Explain the **motivation** for making this change. What existing problem does the pull request solve?
See https://github.com/facebook/react-native/issues/10506. A native `NSError` with `NSUnderlyingErrorKey` set causes a JSON stringify error from the websocket dispatcher if remote debugging is enabled.
**Test plan (required)**
I'm not familiar with the react native testing framework. Happy to add a test for this if someone can point me to where this part of the codebase is exercised :)
I did some spot checks with nil user dictionaries and nil underlying errors here. The case that this solves is testable using https://github.com/superseriouscompany/react-native-error-repro, specifically:
```objective-c
NSError *underlyingError = [NSError errorWithDomain:@"underlyingDomain" code:421 userInfo:nil];
NSError *err = [NSError errorWithDomain:@"domain" code:68 userInfo:@{@"NSUnderlyingError": underlyingError}];
reject(@"foo", @"bar", err);

Summary:
Packager can take a long time to load and the progress is usually displayed in another window (Terminal). I'm adding support for showing a UI inside React Native app for packager's progress when loading a bundle.
This is how it will work:
1. React Native sends request to packager with `Accept: multipart/mixed` header.
2. Packager will detect that header to detect that client supports progress events and will reply with `Content-Type: multipart/mixed`.
3. While building the bundle it will emit chunks with small metadata (like `{progress: 0.3}`). In the end it will send the last chunk with the content of the bundle.
4. RN runtime will be receiving the events, for each progress event it will update the UI. The last chunk will be the actual bundle which will end the download process.
This workflow is totally backwards-compatible -- normally RN doesn't set the `Accept` header.

Summary:
This fixes measuring of items in the main axis of a container. Previously items were in a lot of cases measured with UNSPECIFIED instead of AT_MOST. This was to support scrolling containers. The correct way to handle scrolling containers is to instead provide them with their own overflow value to activate this behavior. This is also similar to how the web works.
This is a breaking change. Most of your layouts will continue to function as before however some of them might not. Typically this is due to having a `flex: 1` style where it is currently a no-op due to being measured with an undefined size but after this change it may collapse your component to take zero size due to the implicit `flexBasis: 0` now being correctly treated. Removing the bad `flex: 1` style or changing it to `flexGrow: 1` should solve most if not all layout issues your see after this diff.

Currently we use AT_MOST to measure in the cross axis but not in the main axis. This was done to enable scrolling containers where children are not constraint in the main axis by their parent. This caused problems for non-scrolling containers though as it meant that their children cannot be measured correctly in the main axis. Introducing `overflow:scroll` fixes this.

Summary:
Include CSSLayout headers in the same way as other project headers, ie `#import <CSSLayout/CSSLayout.h>` becomes `#import "CSSLayout.h"`. CSSLayout is not a framework or system dependency, so shouldn't (AFAIK) be included with angle brackets. Doing so breaks framework builds, such as when RN is used as a pod in a swift project.
In combination with https://github.com/facebook/css-layout/pull/217 this fixes https://github.com/facebook/react-native/issues/9014 (specifically swift cocoapods projects). There is then no need for a separate CSSLayout pod subspec.
Tests run on the RN project in isolation (with changes inside `CSSLayout` itself also applied) and against a dummy swift project with RN included as a pod.
NB: This effectively reverts https://github.com/facebook/react-native/pull/9015 and may break non-swift cocoapods projects unless https://github.com/facebook/css-layout/pull/217 is merged and synced first.

Summary:
**Motivation:** We have a project that dynamically changes classes in runtime. This component is initialised within the React Native context. Therefor `RCTBatchedBridge` copies the classes before changes are made to them. While React Native is running, changes are made to the classes dynamically. When the project reloads the `RCTBatchedBridge`, it now has an invalid list of classes containing trash pointers. This causes the project to crash on https://github.com/facebook/react-native/blob/master/React/Base/RCTBatchedBridge.m#L288 with EXC_BAD_ACCESS in the DEBUG-mode.
**Solution:** Copy the class list on each reload to get the current state. Since this is only a DEBUG-feature the overhead of this should not be a major issue.

