Summary:
This adds support for sticky headers on Android. The implementation if based primarily on the iOS one (https://github.com/facebook/react-native/blob/master/React/Views/RCTScrollView.m#L272) and adds some stuff that was missing to be able to handle z-index, view clipping, view hierarchy optimization and touch handling properly.
Some notable changes:
- Add `ChildDrawingOrderDelegate` interface to allow changing the `ViewGroup` drawing order using `ViewGroup#getChildDrawingOrder`. This is used to change the content view drawing order to make sure headers are drawn over the other cells. Right now I'm only reversing the drawing order as drawing only the header views last added a lot of complexity especially because of view clipping and I don't think it should cause issues.
- Add `collapsableChildren` prop that works like `collapsable` but applies to every child of the view. This is needed to be able to reference sticky headers by their indices otherwise some subviews can get optimized out and break indexes.

Summary:
(I changed a ton from when I previously submitted this PR so please take another look if you already did.)
PROBLEM: the no-longer-maintained `esprima-fb` parser does not support class properties, leading our website docgen to die if we use class properties, which we're gonna do real soon now
SOLUTION: use `flow-parser` instead, which the flow team is maintaining including all the fancy-pants ES? stuff that FB uses internally.
This removes the `esprima-fb` parser from jsdocs and replaces it with `flow-parser`. It's almost the same, I checked by diffing all the parser json output and it only had a few irrelevant differences. I had to add a file of constants so that we could remove esprima-fb altogether, too.
This also adds a couple unit tests, so that we can test that jsDocs works programmatically. They don't run if you run the regular RN tests, you have to run `npm test` from the `/website/` subdirectory.

Summary:
For example, I could have a root named `random` and another root named `randomColor`.
A child of `randomColor` would **incorrectly** pass as a descendant of `random`.
So this commit changes `isDescendant` to do 2 things:
- check for exact matches (eg: the path is a root)
- call `startsWith` like before, but append `path.sep` to avoid false positives

Summary: Introduce `overflow:scroll` so that scrolling can be implemented without the current overflow:visible hackiness. Currently we use AT_MOST to measure in the cross axis but not in the main axis. This was done to enable scrolling containers where children are not constraint in the main axis by their parent. This caused problems for non-scrolling containers though as it meant that their children cannot be measured correctly in the main axis. Introducing `overflow:scroll` fixes this.

Summary:
This piece of code can assemble all transitive dependencies of a set of entry modules. It is supposed to replace `ResolutionRequest.getOrderedDependencies`.
It has the following advantages:
- has minimal API surface to other components of the system (uses two functions, exposes one function)
- allows to separate concerns into loading + transforming files, resolving dependencies, gathering all modules belonging to a bundle (this code), and bundling
- allows to specify multiple entry points
- allows to use any kind of dependency ID as entry point (haste IDs, node module IDs, relative paths, absolute paths – depends on the resolver)
- allows to skip files, which allows callers to incrementally update previously retrieved collections of modules

Summary:
This automatically changes the size of the modal by listening to dialog size changes and propagating
those changes through UIManager.
In detail: I've looked into three ways of doing this:
1. Send `onSizeChanged` events/info from the View to the CSSNode directly. This is kinda hacky because you would need to hold a reference to the CSSNode somewhere, either in the View or in the ViewManager. But then you'll have to take care of the lifecycle of the CSSNode, so that you don't update it after it has been dismissed. Not great.
2. The version we went for, is to just update the size of the corresponding CSSNode in the same way we do it for root nodes: we inform the UIManager that the size of the root node has changed, and it will propagate that change, triggering a `dispatchViewUpdates` if none is underway, so that the layout is updated.
3. The other solution we thought of is to treat the Modal as a root view. This would mean rendering an application with the tag of the Modal as the root of the application. That tag would be received by calling some method into UIManager and ReactModalHostManager to create a new RootView, create a Dialog and plop the root view in it. The idea was to maintain the JS API that we now have, but make the implementation more correct (ie. since both RootView and the Modal must deal with touch handling), and could have other benefits (ie. no hacks necessary for making the inspector work on top of modals). However, the change is not trivial and I don't know just how much code would have to be changed to make this work correctly. We might revisit this at a later stage, after we've done more work on having several root views at the same time in the app.

Summary:
If the packager is already watching `/path/to/MyProject`, and it finds symlinks inside `/path/to/MyProject/node_modules` that point to `/path/to/MyProject/path/to/somewhere/else`, there's no need to add the latter to the project roots.
**Test Plan:** replicate an aforementioned project set-up, and verify that only `/path/to/MyProject` is a project root for the packager, while files in `/path/to/MyProject/path/to/somewhere/else` can still be imported so long as they're part of an npm-style package (e.g. `/path/to/MyProject/path/to/somewhere/else/package.json` exists).

Summary:
Setting the line height with the help of Android-provided StaticLayout is incorrect. A
simple example app will display the following when `setLineSpacing(50.f, 0.f)`
is set: {F62987699}. You'll notice that the height of the first line is a few
pixels shorter than the other lines.
So we use a custom LineHeightSpan instead, which needs to be applied to the text
itself, and no height-related attributes need to be set on the TextView itself.

This is just D3835023 again since it got reverted, plus the fix from D3841918 baked in. Here's the old summary:
We never actually closed the websocket connection. Furthermore, upon calling `closeQuietly()`, `onClose()` is called, which does `reconnect()`. This results in ReactInstanceManager leaking after calling `destroy()` and nullifying all references to it.
To fix this I made sure `closeQuietly()` actually closes the connection for good, and made sure we actually call it when destroying an instance.

- Being able to call these from JS is really useful in envs where action sheets are not available (eg: App Extensions). I made the functions act as explicit toggles, this way it's easy to set the wanted behavior.

Summary:
Fixes https://github.com/facebook/react-native/issues/9216.
As nickzuber describes in #9216, conditional `Picker.Item` elements will lead to exceptions downstream when the `Picker` attempts to construct the collection of items.
[In the picker source](a2fb703bbb/Libraries/Components/Picker/PickerIOS.ios.js (L48-L53)) we can see that `child.props` is accessed when `child` has the potential to be an invalid `React` element.
```js
ReactChildren.forEach(props.children, function (child, index) {
if (child.props.value === props.selectedValue) {
selectedIndex = index;
}
items.push({value: child.props.value, label: child.props.label});
});
```
This change ensures the incoming element is valid
```diff
ReactChildren.forEach(props.children, function (child, index) {
+ if (!React.isValidElement(child)) {
+ return;
+ }
if (child.props.value === props.selectedValue) {
selectedIndex = index;
}

Summary:
Added details about how IOS Native Modules can be initialized & registered manually with custom initializers so that dependencies can be injected to said modules.
Please let me know if there is a more appropriate place to detail this in the documentation or this is in fact detailed elsewhere; I also believe we do not have documentation on how to do the equivalent on Android, however it is a bit more obvious as the automatic MACRO registration mechanism does not exist on Android and modules need to be initialized manually anyway. As I currently understand there isn't currently any documentation detailing this apart from comments in the source.
Please let me know if you would require any style changes (variable names etc), to be more en-keeping with the rest of the documentation.
