Instead of sending finished signals immediately when appending to
a batch, record the chain of sequence numbers that were part of
the batch and then send finished signals all at once when done.
This change helps the dispatcher keep track of the true state
of the application and can improve ANR detection slightly.
This is part of a series of changes to improve input system pipelining.

Add support for modifying the playback rate of a MediaPlayer
by altering the sample rate of its AudioTrack.
The playback rate is expressed in permille, where 1000 is the
playback at normal speed.

To support this feature, the input dispatcher now allows input
events to be acknowledged out-of-order. As a result, the
consumer can choose to defer handling an input event from one
device (because it is building a big batch) while continuing
to handle input events from other devices.
The InputEventReceiver now sends a notification when a batch
is pending. The ViewRoot handles this notification by scheduling
a draw on the next sync. When the draw happens, the InputEventReceiver
is instructed to consume all pending batched input events, the
input event queue is fully processed (as much as possible),
and then the ViewRoot performs traversals as usual.
With these changes in place, the input dispatch latency is
consistently less than one frame as long as the application itself
isn't stalled. Input events are delivered to the application
as soon as possible and are handled as soon as possible. In practice,
it is no longer possible for an application to build up a huge
backlog of touch events.
This is part of a series of changes to improve input system pipelining.

Since we will not longer be modifying events in place, we don't need
to use an ashmem region for input. Simplified the code to instead
use a socket of type SOCK_SEQPACKET.

Services now must explicitly opt in to being accessed by isolated
processes. Currently only the activity manager and surface flinger
allow this. Activity manager is needed so that we can actually
bring up the process; SurfaceFlinger is needed to be able to get the
display information for creating the Configuration. The SurfaceFlinger
should be safe because the app doesn't have access to the window
manager so can't actually get a surface to do anything with.
The activity manager now protects most of its entry points against
isolated processes.

Other:
- add a comment to nextUniqueId
- made ThreadBase::mId const, since it is only assigned in constructor.

This patch allows us to automatically detect whether ctts box is needed in MPEG4Writer.
MPEG4Writer uses ctts version 0 (non-negative offset value) store the composition time
offset on a needed basis.
Currently, the size of the ctts box is not optimized. Optimization will be addressed
in a subsequent patch.
o also changed the private method retrieveDecodingTime(bool) in OMXCodec
to getDecodingTime()

This adds basic support for clip regions. It is currently disabled at compile
time. Enabling clip regions will require setting up a stencil buffer.

Fortunately audio_track_cblk_t doesn't have a destructor, but for clarity
remove the double destruction.
Also add warning not to add any virtuals to audio_track_cblk_t.

This is just documentation, as C++ method const-ness doesn't mean anything
for a binder API. Instead, here const means "no side effects".

Have not found any concrete bugs related to these calls yet, but we should avoid
calling virtual functions in destructors, regardless.

The client callback threads had mutexes called AudioTrackThread::mLock
and ClientRecordThread::mLock. These mutexes were only used by start()
and stop(), and were unused by the thread itself. But start() and
stop() already have their own protection provided by AudioTrack::mLock
and AudioRecord::mLock. So the thread mutexes can be removed.

with this changes, SF transactions are handled as soon as possible
but do not trigger updates. the update is delayed until the next
vsync.
this allows us to work much better without requiring triple-buffering.

vsync events were sometimes delivered to connected
client who didn't request them. this happened if
another client requested the delivery and that client
was first in the client list.
also fix the vsync test which didn't request any events as
well as DisplayEventReveiver documentation which was misleading
about the necessity to request vsync events.

In our current environment with very many translations, this can
save a lot of RAM -- for example over 200K in Gmail just by sorting
the strings in the Gmail .apk (not the framework).
Also add a new aapt command to print the contents of the resource
table string pool.

Also remove defaults in startToneCommand(), they're not needed and the
