Summary:
This fixes [#15801](https://github.com/facebook/react-native/issues/15801)
We ran into a strange crash on iOS (debug only). After removing the clutter I was able to reproduce it in a tiny app. You can check it out [here.](https://github.com/simonracz/textinput_stress)
The UI in JS and native are not always in sync (which is okay). Due to this, a native view might call back into JS, which is no longer present in the shadow view hierarchy there. I think this should be also okay.
TextInput in some cases calls into [setIntrinsicContentView](6d67e2dbbc/React/Modules/RCTUIManager.m (L382)), where it triggers an overly enthusiastic `NSAssert` and crashes the app.
Check out [textinput_stress](https://github.com/simonracz/textinput_stress)
Rotate the simulator a few times to see the crash or the lack of crash.

Summary:
This is required for D5874536, wherein I'll be introducing direction-aware props for borders.
When a view's border changes due to a direction update, only the frames of its children update. Therefore, only the children `UIView`s get a chance to be re-rendered. This is incorrect because the view that's had its borders changed also needs to re-render. So, I keep a track of the layout direction in a property on all shadow views. Then, when I update that prop within `applyLayoutNode`, I push shadow views into the `viewsWithNewFrames` set.

Summary:
Basic implementation of the proposal in #15271
Note that this should not affect facebook internally since they are not using OSS releases.
Points to consider:
- How strict should the version match be, right now I just match exact versions.
- Wasn't able to use haste for ReactNativeVersion because I was getting duplicate module provider caused by the template file in scripts/versiontemplates. I tried adding the scripts folder to modulePathIgnorePatterns in package.json but that didn't help.
- Redscreen vs. warning, I think warning is useless because if the app crashes you won't have time to see the warning.
- Should the check and native modules be __DEV__ only?
**Test plan**
Tested that it works when version match and that it redscreens when versions don't before getting other errors on Android and iOS.

Summary:
This issue has been open for a really long time, but I'm pretty sure this is the line that needed to change:
https://github.com/facebook/react-native/issues/1831
What was happening here is that `CGRectIsEmpty` returns true when either height or width is zero. With the current logic, one of those would always be zero when the parent was rendered off screen. This ensures that there the intersection be of CGSizeZero for the view to actually be clipped.
That being said, there seems to be something more complex going on here that I'm not understanding? I would think that you'd simply want to check if the child view's frame is within the bounds of the parent at all. If it was, then don't clip it. If I'm in the wrong, could someone explain this a bit more? If so, I'll fix this issue.
Using this [repository](https://github.com/jcharlet/react_native_listview_bug), this one line change fixes the issue and still clips cells as they are scrolled off screen.

Summary:
Content offset was broken because on initial render contentSize is {0,0} so any positive offset is lost. Also inset top/bottom and left/right were inversed �, this led to bad initial scrolling offset when using contentInset. This fixes it by making sure contentSize is actually measured (not {0,0}. I guess it's possible that the content is ACTUALLY {0,0} but in that case I don't think it really matters).
**Test plan**
Tested that a scrollview has proper scroll position when specifying contentOffset. Also tested that it works well with contentInset.
```js
<ScrollView contentOffset={{y: 100}}>

Summary:
> The property contentInset can change the maximum and minimum values of the content offset to allow scrolling outside of the scrollable area. Its type is UIEdgeInsets, which consists of 4 numbers: {top, left, bottom, right}. When you introduce an inset, you change the range of the content offset. For example, setting the content inset to have a value of 10 for its top value allows the content offset’s y value to reach -10. This introduces padding around the scrollable area.

Summary:
This shows progress for the download of the JS bundle (different from the packager transform progress that we show already). This is useful especially when loading the JS bundle from a remote source or when developing on device (on simulator + localhost it pretty much just downloads instantly). This will be nice for the expo client since all bundles are loaded over the network and can take several seconds to load.
This depends on https://github.com/facebook/metro-bundler/pull/28 to work but won't crash or anything without it, it just won't show the progress percentage.

Summary:
We've simplified a lot of the conditions for eager of the module init so now we can introduce a final switch to allow modules to opt-out (and in the future opt-in if they still require the behaviour).
We now require you to be explicit about the intended behaviour and implement the `+ (BOOL)requiresMainQueueSetup` method on your module. When you return YES from this method, it tells the bridge the module needs to be created on the main thread (and to avoid deadlocks, we do so eagerly during bridge startup). When you return NO, the native module will be initialised when it's first accessed from JS.
The current behaviour is maintained but a warning is emitted until the new API is adopted.

