Summary:
== What ==
Changing the `JSBundleLoader` API, to remove `String getSourceUrl()`, instead `JSBundleLoader.loadScript` now returns the source URL it loaded.
This change has a knock-on effect: We can no longer populate `SourceCodeModule` when we construct it, because at that time, we do not know the source URL.
In order to solve this I have made the following changes:
- Added `CatalystInstance.getSourceURL()`, to return the source URL from the instance after the JS Bundle has been loaded, or `null` otherwise.
- Removed `ReactInstanceManager.getSourceUrl()`, because its only purpose was to populate `SourceCodeModule`.
- Also removed `ReactInstanceManager.getJSBundleFile()` because it was only being used in a test confirming that the `ReactInstanceManager` knew its bundle file as soon as it was constructed, which is no longer necessarily true.
- Initialise `SourceCodeModule` with the `ReactContext` instance it belongs to.
- Override `NativeModule.initialize()` in `SourceCodeModule` to fetch the source URL. When the `SourceCodeModule` is constructed, the context does not have a properly initialised `CatalystInstance`, but by the time we call initialise on it, the `ReactContext` has a `CatalystInstance` and that in turn has a source URL.
== Why ==
The reason for this change is that it allows us to add implementations of `JSBundleLoader`, that cannot determine their source URL until after having performed a load successfully. In particular I plan to introduce `FallbackJSBundleLoader` which will try to load from multiple sources in sequence stopping after the first successful load. As load failures could happen for a variety of reasons, we can't know what the true source URL is without performing the load.

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:
If a paused activity is destroyed (e.g. because of resource contention), we send onHostDestroyed to all modules even if there's an on-screen, resumed activity using the current react instance.
This diff adds a check to make sure lifecycle events come from the current activity, and ignores ones that don't.

Summary:
This is a follow up of the work by brentvatne in #5052. This addresses the feedback by astreet.
- Uses ReactChoreographer with a new callback type
- Callback dispatch logic moved to JS
- Only calls into JS when needed, when there are pending callbacks, it even removes the Choreographer listener when no JS context listen for idle events.
** Test plan **
Tested by running a background task that burns all remaining idle time (see new UIExplorer example) and made sure that UI and JS fps stayed near 60 on a real device (Nexus 6) with dev mode disabled. Also tried adding a JS driven animation and it stayed smooth.
Tested that native only calls into JS when there are pending idle callbacks.
Also tested that timers are executed before idle callback.
```
requestIdleCallback(() => console.log(1));
setTimeout(() => console.log(2), 100);
burnCPU(1000);
// 2
// 1
```
I did *not* test with webworkers but it should work as I'm using executor tokens.

Summary:
Implement a handler to allow intercepting all RN redboxes in Android, including exceptions in both JS and Java.
The handler is not open sourced, so there is only an open-source interface called **RedBoxHandler** in //fbandroid/java/com/facebook/catalyst/js/react-native-github/ReactAndroid/src/main/java/com/facebook/react/devsupport//, meantime there is an internal class called **FBRedBoxHandler**, which implements **RedBoxHandler** and is located in //fbandroid/java/com/facebook/fbreact/redboxhandler//, actually handles the exception information.
The code structure is as follows:
- **AdsManagerActivity** has a member variable of **FBRedBoxHandler**.
- **AdsManagerActivity** passes this handler all the way down to the **DevSupportManagerImpl**, through** ReactInstanceManager**, **ReactInstanceManagerImpl**, **DevSupportManagerFactory**.
- **DevSupportManagerImpl** intercepts the exceptions just before showing the redboxes, like this:
mRedBoxDialog.setExceptionDetails(message, stack);
mRedBoxDialog.setErrorCookie(errorCookie);
if (mRedBoxHandler != null) {
mRedBoxHandler.handleRedbox(message, stack);
}
mRedBoxDialog.show();
By now, the internal class just prints information for each redbox to logcat, including exception message and stack trace.

Summary:
public
The `DialogModule` requires `android.support.v4.app.FragmentManager` which means
every app that wants to use Dialogs would need to have its Activity extend the legacy
`android.support.v4.app.FragmentActivity`.
This diff makes the `DialogModule` work with both the Support `FragmentManager`
(for AdsManager & potentially other fb apps) and the `android.app.FragmentManager`
(for new apps with no legacy dependencies).
Also wrap the native module in the same `Alert` API that we have on iOS and provide
a cross-platform example. In my opinion the iOS Alert API is quite nice and easy to use.
We still keep `AlertIOS` around because of its `prompt` function which is iOS-specific
and also for backwards compatibility.

Summary: Change the following classes into interfaces, with a separate
Impl file: CatalystInstance, ReactInstanceManager,
CatalystQueueConfiguration, MessageQueueThread. This is done to help
isolate the interface between React Native and applications which use it.
This will also help some intrusive development work on a branch
such as porting parts of the bridge to common C++ code, without affecting
app reliability while this work is ongoing.

Summary: Automatically starts loading the RN instance as soon as loadApp is called instead of waiting for the UI to be constructed and attached to the window. This saves ~75ms of cold start time on GN 2011 phones.
Also, updates the contract for createReactContextInBackground such that it is only called once (so that people don't accidentally initialize more than once).

Summary: This patch adds two pieces of functionality:
- Exposes `JSBundleLoader` to allow a developer to load JavaScript bundles as they choose.
- Adds `ReactBridge.loadScripFromFile` method which loads a JavaScript bundle from an arbitrary file path.
Example usage:
```
JSBundleLoader jsBundleLoader = new JSBundleLoader() {
Override
public void loadScript(ReactBridge reactBridge) {
reactBridge.loadScriptFromFile("/sdcard/Download/index.android.bundle");
}
};
mReactInstanceManager = ReactInstanceManager.builder()
.setApplication(getApplication())
.setJSBundleLoader(jsBundleLoader)
.setJSMainModuleName("") /* necessary due to TODO(6803830) */
.addPackage(new MainReactPackage())
.setInitialLifecycleState(LifecycleState.RESUMED)
.build();
```
