Summary:
Even so I know there are some opinions against ```margin: 0 auto``` it's still part of the spec: https://www.w3.org/TR/css-flexbox-1/#auto-margins and pretty usefull if you have to position via ```justify-content```.
This PR adds an implementation for that.
It adds an additonal ```YGUnitAuto``` and margins got ```YGNodeStyleSetMarginAuto``` functions as well.

Summary:
Motivation:
* `RCTShadowView`'s `frame` property actually represents computed layout of the view. We must not use it as a setter for yoga node styles;
* Using `frame` and `setLeftTop` in existing way actually works only for view with absolute positioning, so it is super rare and special case;
* Internally, setting `frame` only make sense to `RootView`, and in that case there we always must not change `origin` we are introducing `setSize` method.
Changes:
* `[-RCTShadowView setFrame:]` was removed, `frame` property is readonly now;
* `[-RCTShadowView setLeftTop:]` was removed; no replacement provided;
* `[-RCTShadowView size]` read-write property was added;
* `[-RCTUIManager setFrame:forView:]` was deprecated, use (just introduced) `setSize:forView:` instead;
* `[-RCTUIManager setSize:forView:]` was added.
If you are still need some of removed methods, you are probably doing something wrong. Consider using `setIntrinsicContentSize`-family methods,
`setSize`-family methods, or (in the worst case) accessing `yogaNode` directly.

Summary:
Eliminates a build warning related to the use of the deprecated `NSStringArray` typedef.
This fix was more complex than I'd anticipated because `NSStringArray` was also being used as part of a macro-generated selector name, and in two different ways for debug/release. I've added a macro which allows the selector name to be specified explicitly, thus generally allowing for converters which return arrays of templated types.
There's an argument for ditching `RCT_JSON_ARRAY_CONVERTER` in favour of `RCT_JSON_ARRAY_CONVERTER_NAMED` as they're both private, but `RCT_ARRAY_CONVERTER` is in the public API so we'd at least need to retain that. There are also arguments for ditching the use of the macro for the nested array case(s) - since afaik this is the only one at the moment. Feedback appreciated :)
Tested with the `UIExplorer` unit tests and by diffing the preprocessor output of `RCTConvert.m` in both release and debug configs, verifying that they're identical apart from that `NSStringArray` is replaced by

Summary:
Explain the **motivation** for making this change. What existing problem does the pull request solve?
This change is required when you try to set a focus on a view that doesn't exist and thus cannot be focused. In my specific use case, this occurred when trying to set a focus on a list item in a setInterval when the View (with the specific list item) had been popped. The while loop ran infinitely (eventually freezing the app) since the rootView doesn't exist. This adds that check and breaks out if so.
All obj-c tests ran successfully.

Summary:
In the context of an app an image exists in three resolutions on the server: `thumb` (30px) `feed` (300px) `full` (900px). When looking at an individual item a user can come either from the feed, via a permalink or from other parts of the app. This allows a situation where the `feed` image might or might not already be loaded somewhere in the app. In the detail view I want to render `thumb` with a blur (to quickly display something), then the `feed` image if it exists to have something decent to display until `full` loads. However it is quite a waste to load the `feed` image if it isn't already in cache, and will slow down the time until `full` is loaded. It is possible to track the navigation from feed->detail and that the `feed` image has actually completed loading by the feed component however as component hierarchies grow this turns into quite a lot of prop passing and bad separation of concerns.

