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: 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: Add a new interface to JSC that allows loading a file lazily from disk, i.e. using mmap, instead of loading the whole file upfront and copying into the VM.

Summary:
Found a couple of places where we were copy-pasting the logic `ResourceDrawableIdHelper` had. This class was only available on the image module and it had package visibility. I moved it to its own module so that we can easily use it from others.
This diff is pretty simillar to 54ed44628d but it fixes a bug due to which we had to revert it.

Summary:
The default priority for AsyncTask is THREAD_PRIORITY_BACKGROUND which puts the thread in a limited cgroup that can utilize ~10% CPU time. Because the whole TTI depends on this task we should run it on a normal priority.
The priority will be reset for the nest task and this has been true since donut: https://github.com/android/platform_frameworks_base/blob/donut-release/core/java/android/os/AsyncTask.java

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:
1. Make "Remote JS Debug" and "Start/Stop Profile" options persist across app restarts.
2. Check and confirm:
- All options in the Android dev menu are persisted now.
- The behavior is the same on Android and iOS now.
