Summary:
This diff adds a testing screen dev route to the facebook app for testing generated view configs
It's not pretty (i have 0 tetra experiance) but it gets the job done
There are three cases handled:
- No generated config �
- Invalid generated config (useful for dev) �
- Valid generated config �
On the description page we:
- Redbox it it's invalid (this could be used to redbox test all host components)
- Show diffs of the view config properties
- List all of the generated config properties
- List all of the native config properties
Using this tool, it's easy to see what the current config on native is, add correct flow types for the generated config, and validate the generated config
Coming later: adding all of the native configs to the list (will probably need filtering)

Summary:
This is the next step in moving RN towards standard path-based requires. All the requires in `Libraries` have been rewritten to use relative requires with a few exceptions, namely, `vendor` and `Renderer/oss` since those need to be changed upstream. This commit uses relative requires instead of `react-native/...` so that if Facebook were to stop syncing out certain folders and therefore remove code from the react-native package, internal code at Facebook would not need to change.

I was looking at the coverage report of the JavaScript code in the `Libraries` folder, and found some of the modules and functions to be (partially) untested. I believe that adding tests to them would formally capture their behaviour and avoid future regressions. In this PR, I've added some unit tests for 3 utility components.
Perhaps a more general question: Are these kinds of PRs appreciated? I'd be interested in submitting more of them in the future.

Summary:
This PR introduces a new helper function called `setAndForwardRef`. It is intended to help with moving components that depend on `NativeMethodsMixin` off of `createReactClass`.
It allows for classes that depend on having a ref to a native component to be able to also forward the native component ref to user code.
Usage is like this:
```js
class MyView extends React.Component {
_nativeRef = null;
_setNativeRef = setAndForwardRef({
getForwardedRef: () => this.props.forwardedRef,
setLocalRef: ref => {
this._nativeRef = ref;
},
});
render() {
return <View ref={this._setNativeRef} />;
}
}
const MyViewWithRef = React.forwardRef((props, ref) => (
<MyView {...props} forwardedRef={ref} />
));
module.exports = MyViewWithRef;
```

Summary:
This PR fixes a bug in `deepFreezeAndThrowOnMutationInDev` which did not take into account that objects passed to it may have been created with `Object.create(null)` and thus may not have a prototype. Such objects don't have the methods `hasOwnProperty`, `__defineGetter__`, or `__defineSetter__` on the instance.
I ran into an unrecoverable error in React Native when passing this type of object across the bridge because `deepFreezeAndThrowOnMutationInDev` attempts to call `object.hasOwnProperty(key)`, `object.__defineGetter__` and `object__defineSetter__` on objects passed to it. But my object instance does not have these prototype methods.
Changes:
* Defined `Object.prototype.hasOwnProperty` as a `const` (pattern used elsewhere in React Native)
* Modified calls to `object.hasOwnProperty(key)` to use `hasOwnProperty.call(object, key)` (Per ESLint rule [here](https://eslint.org/docs/rules/no-prototype-builtins))
* Modified calls to deprecated methods `object.__defineGetter__` and `object.__defineSetter__` to instead use `Object.defineProperty` to define get and set methods on the object. (Per guidance on [MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/__defineGetter__))
* Added a new test to `deepFreezeAndThrowOnMutationInDev-test` to verify the fix.
I tried to create a reproducible example to post to Snack by passing prototype-less objects to a `Text` component, in various ways, but they appear to be converted to plain objects before crossing the bridge and therefore they do not throw an error.
However, I was able to create a new test to reproduce the issue. I added the following test to `deepFreezeAndThrowOnMutationInDev-test`:
```JavaScript
it('should not throw on object without prototype', () => {
__DEV__ = true;
var o = Object.create(null);
o.key = 'Value';
expect(() => deepFreezeAndThrowOnMutationInDev(o)).not.toThrow();
});
```
The changes in this PR include this new test.
ESLint test produced no change in Error count (3) or Warnings (671)

Summary:
If tracking is enabled and the sampling check passes on a scroll or layout event,
we compare the scroll offset to the layout of the rendered items. If the items don't cover
the visible area of the list, we fire an `onFillRateExceeded` call with relevant stats for
logging the event through an analytics pipeline.
The measurement methodology is a little jank because everything is async, but it seems directionally
useful for getting ballpark numbers, catching regressions, and tracking improvements.
Benchmark testing shows a ~2014 MotoX starts hitting the fill rate limit at about 2500 px / sec,
which is pretty fast scrolling.
This also reworks our frame rate stuff so we can use a shared `SceneTracking` thing and track blankness
globally.

Summary: The utf-8 test was failing when run from Jest’s cache, because it contained unicode escape sequences for stray high and low surrogates. Somewhere in the process of transpiling, caching on disk, and reading from the cache, those stray surrogates are changed to U+FFFD (REPLACEMENT CHARACTER / �). This diffs changes the method of creating these strings from literals to `String.fromCharCode`, which survives the process as intended.