Summary:
This uses `[UIImage imageNamed:]` to load local assets that are bundled using `require('../image/path.png')` and makes sure it is done synchronously on the main queue to prevent images from flickering. This improves user experience a lot when using large local images and prevents icon flickers to match the behaviour of most native apps.
This adds to methods to the ImageLoader protocol, one to tell if the image loader must be executed on the url cache queue and one to tell if the result of the image loader should be cached. I then use these to make the LocalImageLoader bypass the url cache queue and avoid caching images twice.
Note that this doesn't affect debug builds since images are loaded from the packager.
I'm not sure if we want to still support async loading of local images as I'm not sure how much of a perf difference this will make. Maybe someone at fb can benchmark this see how it affects your apps but there wasn't a noticeable one in mine. Also I only enabled this for loading png and jpg im

Summary:
This diff refactors the view update process into two stages:
1. The `reactSubviews` array is set, whose order matches the order of the JS components and shadowView components, as specified by the UIManager.
2. The `didUpdateReactSubviews` method is called, which actually inserts the reactSubviews into the view hierarchy.
This simplifies a lot of the hacks we had for special-case treatment of subviews: In many cases we don't want to actually insert `reactSubviews` into the parentView, and we had a bunch of component-specific solutions for that (typically overriding all of the reactSubviews methods to store views in an array). Now, we can simply override the `didUpdateReactSubviews` method for those views to do nothing, or do something different.

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).

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:
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: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: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:
This is a final diff in the stack, which makes us not send a bazillion events to js after it's been busy while an user dragged his finger on a screen (resulting in ~two events per frame).
I made "touchMove" event to be coalescable, which makes us not send anything while dragging (since this makes both scroll events and touch move events coalesced and not being send until either next js frame or the next different touch event occurs).
This change is far from perfect. The event name is a hard coded string and the coalescing works with some (reasonable) assumptions on internal structure of these touch events. Which may or may not be really true. It would be great if someone could comment on these.
I'm thinking about making the touches more strongly typed. Any thoughts on this?

Summary:
This diff finally makes touch events to be emitted to js from the same object as scroll events. Thanks to changes in previous diffs this means the js will now process them in the right order.
This diff on its own would cause us to send events to js on every frame while dragging a finger on the screen. This is something we tried to avoid with event coalescing in the past, and gets fixed in the following diff D2884595.

**This diff is part of a larger stack. This is a high level overview about what’s going on here.**
This stack of diffs fixes an issue where scroll events and touch events wouldn’t be processed in the correct order on js side.
Current state of world:
* touch events are send to js immediately when they happen (this makes js respond to touches as soon as possible)
* scroll events are buffered, coalesced and send at the beginning of each js frame (coalescing helps in a case where js is busy processing for several native frames and would get all scroll event for that period afterwards)
How did I change this?
1. I’ve made touch events go through the same class every other event (scroll events included) go, RCTEventDispatcher. This gives us a single place to handle all events.
2. I’ve changed RCTEventDispatcher to flush all buffered events every time it gets a touch event before dispatching the touch. This fixes the original ordering issue.
3. I’ve made “touchMove” behave the same way as scroll events do - they are buffered and coalesced. Since “touchMove” events are fired as often as scroll events (while you drag your finger around), doing only 2. would bring back the issue buffering was fixing.
All of this together effectively still keeps the order of events right, avoids overloading js in the important case we care about. The only downside is an increased latency for “touchMove” events, since they are to longer send to js immediately.
(Even better solution would be changing the native->js event passing system to be pull based instead of push based. That way js would always request touches that has happened since the last time it has asked, which would make it get them as soon as it’s possible to process them and native could do coalescing at that point.
However this change has a much bigger scope, so I’m going with this stack of diffs for now.)

I think this makes sense because there is no unified arguments format for all events and and the called js method (`moduleDotMethod`) is already event specific.
This way touch events and scroll events can result in calling a completely different js function with a completely different arguments (what they indeed currently do).
