Summary:
On Android with dev mode on, we're seeing a regular SIGSEGV when pushing a lot of animation declarations over the bridge. We tracked this down to being not specific to animations, but the crash is caused in `deepFreezeAndThrowOnMutationInDev`.
Specifically: the provided object to freeze is modified while looping, replacing the current key access to a getter/setter. After the modification, JSC crashes during retrieval of the next key - but only when there are a lot of events passing over the bridge.
We have a hunch that this is due to a bug in JSC object enumeration but did we not look into it further yet. Any help here is welcome. The JS code seems all right at first sight and shouldn't cause a segmentation crash.
The workaround in this PR is to retrieve the keys first from the object and then looping over that array. In our app and in a reduced app test case this fixes the crash.
If needed I can provide the reduced app test case. It's really tricky to make a test for this as it requires to be run

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.

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.

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.

Sending global events with `eventDispatcher` has been [deprecated](d9737571c4) since 0.28, with a recommendation to subclass `RCTEventEmitter` instead, but there were no docs for this.
This updates the iOS native module to use the recommended way, and also documents the use of `stopObserving` and `startObserving`.

Summary:
Adds a high performance source map builder that has certain restrictions compared to the `'source-map'` package:
- mappings have to be in the order of the generated source
- source files have to be started/ended separately on the generator. That means building up mappings is optimized for blocks of mappings that all belong to the same source file (or no file)
The implementation avoids allocation of complex value, i.e. strings and objects as much as possible by preallocating a buffer and using numeric character values throughout. The buffer is converted to a string only at the end.
This implementation is ~5✕ faster than using `'source-map'`.

Summary:
This is step one on merging the `rnpm` config with the `cli config`. The plan is to remove two sources of truth (rnpm package.json config and rn-cli Javascript config)
Rationale:
As of now, we have `rnpm` config, that used to live in the `local-cli/core/config/index.js` and the `rn-cli` config, living in `default.config.js` and `utils/Config.js`.
This PR moves all the things into one file, called `local-cli/core', simplifies things, enhances types (Config now has better types, added missing properties and fixed descriptions).
One notable addition is that users can now opt-in to override the commands that are loaded at the package level. Previously it was only possible to add a command by writing a plugin. Now, you can just tweak the `rn-cli.config.js`.
This is one of the several improvements I have on my roadmap, with better documentation for the CLI as well.

Summary:
Currently, while running `react-native run-android` command, React Native's packager is launched, and there is not any way to disable the current behaviour. This is handled somehow on iOS by adding an environment variable `RCT_NO_LAUNCH_PACKAGER` (see #6180).
This is a cross-platform solution that adds the `--no-packager` option both to `run-ios` and `run-android`, which prevents the packager from being launched.
This was tested by building with and without the option, on both environments (Android and iOS) using the device and simulator, working as expected.

Summary:
Hello,
This PR adds a property to the `ListView` to enable and disable to sticky sections headers behaviour. Current this is enabled by default and there is no way to disable it. It has been previously discussed in #1974 where there was a suggestion to add the `ListView` inside `ScrollView`. This is bad for performance, but some people were using that as a workaround. satya164 suggested someone submitting a PR, which is why I'm here 😉
I have tested the property manually by adding `stickySectionHeaders={false}` to the `<ListView> Paging` example in `UIExplorer`. I have also tested that the current behaviour still stands, so this is a non-breaking change.
I have also checked that the website displays the new documentation.
I couldn't see anywhere to add automated tests to this, but if there is feel free to point it out and I'll update this PR.
I tried running `npm run lint` to check the code style, but it spat out loads and loads of errors. I presume I have something set up incorrectly. Feel

Summary:
I see there is a string matching inconsistency in `Libraries/CustomComponents/Navigator/Navigator.js` and `Libraries/CustomComponents/Navigator/NavigatorSceneConfigs.js`, which caused a bug resulting in gestures not working for vertical SceneConfigs. This PR fixes the inconsistency, and the bug.
**Motivation for making this change**
When working with the navigator, I was using the `VerticalUpSwipeJump` Navigator SceneConfig. The gesture to pop to the previous scene (in this case `jumpBack`) was not working.
**How I tested?**
I changed these strings (as shown in this PR) and swiped down. After these changes, everything worked as expected.
**Example**
In `Libraries/CustomComponents/Navigator/Navigator.js`, we check for gesture direction strings `bottom-to-top` and `top-to-bottom` in multiple places, but nowhere do we ever check for `up-to-down` and `down-to-up`.
```
var isTravelVertical = gesture.direction === 'top-to-bottom' || gesture.direction === 'bottom-to-top';

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'
