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:
Following the PR https://github.com/facebook/react-native/pull/6195, this adds a `HEIGHT` constant on `StatusBar` for iOS.
Combined with `statusBarFrameDidChange` and `statusBarFrameWillChange` StatusBar native events, it solves various problems with In-Call cellar bar / Location bar / others 40pt status bars, and offers a correct `keyboardVerticalOffset` value for the KeyboardAvoidingView component.

Summary: Switch to using IS_TESTING on the Platform module. While IS_TESTING has to be explicitly set in the test harness, this makes it more usable and stops people from relying on brittle variables in the (larger) environment.

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.

There were no tests for this method, and I searched the whole project to make sure we weren't relying on it anywhere.

Summary:
Right now from JS there's no way to see the environment variables or arguments that the application was started with.
The main use case for this is to help enable/disable features when being run in a testing environment (as environment variables are the easiest way to communicate).
javache is it okay to reference these constants from JS at startup time? I am planning to disable yellow boxes via an environment variable.
achen1 how easy is it expose these two things for Android as well?

Summary:
Currently a build warning is thrown by `if (header.BCVersion != runtimeBCVersion) ...` because `runtimeBCVersion` is signed, apparently because `-1` is used to mean that the runtime has no support for bytecode bundles.
This PR splits out the error case of the runtime not supporting BC bundles from the case of a version mismatch.
Tested as much as I could by building and running `UIExplorer` - I haven't attempted to use real bytecode bundles.

Summary:
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.
**Test plan (required)**
I ran a project that relied on screen size and it didn't crash...happy to do more involved testing if someone can share better methodology.

Summary:
Fixes the build warning:
```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.

`UIActivityViewConroller.completionHandler` has been [deprecated](https://developer.apple.com/reference/uikit/uiactivityviewcontroller/1622010-completionhandler) since iOS 8, when it was replaced by `completionWithItemsHandler`.
Tested the build using `UIExplorer` and XCode 8.2 but I've never seen and can't work out how to activate the `UIActivityViewController` this method relates to, so I haven't tested a real run.

Motivation: reduce build noise that might worry new users or hide real problems.
This deals with four of the warnings currently in the iOS build. The `__unused` additions are standard and self-explanatory, following the style used elsewhere in RN. I've used `#pragma unused` to deal with parameters named by macros.
Tested by building and running the `UIExplorer` example app in XCode 8.2

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'

Summary:
On certain devices (in my case, any iPad Pro model), listening to `DeviceEventEmitter.didUpdateDimensions` would call back *before* the interface change takes places (i.e. calling `Dimensions.get()` in this callback would return wrong values). Turns out that we were listening for the wrong native event.
Edit to add: now using `[RCTSharedApplication() statusBarOrientation]` to get the current orientation. Not yet sure why, but the `userInfo` provided by the notification was returning the wrong orientation *only* on the first time you rotate the device.
