "transform". The only difference is how the value is marshalled over the bridge in processTransform.
To do this, I have to clean up a few callers. Mostly that's just swapping to the new API.
For buildInterpolator this is a bit trickier but this fixes it for all our use cases (which is only the Navigator in AdsManager).

Summary:
Now that we support initializing the bridge off the main thread, some of the assumptions in the bridge setup process are no longer safe.
In particular we were assuming that the JS executor and injected modules could always be synchronously initialized within bridge init, but that is only safe if those modules don't need to be set up on the main thread.
The setup for those modules was sync-dispatching to the main thread if bridge init happened on a background thread, and this lead to a deadlock under certain circumstances.

Summary:**Motivation:** In my app, I'm using a WebView that loads content from my mobile site. What I want to do is when a user presses a link on the loaded page, I want to stop the WebView's request, hijack the URL and open the URL in a new WebView, pushed to the top of the navigator stack. To me, this gives the overall app a more native feel, instead of implementing a rudimentary navbar on the main WebView to go back.
**Attempted Workarounds:** I've attempted to get similar functionality by capturing the onNavigationStateChange event in the WebView, and then within calling goBack + pushing the new view to the navigator stack. From a functionality standpoint, this works. However, from a UI standpoint, the user can clearly see the webview change states to a new page + go back before having the new view pushed on top of their nav stack.

Summary:Hey,
I have been going through some UIAlert related issues in the repo trying to fix them, and one of the steps to start reproducing them was to put `Alert.alert()` call right inside `componentDidMount`.
However, I've started noticing strange bugs as long as I didn't set 1second timeout.
Started digging in deeper, and I've noticed the `UIAlert` gets attached to the `RCTWindow()` mainViewController.
However - since RCTDevLoadingView adds a `keyWindow`, that is the window that will be returned at the time of the call and the window `UIAlert` will be attached to.
To visualise that better - you can take a look at these two frames when app is being loaded:

This diff fixes this behavior by wrapping the content in another view. That makes the modal's wrapping VC's view resize just once when it's initially created. (Resize for the wrapping VC's view happened previously when the modal's content resized, which got us in the bad state.)

Summary:To use a ScrollView and RefreshControl with a translucent navigation bar you have to set the top inset to the height of that bar, allowing the content to scroll underneath. After changes to RCTRefreshControl in **v0.22**, `endRefreshing` always animates the offset to 0, hiding content behind the navigation bar. What you'd expect on iOS is for it to return to the bottom of the bar.
**Test plan**
To see this in action, refer to the UIExplorerApp. In RefreshControlExample.js if you set the ScrollView's `contentInset={{top: 100}}` you'll see the refresh control UI is where you'd expect, and after refresh the list returns to the correct position.

Summary:All UIManager operations that affect the view hierarchy are executed via the `addUIBlock:` method, which queues them up to be executed after layout has been completed on the shadow queue.
One of the most expensive view operations is view creation, but since this doesn't actually depend on layout, there's no reason to delay it until the shadow operations have finished.
This diff modifies the `createView` method to dispatch view creation directly to the main thread instead of adding it to the UIBlock queue. This seems to result a measurable improvement in TTI.

Summary:On iOS, `WebView` will get stuck when the first request fails to load. The most common case where this could happen is when a user has limited or no connectivity.
Here's a repo with a sample app that demonstrates the problem and this fix: [https://github.com/jballer/react-native-webview-reload-example](https://github.com/jballer/react-native-webview-reload-example).
**Attempted workarounds**
- `WebView.reload()` fails internally because the `UIWebView`'s `currentRequest` doesn't have its `URL` set
- Setting `WebView.source.uri` won't do anything; the JS value value is unchanged and therefore doesn't cross the native bridge.
- Unmounting and remounting the `WebView` component would lose history and context if an error occurs on a request that's not the first request.
**Test plan (manual testing)**
1. Disable network connection
1. Relaunch application or reload JS
1. Enable network connection
1. Tap "reload" button
1. Observe whether page reloads

Summary:Turns our using the same coalescing key until a person removes all fingers off screen is not ideal.
It doesn't work in a case where the first finger starts moving on screen and then a second finger joins it later (almost any pinch gesture),
since we would try to coalesce move events from the start when only one finger was touching screen with events where two fingers were moving on screen.
That doesn't work and results in a crash.
I've changed the logic for generating the coalescing key in order to prevent this.
We no longer have a single key for a single gesture, but we change the key each time amount of fingers increases ("touchStart") or decreases ("touchEnd").

