nathch 842369a82b DO NOT MERGE Add stop method to backup handler thread.
Currently we call .quit() on the underlying thread which will cause all
messages to stop being processed. This has the side effect that, because
the backup system is a state machine where the state transitions are
messages, the message to transition into a state where the WakeLock is
released may not occur when a user is torn down.

This change adds a stop method we can call instead of .quit() on the
thread which drops any remaining messages and then releases the
WakeLock.

We also wrap the wakelock acquire/release calls to prevent any acquire/release on
the underlying wakelock after a quit. For the acquire, this avoids a non-released
wakelock and for the release, this avoids a runtime exception which can happen
when we release a released wakelock

This folder is for Robolectric tests inside the platform.

To add a test class annotate it as follows:

@RunWith(FrameworkRobolectricTestRunner.class)
@Config(manifest = Config.NONE, sdk = 26)
@SystemLoaderClasses({ClassUnderTest.class, DependencyClasses.class})
@SystemLoaderPackages({"com.android.server.yourmodule"})

Robolectric loads some classes that it decides from versioned jars of the framework. Since we are
part of the framework some of our classes get loaded from these jars. This is NOT what we want, we
want to test against what we wrote in the tree. Because of this we use a custom test runner,
FrameworkRobolectricTestRunner, that bypasses these jars and loads certain classes from the system
class loader.

To specify which classes to load use either @SystemLoaderClasses or @SystemLoaderPackages. In
practice:
* You MUST put the class under test here.
* If you encounter any exceptions that might be caused by a different version of the class being
loaded, such as NoSuchMethodException, put the class involved in the exception in this annotation
and try again.
