API addition: The timestamps are represented as nanoseconds from some
arbitrary time point. Like the SurfaceTexture transform matrix, the
timestamp retrieved by getTimestamp is for the last frame sent to the
GL texture using updateTexImage().
Camera HAL change: Expect vendors to set these timestamps using
native_window_set_buffers_timestamp(). For now, they are
autogenerated by SurfaceTextureClient if set_buffers_timestamp() is
never called, but such timing is likely not accurate enough to pass a
CTS test.

Replaced VelocityTracker with a faster and more accurate
native implementation. This avoids the duplicate maintenance
overhead of having two implementations.
The new algorithm requires that the sample duration be at least
10ms in order to contribute to the velocity calculation. This
ensures that the velocity is not severely overestimated when
samples arrive in bursts.
The new algorithm computes the exponentially weighted moving
average using weights based on the relative duration of successive
sample periods.
The new algorithm is also more careful about how it handles
individual pointers going down or up and their effects on the
collected movement traces. The intent is to preserve the last
known velocity of pointers as they go up while also ensuring
that other motion samples do not count twice in that case.

Bug #4092053
The problem always existed but was made visible by partial invalidation.
When saving a layer, the renderer would try to postpone glClear()
operations until the next drawing command. This however does not work
since the clip might have changed. The fix is rather simple and
simply gets rid of this "optimization" (that turned out to be
usless anyway given how View issues saveLayer() calls.)
This change also fixes an issue with gradients (color stops where
not properly computed when using a null stops array) and optimizes
display lists rendering (quickly rejects larger portions of the
tree to avoid executing unnecessary code.)

* commit '75c95e9a6d5a91b660af62f72b5a3bac0f5c3811':
UsbManager: Hide APIs not needed for USB host or accessory support.
Remove MtpClient class from framework and public API
UsbDevice: Move IO related methods to new UsbDeviceConnection class
UsbDevice is now just an immutable parcelable object like UsbInterface and
UsbEndpoint.
All IO related functionality is now contained in UsbDeviceConnection
and UsbRequest.

This change fixes the stability problems experienced when using
a bluetooth headset supporting both A2DP and SCO. Problems occur
when starting the video chat at which time the A2DP output is being
stopped to start SCO. At that time, active AudioTracks are invalidated
by AudioFlinger so that a new AudioTrack binder interface can be
recreated by the client process on the new mixer thread with correct parameters.
The problem was that the process to restore the binder interface was not
protected against concurrent requests which caused 2 binder interfaces
to be created sometimes. This could lead to permanent client deadlock
if one of the client threads was waiting for a condition of the first
created binder interface while the second one was created (as the AudioFlinger
would only signal conditions on the last one created).
This concurrent request situation is more likely to happen when a client
uses the JAVA AudioTrack as the JNI implementation uses simultaneously the
native AudioTrack callback and write push mechanisms. By doing so, the code
that checks if the binder interface should be restored (in obtainBuffer()) is
much more likely to be called concurrently from two different threads.
The fix consists in protecting the critical binder interface restore phase
with a flag in the AudioTrack control block. The first thread acting upon the binder
interface restore request will raise the flag and the second thread will just wait for
a condition to be signaled when the restore process is complete.
Also protected all accesses to the AudioTrack control block by a mutex to prevent
access while the track is being destroyed and restored. If a mutex cannot be held
(e.g because we call a callback function), acquire a strong reference on the IAudioTrack
to prevent its destruction while the cblk is being accessed.
Modified AudioTrack JNI to use GetByteArrayElements() instead of
GetPrimitiveArrayCritical() when writing audio buffers. Entering a critical section would
cause the JNI to abort if a mediaserver crash occurs during a write due to the AudioSystem
callback being called during the critical section when media server process restarts.
Anyway with current JNI implementation, either versions do not copy data most of the times
and the criticial version does not guaranty no data copy.
The same modifications have been made to AudioRecord.

Bug #3461349
This change also fixes two bugs that prevented partial invalidates
from working with other views. Both bugs were in our EGL implementation:
they were preventing the caller from comparing the current context/surface
with another context/surface. This was causing HardwareRenderer to always
redraw the entire screen.

It's legal to call unlinkToDeath() *after* receiving binderDied(),
as long as the recipient being unlinked was in fact linked
previously. Don't throw an exception in this case. (The
exception was going unhandled in the system process, bringing
down the runtime. That's bad.)
The change here is a bit subtle. In the new implementation, the
lifetime of a JavaDeathRecipient -- the fundamental bridge between
IBinder objects and the Dalvik/JNI world -- is tied to the
lifetime of the Dalvik-side BinderProxy object it's associated
with. That means it's inappropriate for the JavaDeathRecipient
to disappear [for purposes of being referenced from the Dalvik
side] just because the IBinder has sent out its obituaries, and
instead the JavaDeathRecipient objects are kept around until
the Dalvik-side client code actually drops its reference to the
BinderProxy.
This boils down to a one-line change: we no longer unpin the
JavaDeathRecipients and free them immediately in response to
binderDied().
The rest of the CL is #ifdefed-out debugging that is invaluable
when bugs crop up.

A local reference is obtained to the string class for the purpose of
using it later in another routine to create string object arrays.
However, the local reference is invalid by the time it is next used.
Making the string class reference a global reference eliminates the
problem.

Added some plumbing to enable the policy to intercept motion
events when the screen is off to handle wakeup if needed.
Added a basic concept of an external device to limit the scope
of the wakeup policy to external devices only. The wakeup policy
for internal devices should be based on explicit rules such as
policy flags in key layout files.
Moved isTouchEvent to native.
Ensure the dispatcher sends the right event type to userActivity
for non-touch pointer events like HOVER_MOVE and SCROLL.
