Added APIs to control pre processes applied on captured audio.
Those APIs are still hidden until reviewed by API council.
Three types of standard pre processes are supported:
- Automatic Gain Control (AGC) by AutomaticGainControl class
- Acoustic Echo Cancellation (AEC) by AcousticEchoCanceler class
- Noise Suppression (NS) by NoiseSuppressor class
A method is added to AudioEffect class to query audio pre processings
applied by default by the platform on a given AudioRecord session ID.

SurfaceMediaSource operates in metadata mode only, i.e. just the
metadata is stored in videobuffers. SurfaceMediaSource passes the Gralloc
buffer handle along with a 4 byte 'type' (indicating that the metadata
is of type GrallocSource) to the encoder as opposed to the
GrallocBuffer itself.

The Surface is already using SurfaceTexture internally and it is parcelable. This
is intended to replace and phase out ParcelSurfaceTexture in favor of creating a
new Surface.java object from an existing SurfaceTexture.

This change removes support for conditionally using the GL_TEXTURE_2D
target for SurfaceTexture textures with RGB buffers. It also enables
and fixes the RGB-based SurfaceTexture tests.

Restore QueryCodecs() signature exactly as used by third-party libs.
Add an alternative function to select HW only codecs.

This change adds the 'abandon' method to the SurfaceTexture C++ class.
This method may be used to put the SurfaceTexture in an abandoned state,
causing all ISurfaceTexture methods to fail.

Making a connection from MediaRecorder Native layer to the
SurfaceMediaSource for the purpose of encoding GL Frames. This will be
called from the java side inside the Mobile Filter Framework.
The mediarecorder native layer (client), when set the videosource to
option VIDEO_SOURCE_FRAMES, asks the StageFrightRecorder on the mediaserver
side to create a SurfaceMediaSource object and pass it back as a
sp<ISurfaceTexture> object. Using that, the client side will dequeue and
queue buffers. Connecting the GL Frames to the obtained
sp<ISurfaceTexture> is not part of this CL.

This change removes the getAllocator method from SurfaceMediaSource
because that method is no longer a part of the ISurfaceTexture
interface.

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.

Adding an enum to indicate an android opaque OMX
colorformat. This will inform the encoder that
the actual colorformat will be relayed by the
Frames read from the GRAlloc Buffers

This change removes the SurfaceTexture::getAllocator method, as it's no
longer needed. Proper refcounting of the Gralloc buffers is now handled
by the IGraphicBufferAlloc binder marshalling code.

Add an option to OMXCodec::QueryCodecs() to filter out
software codecs.
Update stagefright command line tool to list the roles of codecs.

Audio effect framework is extended to suport effects on
output and input audio path.
AudioFlinger: Support for audio effects and effect chains is
moved from PlaybackThread class to ThreadBase class so that
RecordThread can manage effects.
Effects of type pre processing are allowed on record thread
only. When a pre processing is enabled, the effect interface handle is
passed down to the input stream so that the audio HAL can call the
process function. The record thread loop calls the effect chain process
function that will only manage the effect state and commands and skip the
process function.
AudioRecord: The audio session is allocated before calling getInput() into
audio policy serice so that the session is known before the input theead is
created and pre processings can be created on the correct session.
AudioPolicyService: default pre processing for a given input source are
loaded from audio_effects.conf file.
When an input is created, corresponding effects are created and enabled.

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