Summary:
In iOS11, Apple added a new layout feature called "Safe Areas" (this blog post talks a bit about it: https://www.bignerdranch.com/blog/wwdc-2017-large-titles-and-safe-area-layout-guides/).
UIScrollView is one component that is affected by this change in Apple's API. When the `contentInsetAdjustmentBehavior` is set to `automatic`, for example, it will adjust the insets (and override any manually set insets) automatically based on whether or not there's a UINavigationBar, a UITabBar, a visible status bar, etc on the screen. Frustratingly, Apple decided to default to `Automatic` for this behavior, which will cause any apps that set contentInset/contentContainerStyle padding to have their values offset by, at the very least, the size of the status bar, when they compile their app for iOS 11. Here's more information about this behavior: https://developer.apple.com/documentation/uikit/uiscrollview/2902261-contentinsetadjustmentbehavior?language=objc
Mostly, this is a really straightforward change -- it simply adds a new iOS-only prop to ScrollView that allows setting `contentInsetAdjustmentBehavior`. But I did decide to default the behavior to `never`, so that it mimics the behavior we've seen in iOS < 11. I think it's good to keep something as crucial as scrollview content insets non-magical, and also keep it behaving similarly between platforms.

Summary:
**Motivation:** This error can be a symptom of various other issues (see: an issue search for `__fbBatchedBridge is undefined`). I'm hoping to provide slightly more information about what might be going wrong and how to self-help.
**Test Plan:** Run some JS before the bridge has injected itself into the JS context. (sort of copping out here since the change is just to an error string literal.)

Summary:
This is the first PR from a series of PRs grabbou and me will make to add blob support to React Native. The next PR will include blob support for XMLHttpRequest.
I'd like to get this merged with minimal changes to preserve the attribution. My next PR can contain bigger changes.
Blobs are used to transfer binary data between server and client. Currently React Native lacks a way to deal with binary data. The only thing that comes close is uploading files through a URI.
Current workarounds to transfer binary data includes encoding and decoding them to base64 and and transferring them as string, which is not ideal, since it increases the payload size and the whole payload needs to be sent via the bridge every time changes are made.
The PR adds a way to deal with blobs via a new native module. The blob is constructed on the native side and the data never needs to pass through the bridge. Currently the only way to create a blob is to receive a blob from the server via websocket.
The PR is largely a direct port of https://github.com/silklabs/silk/tree/master/react-native-blobs by philikon into RN (with changes to integrate with RN), and attributed as such.
> **Note:** This is a breaking change for all people running iOS without CocoaPods. You will have to manually add `RCTBlob.xcodeproj` to your `Libraries` and then, add it to Build Phases. Just follow the process of manual linking. We'll also need to document this process in the release notes.

The websocket integration can be tested via a simple server,
```js
const fs = require('fs');
const http = require('http');
const WebSocketServer = require('ws').Server;
const wss = new WebSocketServer({
server: http.createServer().listen(7232),
});
wss.on('connection', (ws) => {
ws.on('message', (d) => {
console.log(d);
});
ws.send(fs.readFileSync('./some-file'));
});
```
Then on the client,
```js
var ws = new WebSocket('ws://localhost:7232');
ws.binaryType = 'blob';
ws.onerror = (error) => {
console.error(error);
};
ws.onmessage = (e) => {
console.log(e.data);
ws.send(e.data);
};
```

Summary:
In iOS11, Apple added a new layout feature called "Safe Areas" (this blog post talks a bit about it: https://www.bignerdranch.com/blog/wwdc-2017-large-titles-and-safe-area-layout-guides/).
UIScrollView is one component that is affected by this change in Apple's API. When the `contentInsetAdjustmentBehavior` is set to `automatic`, for example, it will adjust the insets (and override any manually set insets) automatically based on whether or not there's a UINavigationBar, a UITabBar, a visible status bar, etc on the screen. Frustratingly, Apple decided to default to `Automatic` for this behavior, which will cause any apps that set contentInset/contentContainerStyle padding to have their values offset by, at the very least, the size of the status bar, when they compile their app for iOS 11. Here's more information about this behavior: https://developer.apple.com/documentation/uikit/uiscrollview/2902261-contentinsetadjustmentbehavior?language=objc
Mostly, this is a really straightforward change -- it simply adds a new iOS-only prop to ScrollView that allows setting `contentInsetAdjustmentBehavior`. But I did decide to default the behavior to `never`, so that it mimics the behavior we've seen in iOS < 11. I think it's good to keep something as crucial as scrollview content insets non-magical, and also keep it behaving similarly between platforms.

Summary:
**Issue:**
Some fonts are defined with weights that don't match with the UIFontWeight constants.
