You can remove sub-tasks inside of a task, or an entire task.
When removing an entire task, you can have its process killed
as well.
When the process is killed, any running services will get an
onTaskRemoved() callback for them to do cleanup before their
process is killed (and the service possibly restarted).
Or they can set a new android:stopWithTask attribute to just
have the service automatically (cleanly) stopped at this point.

We now only keep a thumbnail for the task, not for each
activity. However if you use FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET,
we will make a new secondary thumbnail for that series of
activities. There is a new API for the app to get these
secondary thumbnails.
Also set a default thumbnail size for non-xlarge screens
so we have thumbnails on phones. (We need some smarter
code in the platform for computing the actual thumbnail
dimensions of the current device). And add a test app
to show recent tasks + thumbnails.
