Summary: Activity lifecycle events in native modules can cause exceptions: we should redbox them like we do all other application-logic triggered exceptions.

Summary: This mimics (some of) the behavior we have on iOS where if you call a JS module method before the JS bundle has started loading, we just queue up those calls and execute them after the bundle has started loading.

Summary:
There was previously a race condition where hasActiveCatalystInstance would return true, but calling a JS module call on it would result in a crash. Now, hasActivtyCatalystInstance will only return true once the instance is actually accepting calls.
I'll follow this up with a more risky diff that gets rid of hasActiveCatalystInstance and just queues JS calls until runJSBundle is called.

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: Provide a base `HeadlessJsTaskService` class that can be extended to run JS in headless mode in response to some event. Added `HeadlessJsTaskEventListener` for modules that are interested in background lifecycle events, and `HeadlessJsTaskContext` that basically extends `ReactContext` without touching it. The react instance is shared with the rest of the app (e.g. activities) through the `ReactNativeHost`.

Summary: Utilizes the build time annotation processor ReactModuleSpecProcessor that creates ReactModuleInfos for modules annotated with ReactModule and listed in the ReactModuleList annotation of LazyReactPackages. This way we don't have to instantiate the native modules to get the name, canOverrideExistingModule, and supportsWebWorkers values of the native modules. In the NativeModuleRegistry, we either store these ReactModuleInfos inside of a ModuleHolder or if we can't get the ReactModuleInfo for a specific module we instantiate that module to get the values (as we previously did) to store in a LegacyModuleInfo.

Summary:
The Android lifecycle is weird: turns out `onActivityResult` is called before `onResume`. This means `getCurrentActivity()` could return the wrong instance, or `null` if the activity was destroyed. To give developers access to the Activity receiving the result (which is also about to become the current activity), pass it as an argumento the listener.
Fixes github issue #8694.

Summary: It doesn't make sense to clear mCurrentActivity in onHostPause -- we're not going to leak a paused activity. Only keeping it around after onDestroy could lead to leaks. This allows us to check the source of lifecycle events and only send them if they come from the current activity (upcoming diff).

Summary: Fixes a race condition where JS module functions could be called in between ##initializeWithInstance(catalystInstance);## and ##CatalystInstance#runJSBundle##, before the BatchedBridge in JS was set up. We now guarantee that all JS module methods that are called after `ReactContext#hasActiveCatalystInstance()` returns true will have the batched bridge created and ready to use.

Summary:To support native modules in web workers, native modules need to have an notion of the JS executor/thread that called into them in order to respond via Callback or JS module call to the right executor on the right thread.
ExecutorToken is an object that only serves as a token that can be used to identify an executor/message queue thread in the bridge. It doesn't expose any methods. Native modules Callback objects automatically have this ExecutionContext attached -- JSModule calls for modules that support workers will need to supply an appropriate ExecutorToken when retrieving the JSModule implementation from the ReactContext.

This is an early release and there are several things that are known
not to work if you're porting your iOS app to Android.
See the Known Issues guide on the website.
We will work with the community to reach platform parity with iOS.
