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:
Adds a queue to postMessage so that messages sent close together are not lost.
Setting location="a";location="b" results in only "b" reaching shouldStartLoadWithRequest. Making the second update asynchronous with setTimeout does not fix the issue unless a delay is added.
With this update, postMessage queues "b" until it gets a "message:received" event that confirms "a" has already been processed.
The included test sends two messages from a webview and checks that both are received. It fails against the preexisting code with the first message being dropped.

**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:
**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.

Summary:
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.