Summary:D3092867 / 1d3db4c5dc caused deadlock when chrome debugging was turned on, so it was reverted as D3128586 / 144dc30661.
The reason: I was calling `[_bridge dispatchBlock:^{ [self flushEventsQueue]; } queue:RCTJSThread];` from main thread and expecting it will `dispatch_async` to another,
since a held lock was being accessed the dispatched block and was released after the dispatch.
Turns out `RCTWebSocketExecutor` (which is used when chrome debugger is turned on) executes all blocks dispatched this way to `RCTJSThread` synchronously on the main thread.
This resulted in a deadlock. The "dispatched" block was trying to acquired lock which held by the same thread in the dispatching phase.
A fix for this is pretty simple. We will release the lock before dispatching the block.
However it's not super straightforward to see this won't introduce some race condition in a case with two threads where we would end up with events not being processed.
My thinking why that shouldn't happen goes like this: We could get in a bad state if `flushEventsQueue` would run on JS thread while `sendEvent:` is running on MT.
(I don't have a specific example how, maybe it's not possible. However when I show this case is safe we know we are good.)
The way how locking is setup in this diff the only possible scenario where these two threads would execute in these methods concurrently is JS holding the lock and MT going to enqueue another block on JS thread (since that's outside of "locked" zone).
But this scenarion can never happen, since if MT is about to enqueue the block on JS thread it means there cannot be a not yet fully executed block on JS thread.
Therefore nothing bad can happen.
So this diff brings back the reverted diff and adds to it the fix for the deadlock.

Summary:If you're working on an app that needs to support landscape, reloading the app causes the iPhone simulator to reset its orientation to portrait every time the `RCTDevLoadingView` shows up. This is because it sets the root VC to `RCTModalHostViewController`, which currently supports only portrait orientations on iPhone. Changing the root view to a vanilla `UIViewController` fixes the issue.
**Steps to Reproduce**
1. Create a blank RN project: `react-native init RNTest`
2. Open it up and run it.
3. Rotate to landscape `Cmd+Right Arrow`.
4. Reload by pressing `Cmd+R`.
**Expected**
The simulator stays in landscape mode.
**Actual**
The simulator goes back to portrait.

Summary:A need for sending a scroll events outside of scrollview made D3092854 a bit clunky. This diff kinda fixes it by tightening up emitting of fake scroll events just to the only usecase we have right now.
Why not just simply construct the event in `RCTNavigator`, so we can drop the code from `RCTScrollView` altogether?
`RCTScrollEvent` is private to `RCTScrollView`, and that's good. We don't want anyone have an ability to make up scroll events. Even this existing functionality should be sunset one day when we better integrate with native gesture recognizers.
Depends on D3092867.

Summary:Previously, (mostly touch and scroll) event handling on iOS worked in a hybrid way:
* All incoming coalesce-able events would be pooled and retrieved by js thread in the beginning of its frame (all of this happens on js thread)
* Any non-coalesce-able event would be immediately dispatched on a js thread (triggered from main thread), and if there would be pooled coalesce-able events they would be immediately dispatched at first too.
This behavior has a subtle race condition, where two events are produced (on MT) in one order and received in js in different order.
See https://github.com/facebook/react-native/issues/5246#issuecomment-198326673 for further explanation of this case.
The new event handling is (afaik) what Android already does. When an event comes we add it into a pool of events and dispatch a block on js thread to inform js there are events to be processed. We keep track of whether we did so, so there is at most one of these blocks waiting to be processed. When the block is executed js will process all events that are in pool at that time (NOT at time of enqueuing the block).
This creates a single way of processing events and makes it impossible to process them in different order in js.
The tricky part was making sure we don't coalesce events across gestures/different scrolls. Before this was achieved by knowing that gestures and scrolls start/end with non-coalesce-able event, so the pool never contained events that shouldn't be coalesced together. That "assumption" doesn't hold now.
I've re-added `coalescingKey` and made touch and scroll events use it to prevent coalescing events of the same type that should remain separate in previous diffs (see dependencies).
On top of it it decreases latency in events processing in case where we get only coalesce-able events. Previously these would be processed at begging of the next js frame, even when js would be free and could process them sooner. This delay is done, since they would get processed as soon as the enqueued block would run.
To illustrate this improvement let's look at these two systraces.

Summary:We found that moving the preloaded modules to the startup section of the RAM Bundle improves TTI quite a bit by saving lots of through the bridge calls and injecting multiple modules at once on JSC. However, doing this on a non hacky way required a lot of work. The main changes this diff does are:
- Add to `BundleBase` additional bundling options. This options are fetched based on the entry file we're building by invoking a module that exports a function (`getBundleOptionsModulePath`).
- Implement `BundleOptions` module to include the `numPreloadedModules` attribute as a bundle additional option. This value is computed by getting the dependencies the entry file has and looking for the first module that exports a module we don't want to preload. The `numPreloadedModules` attribute is then used to decide where to splice the array of modules.
- Additional kung fu to make sure sourcemaps work for both preloaded and non preloaded modules.
