Summary:
iOS and css have a different way to draw borders. Decision which rendering to use considers alpha value of given color as well.
If alpha=0 -> border is invisible -> we use ios render.
That doesn't work as expected in a case where only `borderWidth` property is set.
A default black color is used when no `borderColor` is set, but alpha checking logic will test `null`. Which resolves as alpha=0.

Summary:
When you call `-[RCTConvert UIFont:withFamily:...]` with a non-nil font object, we'll try to use the existing font object for system information. On iOS9+ which uses the San Francisco font, `[UIFont fontNamesForFamilyName:]` doesn't return anything useful, so we need to make sure that we detect this as a system font and use the appropriate methods. This issues is made worse by the fact that RCTTextView and friends recreate the font property for every attribute that is set (pretty horrible perf-wise).

Summary:
Sometimes is handy to check if a React node is a descendant of another node or not. For instance, I want to check if the focused `TextInput` is descendant of an specific `ScrollView`:
```js
const currentlyFocusedField = TextInput.State.currentlyFocusedField()
UIManager.viewIsAncestorOf(
currentlyFocusedField,
this.getInnerViewNode(),
(isAncestor) => {
if (isAncestor) {
console.log('The focused field is a descendant of this ScrollView!')
}
}
)
```
This function uses the same strategy as the `measureLayout` method to check if one node is an ancestor of other node. As the `measureLayout` method, this is performed outside the main thread.
By now I've only implemented the iOS version and its tests, but if this function is going to be merged I'll implement the Android version too. I have objc experience but no Java or Android, so I prefer to validate this functionality before jumping into developing the Android part.

Summary:
This uses `[UIImage imageNamed:]` to load local assets that are bundled using `require('../image/path.png')` and makes sure it is done synchronously on the main queue to prevent images from flickering. This improves user experience a lot when using large local images and prevents icon flickers to match the behaviour of most native apps.
This adds to methods to the ImageLoader protocol, one to tell if the image loader must be executed on the url cache queue and one to tell if the result of the image loader should be cached. I then use these to make the LocalImageLoader bypass the url cache queue and avoid caching images twice.
Note that this doesn't affect debug builds since images are loaded from the packager.
I'm not sure if we want to still support async loading of local images as I'm not sure how much of a perf difference this will make. Maybe someone at fb can benchmark this see how it affects your apps but there wasn't a noticeable one in mine. Also I only enabled this for loading png and jpg im

Summary:
Attempt to fix#7919.
Currently, if the app is launched into the background and you read `AppState.currentState` too soon, you will see the value `'active'` instead of `'background'`. This is because the default value of `AppState.currentState` is hardcoded to be `'active'` and it is initialized with the actual value asynchronously.
This attempts to fix the bug by having the `RCTAppState` module provide the initial state as a module constant.
As noted in #7919, it looks like this fix was already tried and reverted with 0fb3d8de83. zjj010104, hedgerwang, nicklockwood -- can you explain why? I would very much like to get this bug fixed.

Summary:
This diff exposes a new experimental method `[RCTJavaScriptLoader +attemptSynchronousLoadOfBundleAtURL:sourceLength:error:]`. It may be used if you know that a specific call site must load its JavaScript synchronously, or else fail entirely.
This new API will succeed for file URLs that point to a RAM bundle. It will fail for non-RAM-bundle files and for HTTP URLs.
This also cleans up the error domain and codes for this class. This should be the only externally visible change from this diff if you don't use the new API: the codes and domains you receive from the API may change slightly. They were pretty sloppy and undocumented before, so I think this change is for the better.

Summary:
The `initWithJSContextProvider:` API created a `RCTJSCExecutor` with a thread/context that already exists, but it did not solve the problem of loading an actual application script; the `executeApplicationScript:` API is also asynchronous.
Create a new merged API that allows you to pass in a pre-created thread/context pair and immediately receive an `RCTJSCExector` that has already executed a specified application script.
This also removes the `underlyingJSContext` API entirely, in favor of passing it back in a byref variable in the new API. This minimizes the surface area for API abuse.

- It can't come before that point because `_jscWrapper` has not been set up yet
- It can't come after that point since `self.context` would create the context there.
Just move the creation to be inline, enforced by assert. This makes it easier to reason about where the context is created, and easier to change how it is created later.

I didn't ValueProtect/ValueUnprotect since these are already globals, and those methods are not exposed on the JSC wrapper.

Summary:
Fix a bug that happens when views are added and removed in the same manageChildren block with a delete animation. What happens is that the inserted view is not inserted at the proper index if the deleted view index is smaller than the inserted one. This is because the view is not immediately removed from the subviews array so we need to offset the insert index for each view that is going to be deleted with an animation and is before the inserted view.
To do this I separated `_removeChildren` into 2 different functions, one for animated delete and one for normal delete. The animated one returns an array of `RCTComponent` that are going to be animated. We can then use this array to offset the insert index.
**Test plan (required)**
Tested that this fixed the bug in an app where I noticed it, also tested the UIExplorer example to make sure LayoutAnimations still worked properly.

