Summary:
This PR is a followup to https://github.com/facebook/react-native/pull/11417 and should be merged after that one is merged.
1. Add support for creating blobs from strings, not just other blobs
1. Add the `File` constructor which is a superset of `Blob`
1. Add the `FileReader` API which can be used to read blobs as strings or data url (base64)
1. Add support for uploading and downloading blobs via `XMLHttpRequest` and `fetch`
1. Add ability to download local files on Android so you can do `fetch(uri).then(res => res.blob())` to get a blob for a local file (iOS already supported this)
1. Clone the repo https://github.com/expo/react-native-blob-test
1. Change the `package.json` and update `react-native` dependency to point to this branch, then run `npm install`
1. Run the `server.js` file with `node server.js`
1. Open the `index.common.js` file and replace `localhost` with your computer's IP address
1. Start the packager with `yarn start` and run the app on your device
If everything went well, all tests should pass, and you should see a screen like this:

Summary:
This is a simple groundwork PR to allow options to be passed to the `WebSocket` constructor. It represents a minor change to an undocumented part of the API, moving `headers` to within `options`.
This will be a BC for anyone manually specifying headers other than `origin` but a) that's not a common use case with WebSockets and b) it's not documented even in code and wouldn't currently pass a flow check.
NB: The third argument to the WebSocket constructor isn't part of the W3C spec, so I think this is a good place for RN-specific named parameters, better than adding a fourth argument. `protocols` needs to stay where it is, in line with the spec.
If this goes through I'd like to build on it by adding an additional connection option for SSL certificate pinning, as already supported by the underlying `okhttp` and `RCTSRWebSocket`. It could later be expanded for various other uses.
Currently, there's no way for a `WebSocket` user to specify any connection options other than url, protocol and headers. The fact that `WebSocket` connects in its constructor means any options have to go in there.
Connect to a websocket server using iOS and Android, observe the connection headers:
1. Without specifying `origin`, the default header should be set
2. Specifying it in the old way `new WebSocket(url, protocols, { origin: 'customorigin.com' })`
3. Specifying it in the new way `new WebSocket(url, protocols, { headers: { origin: 'customorigin.com' }})`.
I've tested myself using the test app with iOS and Android.

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:
I discovered this while trying to pinpoint why Nuclide Inspector integration with RN is so flaky. It turns out that, for some reason, if I create a `WebSocket` instance early enough (which I need to when setting up DevTools integration), and the connection is fast enough (which it is on localhost), the `websocketOpen` message may arrive earlier than an `onopen` event handler is registered, causing the `onopen` handler to never fire.
```
mkdir ~/my-server
cd ~/my-server
npm i ws
nano index.js
```
Paste this code:
```js
const ws = require('ws');
const wss = new ws.Server({
port: 8099
});
```
Run the server:
```js
node index.js
```
Now, inside React Native, paste right after [these lines](57010d63b6/Libraries/Core/InitializeCore.js (L193-L194)):
```js
const ws = new window.WebSocket('ws://localhost:8099');
ws.onopen = function() {
alert('open!');
};
```

Summary:
Fix for https://github.com/facebook/react-native/issues/9465
We are building a react-native based application which extensively uses WebSockets. The Android app crashes right after waking up being in suspended mode for a coupe of days and throws an exception:
"Cannot send a message. Unknown WebSocket id 1"
Before calling WebSocket.send(...) method from WebSocket.js we always check its readyState. I believe the problem is caused by not updating readyState if case of 'websocketFailed' event. this.close() cause the current used websocket ID to be removed from mWebSocketConnections HashMap (WebSocketModule.java), but readyState stays the same.

Summary:
Idle WebSocket connections get reset after a few minutes of inactivity. To prevent this, most WebSocket implementations offer sending special ping messages. This PR adds a method `sendPing()` to WebSocket. Ping payloads are not supported.
Manual testing can be done by adding `connection.on('ping', _ => console.log('Received ping'));` to a ws connection or using a packet sniffer while sending pings.

Summary:- Get rid of no longer necessary WebSocket.js v WebSocketBase.js split
- Use `EventTarget(list, of, events)` as base class to auto-generate `oneventname` getters/setters that get invoked along with other event handlers
- Type annotation `any` considered harmful, especially when we can easily spell out the actual type
- Throw in some `const` goodness for free
**Test Plan:** Launch UIExplorer example app, supplied `websocket_test_server` script, and try different combinations of sending and receiving text and binary data on both iOS and Android.

Summary:This is a follow up of 9b87e6c860.
- Allows custom headers on connection request
- Adds a default `origin` header to Android, just like iOS
**Introduces no breaking changes.**
I was working on something similar and would like to propose a few changes that make the API more consistent across both iOS and Android platforms and brings this closer to [spec](https://tools.ietf.org/html/rfc6455).
I believe aprock first implementation of adding custom `headers` was correct. It makes sense naming this argument `headers` since we have no other general options available, and the current `options` field is being used to pass in a header anyway.
My use case for custom headers was attaching a token to the `Authorization` header on the connection request. I have been testing this by passing a JWT inside the `Authorization` header and verifying it on the server before establishing a connection.

Summary:Motivation: Developer expects `onclose` to be called before/during close of the websocket. The `websocketFailed` event triggers a close but does not invoke onclose.
Testplan: Connect to a websocket server from android, terminate the server, observe that onerror is called, the websocket is closed, but onclose is not called.
Note: the observed bug is in android only because in iOS the underlying websocket implementation fires the `websocketClosed` rather than `websocketFailed` event when the server terminates. Nevertheless, the justification for this change stands that regardless of the cause of the close, if `this.close` is called it is expected this.onclose should be called as well.
