Summary:
This PR fixes a bug where in `RCTNetworking` not all tasks/handlers were not being cleared when invalidating the class.
I came across this issue when writing some unit tests for my native plugins, sometimes a test would finish running (and the bridge invalidated), and only afterwards a callback from RCTNetworking would come, resulting in this exception:

Bug can be reproduced by making a `XMLHttpRequest` (uses `RCTNetworking` internally) that takes a couple seconds to perform, and issuing a RCTBridge reload command in the meantime.
You can add the following code to the react-native template project,
```
componentDidMount() {
var oReq = new XMLHttpRequest();
oReq.addEventListener("load", () => console.log('Finished'));
oReq.open("GET", "https://www.dropbox.com/s/o01hz0chqvjafhv/file.bin?dl=1");
oReq.send();
console.log('Request is being performed...')
}
```
In my case I download a 1MB file.
Run the project and reload the a couple times. Bug is triggered.

Summary:
We currently handle empty body poorly in the iOS blob implementation, this happens because of an early return that cause the blob response to not be processed by the blob module, resulting in an empty string as the body instead of a blob object. We also need to make sure to create an empty blob object when data is nil (empty body) as per the XMLHttpRequest spec. The Android implementation was already handling this properly.
Fixes#18223

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:
It's currently possible to crash React Native on iOS when using XMLHTTPRequest with onreadystatechange by having the server send a bunch of bad unicode (we found the problem when a bad deploy caused this to happen).
This is due to an integer overflow when handling carryover data in decodeTextData.
Create Express server with mock endpoint:
```js
var express = require('express');
var app = express();
app.get('/', function(req, res) {
res.writeHead(200, {'content-type': 'text/plain; charset=utf-8'});
res.flushHeaders();
res.write(new Buffer(Array(4097).join(0x48).concat(0xC2)));
res.write(new Buffer([0xA9]));
res.end();
});
app.listen(3000);
```
Create React Native application which tries to hit the endpoint:
```js
export default class App extends Component<{}> {
componentDidMount() {
const xhr = new XMLHttpRequest()
xhr.open('get', 'http://localhost:3000', true);
xhr.onreadystatechange = function () {
if(xhr.readyState === XMLHttpRequest.DONE && xhr.status === 200) {
console.warn(xhr.responseText);
}
};
xhr.send();
}
render() {
return null;
}
}
```
Observe that the application crashes when running master and doesn't when including the changes from this pull request.

Summary:
Corresponding Android PR: #12276
Respect the withCredentials XMLHttpRequest flag for sending cookies with requests. This can reduce payload sizes where large cookies are set for domains.
This should fix#5347.
This is a breaking change because it alters the default behavior of XHR. Prior to this change, XHR would send cookies by default. After this change, by default, XHR does not send cookies which is consistent with the default behavior of XHR on web for cross-site requests. Developers can restore the previous behavior by passing `true` for XHR's `withCredentials` argument.
**Test plan (required)**
Verified in a test app that XHR works properly when specifying `withCredentials` as `true`, `false`, and `undefined`. Also, my team uses this change in our app.

is(types) {
if (!types) return typeis(this.req);
if (!Array.isArray(types)) types = [].slice.call(arguments);
return typeis(this.req, types);
}
// type-is index.js (line 237)
function normalizeType (value) {
// parse the type
var type = typer.parse(value)
// remove the parameters
type.parameters = undefined
// reformat it
return typer.format(type)
}
// media-typer

Summary:
To make React Native play nicely with our internal build infrastructure we need to properly namespace all of our header includes.
Where previously you could do `#import "RCTBridge.h"`, you must now write this as `#import <React/RCTBridge.h>`. If your xcode project still has a custom header include path, both variants will likely continue to work, but for new projects, we're defaulting the header include path to `$(BUILT_PRODUCTS_DIR)/usr/local/include`, where the React and CSSLayout targets will copy a subset of headers too. To make Xcode copy headers phase work properly, you may need to add React as an explicit dependency to your app's scheme and disable "parallelize build".

Summary:
This is **a critical issue**.
The issue arises when incremental networking is enabled from JS by setting `onprogress` or `onload` on an `XMLHttpRequest` object.
The results:
Unicode characters get corrupted seemingly in random. The issue is from the way Unicode character parsing is handled in `RCTNetworking.mm`. When incremental networking is enabled, each chunk of data is decoded and passed to JS:
```objective-c
incrementalDataBlock = ^(NSData *data, int64_t progress, int64_t total) {
NSString *responseString = [RCTNetworking decodeTextData:data fromResponse:task.response];
if (!responseString) {
RCTLogWarn(@"Received data was not a string, or was not a recognised encoding.");
return;
}
NSArray<id> *responseJSON = @[task.requestID, responseString, @(prog

Summary:
Currently when doing a file upload, the Content-Type header gets set to whatever MIME type iOS computed for the file. The Content-Type header the developer provided never takes precedence.
For example, when uploading an image, iOS might determine that the MIME type is "image/jpeg" and so this would be the Content-Type of the HTTP request. But the developer might need the Content-Type to be "application/octet-stream". With this change, if the developer provides a Content-Type header, it will not be overriden.
There is only one exception to this rule which is for "multipart" requests. In this case, the developer's Content-Type header is always ignored. This is because the Content-Type header needs to contain the boundary string and that information is not available to the developer in JavaScript.
This change makes iOS's behavior more consistent with Android's.
**Test plan (required)**
In a small test app, verified that the developer's Content-Type header takes precedence when it's provided. Verif
