Fix stale data due to stopped loader.
Bug 33185424
When stopping an CursorLoader while data is being loaded,
the load task will be canceled. This CL marks the data as
changed if the cancel is called while the loader is stopped.

Isolate calls to each remote DocumentsProvider.
All background work is going through AsyncTasks, which uses a shared
thread pool. Even with the new ContentProviderClient logic to detect
ANRs, the UI can still appear to be unresponsive for 20 seconds, even
if the user attempted to switch to a different backend. In the worst
case, a backlog of thumbnail requests would end up wedging Loaders
for a long time, since they all share the same THREAD_POOL_EXECUTOR.
This change isolates calls to each provider onto their own thread,
which they're free to wedge and recover from over time.
It also means we no longer need a dedicated thread pool for recents
loading, and can use a simpler Semaphore instead.
Disables thumbnails in recents on svelte devices.

Fix a bug where we could lose a loader content change.
If AsyncTaskLoader starts a background update due to a
content change, and that update is cancelled, we drop the
data when it finally arrives and forget that the content changed.
If we later come back to the loader, we then end up showing
stale data because we don't know that we still need to update
due to the old content change.
This change adds a couple new APIs to Loader to deal with the
time between when you ask for whether there is a content change
and finally either commit the data or cancel the update.
AsyncTaskLoader is changed to make use of this so that it doesn't
lose changes.

Fix cursor window leak when query execution fails.
Ensure that the Cursor object is closed if a query on a
content provider fails due to an error or is canceled during
execution. There are several places in the code where
similar problems can occur.
To further reduce the likelihood of leaks, close the cursor
window immediately when a query fails.

Implement a cancelation mechanism for queries.
Added new API to enable cancelation of SQLite and content provider
queries by means of a CancelationSignal object. The application
creates a CancelationSignal object and passes it as an argument
to the query. The cancelation signal can then be used to cancel
the query while it is executing.
If the cancelation signal is raised before the query is executed,
then it is immediately terminated.

Fix issue #3381489: IllegalStateException: attempt to re-open...
...an already-closed object: android.database.sqlite.SQLiteQuery
It turns out there is a state we are missing -- the loader is
still needed, but in the inactive list. In this case the loader
needs to continue holding on to its current data, and not deliver
any new data (which would result in it releasing its old data).
This introduces the new state to Loader, and uses it in
AsyncTaskLoader so all subclasses of that should get the new
correct behavior.
A further improvement would be to unregister CursorLoader's
content listener when going in to this state, but that can
wait for later.

Maybe fix issue #3093599: java.lang.IndexOutOfBoundsException...
...Invalid index 0, size is 0 at
android.app.ActivityThread.performPauseActivity(ActivityThread.java:2326)
It looks like if an arrow key is dispatched between the time the
list view is told its data set has changed and it does the resulting
layout pass, we could try to move the position to a now invalid
index. This may prevent that from happening.
Also put in a better error message if saving state of a fragment
whose target is no longer in the fragment manager.
And fix a bug in PackageManager where we could return a null from
queryIntentActivities().
And add a new API to find out whether a fragment is being removed,
to help fix issue #3306021: NPE at
android.app.AlertDialog.getDefaultDialogTheme(AlertDialog.java)
Next, for new HC apps we can delay committing data to
storage until the activity is stopped.
Finally, use the new multi-threaded AyncTask executor in a few
places, so we don't have worked blocked by long-running tasks from
the application.

Hiding the AsyncTaskLoader.waitForLoader method
I introduced this method a couple of weeks ago,
but then we had a chat with Dianne and she made
a good point that rather than having this behavior
on AsyncTaskLoader, we should have it on LoaderManager
and then it will cover all kinds of loaders,
not just the ones inheriting from AsyncTaskLoader.
She suggested that we postpone that work until
after Honeycomb.

Fixed the waitForLoader method.
The reason we need a separate latch is that
AsyncTask will post onPostExecute/onCancelled
_after_ executing mFuture.get(). The previous
implementation would only wait for mFuture.get()
to complete and not the entire task.

Implement issue # 3255887 could CursorLoader offer...
...to throttle contentobserver-based requeries
Why yes, I guess it could.
This also reworks AsyncTaskLoader to not generate multiple
concurrent tasks if it is getting change notifications before
the last background task is complete.
And removes some of the old APIs that had been deprecated but
need to be gone for final release.
And fixes a few little problems with applying the wrong theme
in system code.