Summary:
* Next version of Jest doesn't allow non test files in __tests__ folders.
* I'm trying to switch all tests off of jsdom on react-native. This should save 500ms of time when running a single test because jsdom is slow to load and react-native is also not supposed to run in a DOM environment, so let's not pretend we are providing the DOM in tests.
* Make the bridge config configurable so that when we disable automocking and we reset the registry we can redefine the value.
Oh also, stop using lodash in Server.js. First off, lodash 3 doesn't work in Jest's node env because it does some crazy stuff, second because we don't need to load all of lodash for debounce.

Summary:
Kudos to frantic for this amazing idea! Works really well (yet so simple!)
Basically we had a discussion with vjeux and frantic and others in the PR #7033 how to handle platform-specific stylesheets in a similar to F8 app way.
There were quite a few nice ideas there, however that one seems to be the smallest yet the most powerful.
Basically there's a `Platform.select` method that given an object, will select a `obj[Platform.OS]` value.
It works with styles:
`Platform.select({ ios: {}, android: {} })`
with messages:
`<Text>{Platform.select({ ios: 'Check the App Store', android: 'Check Google Play' })}</Text>`
and also works well with components (similar to Wallmart idea of <PlatformSwitch />) - relevant example included in diff.

Summary:
I'm working on deploying haste2 with jest. This updates all the files that require changes for this to work and they are backwards compatible with the current version of jest.
* package.json was just outdated. I think haste1's liberal handling with collisions made this a "non-issue"
* env.js didn't properly set up ErrorUtils, also unsure why that isn't a problem in jest right now already?
* some things were mocking things they shouldn't
* Because of the regex that matches against providesModule and System.import, it isn't possible to list module names more than once. We have multiple tests reusing the same providesModule ids and using System.import with modules that only exist virtually within that test. Splitting up the strings makes the regexes work (we do the same kind of splitting on www sometimes if we need to) and using different providesModule names in different test files fixes the problem. I think the BundlesLayoutIntegration-test is going to be deleted, so this doesn't even matter.

Summary:
The JavaScript ecosystem doesn't have the notion of a built-in native module loader. Even Node is decoupled from its module loader. The module loader system is just JS that runs on top of the global `process` object which has all the built-in goodies.
Additionally there is no such thing as a global require. That is something unique to our providesModule system. In other module systems such as node, every require is contextual. Even registered npm names are localized by version.
The only global namespace that is accessible to the host environment is the global object. Normally module systems attaches itself onto the hooks provided by the host environment on the global object.
Currently, we have two forms of dispatch that reaches directly into the module system. executeJSCall which reaches directly into require. Everything now calls through the BatchedBridge module (except one RCTLog edge case that I will fix). I propose that the executors calls directly onto `BatchedBridge` through an instance on the global so that everything is guaranteed to go through it. It becomes the main communication hub.
I also propose that we drop the dynamic requires inside of MessageQueue/BatchBridge and instead have the modules register themselves with the bridge.
executeJSCall was originally modeled after the XHP equivalent. The XHP equivalent was designed that way because the act of doing the call was the thing that defined a dependency on the module from the page. However, that is not how React Native works.
The JS side is driving the dependencies by virtue of requiring new modules and frameworks and the existence of dependencies is driven by the JS side, so this design doesn't make as much sense.
The main driver for this is to be able to introduce a new module system like Prepack's module system. However, it also unlocks the possibility to do dead module elimination even in our current module system. It is currently not possible because we don't know which module might be called from native.
Since the module system now becomes decoupled we could publish all our providesModule modules as npm/CommonJS modules using a rewrite script. That's what React Core does.
That way people could use any CommonJS bundler such as Webpack, Closure Compiler, Rollup or some new innovation to create a JS bundle.
This diff expands the executeJSCalls to the BatchedBridge's three individual pieces to make them first class instead of being dynamic. This removes one layer of abstraction. Hopefully we can also remove more of the things that register themselves with the BatchedBridge (various EventEmitters) and instead have everything go through the public protocol.

Summary:
@public
The current implementation of `MessageQueue` is huge, over-complicated and spread
across `MethodQueue`, `MethodQueueMixin`, `BatchedBridge` and `BatchedBridgeFactory`
Refactored in a simpler way, were it's just a `MessageQueue` class and `BatchedBridge`
is only an instance of it.
Test Plan:
I had to make some updates to the tests, but no real update to the native side.
There's also tests covering the `remoteAsync` methods, and more integration tests for UIExplorer.
Verified whats being used by Android, and it should be safe, also tests Android tests have been pretty reliable.
Manually testing: Create a big hierarchy, like `<ListView>` example. Use the `TimerMixin` example to generate multiple calls.
Test the failure callback on the `Geolocation` example.
All the calls go through this entry point, so it's hard to miss if it's broken.
