Adding SurfaceEncoder which can be used to encode
custom frame data. In a sense, it is reverse
of what SurfaceTexture does.
SurfaceEncoder takes in frames from a native window and
passes them to an encoder, thus acting like a MediaSource.
It uses GRAlloc buffers underneath for passing data.
The client side sets the geometry, format in the beginning,
which cannot be changed while the recording is going on.
Currently, there is no common pixel format that both
GRAlloc and HAL understand.
Also, the encoder cannot encode using the data from the GRAlloc
buffers.
The SurfaceEncoder_test examines mainly the buffer passage
since true encoding cannot be done at this point.
SimpleDummyRecorder 'reads' the frames in the same thread
as the start(), whereas DummyRecorder 'reads' in a separate
thread much like the MPEG4Writer. The test with DummyRecorder
is much closer to the real encoding implementation.

This makes ANativeWindow_lock/ANativeWindow_unlockAndPost work
with ANativeWindows implemented by Surface and SurfaceTextureClient.
Also, Surface now inherits directly from SurfaceTextureClient.

This change makes the ANativeWindow connect and disconnect calls result
in an IPC to the SurfaceTexture object. This will allow us to prevent
multiple simultaneous connections from different processes.

This change fixes how the Android EGL layer overrides the size and
format of an ANativeWindow in eglCreateWindowSurface. The new behavior
is to leave the size untouched when overriding the format. The previous
behavior was to reset the ANativeWindow to use the default size set by
the ANativeWindow implementation.
It also adds two new 'perform' methods to the ANativeWindow interface:
set_buffers_dimensions and set_buffers_format, and redefines the
behavior of set_buffers_geometry to be the combination of these two new
methods.
Additionally, this change adds an error check for the return value of
the new native_window_set_buffers_format call, which required adding a
(stub) handler for to FramebufferNativeWindow.

Modified the touch input mapper to assign pointer ids sequentially
starting from 0 instead of using the tracking id or slot index
supplied by the driver. Applications should not depend on this
ordering but some do. (sigh)

This is intended to absorb the cost of the IPC
to the permission controller.
Cached permission checks cost about 3us, while
full blown ones are two orders of magnitude slower.
CAVEAT: PermissionCache can only handle system
permissions safely for now, because the cache is
not purged upon global permission changes.

This change alters the conditions under which the onFrameAvailable
callback gets called by the C++ SurfaceTexture class. The new behavior
is to call the callback whenever a frame gets queued that will be
visible to the buffer consumer. This means that buffers queued in
synchronous mode always trigger the callback, as those buffers will
remain pending until they are consumed. Buffers queued in asynchronous
mode will only trigger the callback if there was not previously an
unconsumed buffer pending.
The new behavior means that a consumer should perform a draw operation
exactly once for every onFrameAvailable call that it recieves. This
change also modifies SurfaceFlinger and the SurfaceTexture JNI to
support of the new behavior.

The offset that is used in the creation of the MemoryHeapBase must be saved, so
that it can be used to recreate the Heap when an IMemory object is passed
across process boundary through the binder.

This new API will be used by applications that previously used the
lower-level pthread APIs (including pthread_join). Centralizing on the
Thread class instead of pthread will permit additional functionality to
be added later in only one location.

This change moves the computation of the transform matrix out of
getTransformMatrix and instead performs the computation when
updateTexImage gets called. This is needed in order for
getTransformMatrix to succeed even if the buffers have been freed (e.g.
by changing the buffer count) because the computation depends upon the
properties of the current GraphicBuffer.

Bug: 4490420
pthread_create already includes the necessary memory barriers:
- parent at pthread_create : pthread_mutex_unlock(start_mutex)
- child at __thread_entry : pthread_mutex_lock(start_mutex)
Add lock around uses of mThread.
Added comments:
- uses of mThread require lock
- androidCreateRawThreadEtc returned ID is not safe for direct use from non-parent threads.