Summary:
This diff implement the CSS z-index for React Native iOS views. We've had numerous pull request for this feature, but they've all attempted to use the `layer.zPosition` property, which is problematic for two reasons:
1. zPosition only affects rendering order, not event processing order. Views with a higher zPosition will appear in front of others in the hierarchy, but won't be the first to receive touch events, and may be blocked by views that are visually behind them.
2. when using a perspective transform matrix, views with a nonzero zPosition will be rendered in a different position due to parallax, which probably isn't desirable.
See https://github.com/facebook/react-native/pull/7825 for further discussion of this problem.
So instead of using `layer.zPosition`, I've implemented this by actually adjusting the order of the subviews within their parent based on the zIndex. This can't be done on the JS side because it would affect layout, which is order-dependent, so I'm doing it inside the view itself.
It works as follows:
1. The `reactSubviews` array is set, whose order matches the order of the JS components and shadowView components, as specified by the UIManager.
2. `didUpdateReactSubviews` is called, which in turn calls `sortedSubviews` (which lazily generates a sorted array of `reactSubviews` by zIndex) and inserts the result into the view.
3. If a subview is added or removed, or the zIndex of any subview is changed, the previous `sortedSubviews` array is cleared and `didUpdateReactSubviews` is called again.
To demonstrate it working, I've modified the UIExplorer example from https://github.com/facebook/react-native/pull/7825

Summary:
This diff refactors the view update process into two stages:
1. The `reactSubviews` array is set, whose order matches the order of the JS components and shadowView components, as specified by the UIManager.
2. The `didUpdateReactSubviews` method is called, which actually inserts the reactSubviews into the view hierarchy.
This simplifies a lot of the hacks we had for special-case treatment of subviews: In many cases we don't want to actually insert `reactSubviews` into the parentView, and we had a bunch of component-specific solutions for that (typically overriding all of the reactSubviews methods to store views in an array). Now, we can simply override the `didUpdateReactSubviews` method for those views to do nothing, or do something different.

Summary:
As per https://twitter.com/olebegemann/status/738656134731599872, our use of "main thread" to mean "main queue" seems to be unsafe.
This diff replaces the `NSThread.isMainQueue` checks with dispatch_get_specific(), which is the recommended approach.
I've also replaced all use of "MainThread" terminology with "MainQueue", and taken the opportunity to deprecate the "sync" param of `RCTExecuteOnMainThread()`, which, while we do still use it in a few places, is incredibly unsafe and shouldn't be encouraged.

Summary:
The `removeClippedSubviews` feature works by umounting views from the hierarchy if they move outside the bounds of their parent.
This was previously restricted to clipping views which had `overflow: hidden`, since we cannot efficiently check whether the subviews of a view go outside its bounds, and so clipping a view that has potentially overflowing children becomes an expensive recursive operation.
The problem with this is that `overflow: visible` is the default, and it's not well documented nor easy to tell that `removeClippedSubviews` has been set up correctly (i.e. with all children having `overflow: hidden`).
When I checked, I found that `removeClippedSubviews` was not working on any of the examples in UIExplorer, nor in several of our internal apps, because the views inside the ListView has `overflow: visible`. This was probably caused by an infra change at some point, but I'm not sure how long it's been broken.
It's vanishingly unlikely that anyone would ever deliberately want subviews to overflow their bounds in this scenario, so I've updated the logic to simply ignore the `overflow` property and assume that views should be clipped if you are using the `removeClippedSubviews` property on the parent.
Cons / Breaking changes: in some rare circumstances, a view might get clipped prematurely if its parent is outside the scrollview bounds, but it itself is inside. This doesn't occur in practice in any of our products, and could be worked around with additional wrapper views if it did.
Pros: removeClippedSubviews is now much easier to use, and much more likely to work as intended, so most list-based apps should see a performance improvement.

Summary:
RCTScrollView was calling `dockClosestSectionHeader` in `reactBridgeDidFinishTransaction`, which triggers a layout update. The reason for this was in case the `stickyHeaderIndexes` property was updated, which would require the headers to be adjusted.
However, doing this in `reactBridgeDidFinishTransaction` had the affect of causing `layoutSubviews` to be called repeatedly every frame even if nothing had changed and the scrollview wasn't moving, which was especially expensive when combined with the `removeClippedSubviews` logic, that loops through every view to calculate if it needs to be clipped.
This fix moves the `dockClosestSectionHeader` call into `didUpdateProps`, and checks that the stickyHeaderIndexes have actually changed before calling it.

Summary:
Allows developers to specify headers to include in the HTTP request
when fetching a remote image. For example, one might leverage this
when fetching an image from an endpoint that requires authentication:
```
<Image
style={styles.logo}
source={{
uri: 'http://facebook.github.io/react/img/logo_og.png',
headers: {
Authorization: 'someAuthToken'
}
}}
/>
```
Note that the header values must be strings.
Works on iOS and Android.
**Test plan (required)**
- Ran a small example like the one above on iOS and Android and ensured the headers were sent to the server.
- Ran a small example to ensure that \<Image\> components without headers still work.
- Currently using this code in our app.

Summary:
Previously, only Text and Image could be nested within Text. Now, any
view can be nested within Text. One restriction of this feature is
that developers must give inline views a width and a height via
the style prop.
Previously, inline Images were supported by using iOS's built-in support
for rendering images with an NSAttributedString via NSTextAttachment.
However, NSAttributedString doesn't support rendering arbitrary views.
This change adds support for nesting views within Text by creating one
NSTextAttachment per inline view. The NSTextAttachments act as placeholders.
They are set to be the size of the corresponding view. After the text is
laid out, we query the text system to find out where it has positioned each
NSTextAttachment. We then position the views to be at those locations.
This commit also contains a change in `RCTShadowText.m`
`_setParagraphStyleOnAttributedString:heightOfTallestSubview:`. It now only sets
`lineHeight`, `textAlign`, and `writingDirection` when they've actua