**Example:**
UIFontWeightTraits for Roboto font
Light: -0.230
Thin: -0.365
Currently, the UIFontWeightTrait is always used if it != 0.0, and given the UIFontWeight constants for Light and Thin:
UIFontWeightThin -0.6
UIFontWeightLight -0.4
A style font weight of "300" or "200" will both resolve to Roboto-Thin as its weight -0.365 is closer to -0.4 (UIFontWeightLight) and -0.6 (UIFontWeightThin) than -0.230 (Roboto-Light).
**Proposed fix:**
When resolving `getWeightOfFont` try to match the name of weight to the name of the font first, and guess the font with UIFontWeightTrait as the fall back.
**Test Plan:**
Attempt to display Roboto at weights "200" and "300" and Roboto-Thin and Roboto-Light should be displayed correctly.

Summary:
When using the packager behind something like an http tunnel it is possible something else than JS is returned, in that case throw an error instead of trying to parse it.
This is useful for Expo since the packager runs behind ngrok. This allows to intercept that error and show a more meaningful error message based on the ngrok response.
**Test plan**
Tested by changing the packager to return text/html content type and validate that the error shows up properly.
Also tested that it works when multipart response is disabled.

Summary:
Surprisingly enough, even if semantically the code remains identical, layouting via autoresizing masks applies changes to subviews a bit earlier than iOS calls `layoutSubviews`.
This allows us to avoid situations where we already explicitly set calculated by Yoga frames and want to scroll to some subview, but actual layout have not done yet and internal views has wrong frames.

This PR fixes#15006 by removing all UI API calls from RCTScrollEvent.
`-[RCTScrollEvent arguments]` can now be called from a background thread.
The Main Thread Checker of Xcode 9 will not any longer produce runtime issues when calling this method.
1. create a React Native (version: this PR) project with a scroll view
2. open it in Xcode 9
3. launch it
4. scroll the scroll view
5. observe the runtime issues in Xcode. There should not contain "UI API called from background thread"-issues.

Summary:
It's very important in complex UIs to be able to apply alpha channel-based masks to arbitrary content. Common use cases include adding gradient masks at the top or bottom of scroll views, creating masked text effects, feathering images, and generally just masking views while still allowing transparency of those views.
The original motivation for creating this component stemmed from work on `react-navigation`. As I tried to mimic behavior in the native iOS header, I needed to be able to achieve the effect pictured here (this is a screenshot from a native iOS application):
![iOS native navbar animation](https://slack-imgs.com/?c=1&url=https%3A%2F%2Fd3vv6lp55qjaqc.cloudfront.net%2Fitems%2F0N3g1Q3H423P3m1c1z3E%2FScreen%2520Shot%25202017-07-06%2520at%252011.57.29%2520AM.png)
In this image, there are two masks:
- A mask on the back button chevron
- A gradient mask on the right button
In addition, the underlying view in the navigation bar is intended to be a UIBlurView. Thus, alpha masking is the only way to achieve this effect.
Behind the scenes, the `maskView` property on `UIView` is used. This is a shortcut to setting the mask on the CALayer directly.
This gives us the ability to mask any view with any other view. While building this component (and testing in the context of an Expo app), I was able to use a `GLView` (a view that renders an OpenGL context) to mask a `Video` component!
I chose to implement this only on iOS right now, as the Android implementation is a) significantly more complicated and b) will most likely not be as performant (especially when trying to mask more complex views).
Review the `<MaskedViewIOS>` section in the RNTester app, observe that views are masked appropriately.

Summary:
**Motivation**
This is a re-worked version of #14260, by shergin's suggestion.
For iOS, if you want to inherit from a native ViewManagers, your custom ViewManager will not automatically export the parents' props. So the only way to do this today, is to basically copy/paste the parent ViewManager-file, and add your own custom logic.
With this PR, this is made more extensible by exporting the `baseModuleName` (i.e. the iOS `superclass` of the ViewManager), and then using that value to re-establish the inheritance relationship in `requireNativeComponent`.
**Test plan**
I've run this with a test project, and it works fine there. But needs more testing.
Opened this PR as [per shergin's suggestion](https://github.com/facebook/react-native/pull/10946#issuecomment-311860545) though, so we can discuss approach.
**Discussion**
* Android already supports inheritance, so this change should be compatible with that. But, not every prop available on `UIManager.RCTView.NativeProps` is actually exported by every ViewManager. So should `UIManager.RCTView.NativeProps` still be merged with `viewConfig.NativeProps`, even if the individual ViewManager does not export/use them to begin with?
* Does this break other platforms? [UWP](https://github.com/Microsoft/react-native-windows)?