As per janicduplessis recommendation, provide a new synchronous method to replace the necessary synchronous calls and use a warning in the comments (and method name).
**Motivation**
There are currently a number of XCode warnings that show up in a fresh 0.40 install of a react native project. While the project can still be run, this contributes negatively to the development experience -- valid warnings may be ignored and new ones may be added as per https://en.wikipedia.org/wiki/Broken_windows_theory
This addresses one of the warnings, by providing the functionality of a deprecated method in two specific cases where we can't avoid doing synchronous work on the main queue. See https://github.com/facebook/react-native/issues/11736 for more context.

```react-native/React/Modules/RCTRedBox.m:406:58: Conversion from value of type 'NSArray<RCTJSStackFrame *> *' to incompatible type 'NSArray<NSDictionary *> *```
This appears because the compiler is left to infer the type of `stack`, and it does so as `NSArray<RCTJSStackFrame *>` based on [RCTRedBox.m#L390](https://github.com/facebook/react-native/blob/master/React/Modules/RCTRedBox.m#L390). In reality `stack` may be either of two types and the function body deals with normalisation.
Mark the stack as explicitly `NSArray<id>` to prevent inference so we're free to make the decision to cast to more specific types.

Summary:
Currently, < WebView > allows you to pass JS to execute within the view. This works great, but there currently is not a way to execute JS after the page is loaded. We needed this for our app.
We noticed that the WebView had messaging support added (see #9762) . Initially, this seemed like more than enough functionality for our use case - just write a function that's injected on initial load that accepts a message with JS, and `eval()` it. However, this broke once we realized that Content Security Policy can block the use of eval on pages. The native methods iOS provide to inject JS allow you to inject JS without CSP interfering. So, we just wrapped the native methods on iOS (and later Android) and it worked for our use case. The method injectJavaScript was born.
Now, after I wrote this code, I realized that #8798 exists and hadn't been merged because of a lack of tests. I commend what was done in #8798 as it sorely solves a problem (injecting JS after the initial load) and has more features than what I'

This changes our xcode setup to use a copy files phase instead.

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:
There was a bug in the view clipping logic.
Clipping works on uiview hierarchy, but I've been using `reactSuperview` to get clipping rect for my parent.
This is incorrect in a case where these two hierarchies don't match and there are some views between a view and its `reactSuperview`.
So we should really use normal `superview`. A minor complication is that `superview` is `nil` if we are clipped.
We could remember what our last `superview` was, but that's extra data we have to manage. Instead I use one clever trick to avoid doing so.

Summary:
React view hierarchy doesn't have to always match uiview hierarchy. Plus if we clip view we loose knowledge about view's react superview if we just use `self.superview` as react superview.
This diff fixes it by storing a strong ref to reactSuperview in an associated object.
This is needed for new view clipping implementation (see the dependent diff).

Summary: The goal of this diff is to have assertion failures show up as error logs on Android. To do this, I updated the logging API to take calls with log levels. We now have to pass around va_list unfortunately since you can't re-expand or pass along var-args to a subcall.

Summary:
Solves issue #7632 where fonts with only a single font weight/type would not render.
Example of a built-in font that would not render is `Zapfino` and other custom fonts like `Impact` would not render.

Summary:
Fixes#4740, where views would unnecessarily be retained after performing `navigator.pop()` - this was particularly problematic for big lists and memory-intensive custom views.
This fix causes no functional change: `_previousViews` are only used in the loop starting at line 564 to ensure that the JavaScript and Native navigation stacks are equivalent at all times. As we do in this fix, that loop limits itself to only the views expected to be on the React navigation stack. So overall this change makes the code logically 'more correct'.
Tested by checking that `_previousViews.count` is always equivalent to `previousReactCount` in the loop (which means we could remove the complex `MIN(... MIN(previousReactCount, _previousViews.count)` in the loop too, but I wanted to keep the diff as small as possible for now).

Summary: Instead of silently ignorning non-leaf nodes with measure functions, we should assert that we don't create those kinds of trees.

Summary:
UIScrollView's internal logic with scroll indicator dies when bad values (e.g. NaN/Infinity) are set on the position/size.
We already guard UIManager with these checks but the RCTScrollView's underlying scrollview (RCTCustomScrollView) can get these set from other places, and we're seeing crashes in this area.

Summary:
**Motivation**
I'm working on a project that uses React Native and needs to add direct synchronous bindings to native stuff through the JavaScriptCore C API. This is because it's performance-sensitive and would benefit from the quickest JS->C path. It does this using cross-platform C++ code that works on both iOS and Android. Most of the infrastructure for getting access to the JSC context is already in React Native actually, just had to add a few more things.
(lexs you mentioned to tag you in this pull request)
**Test plan**
Modify the JavaScriptCore context through the `JSContextRef` returned (eg. add an object at global scope) and verify that it exists in JavaScript.

Summary:
Explain the **motivation** for making this change. What existing problem does the pull request solve?
See https://github.com/facebook/react-native/issues/10506. A native `NSError` with `NSUnderlyingErrorKey` set causes a JSON stringify error from the websocket dispatcher if remote debugging is enabled.
**Test plan (required)**
I'm not familiar with the react native testing framework. Happy to add a test for this if someone can point me to where this part of the codebase is exercised :)
I did some spot checks with nil user dictionaries and nil underlying errors here. The case that this solves is testable using https://github.com/superseriouscompany/react-native-error-repro, specifically:
```objective-c
NSError *underlyingError = [NSError errorWithDomain:@"underlyingDomain" code:421 userInfo:nil];
NSError *err = [NSError errorWithDomain:@"domain" code:68 userInfo:@{@"NSUnderlyingError": underlyingError}];
reject(@"foo", @"bar", err);
```

Summary:
1. Using weak container to hold the currently opened alerts.
2. Using weak reference to alertController in action handler block.
3. BTW, remove the unused vars: _alertCallbacks, _alertButtonKeys.
Test plan (required)
```
- (void)invalidate
{
for (UIAlertController *alertController in _alertControllers) {
[alertController.presentingViewController dismissViewControllerAnimated:YES completion:nil];
}
}
```
Since we use weak container, _alertControllers should only contains the currently opened alerts.
I test this way: Put a breakpoint in invalidate, open the UIExplorer play with the 'Alert' & 'AlertIOS' examples, then fire a reload and see if _alertControllers contains the expected values.
