Add a destroyOMXPlugin() to complemenet createOMXPlugin(). Since the latter is
an opaque call into a library, it is not safe to assume that the object thus
returned may be destroyed by calling delete. This patch will call
destroyOMXPlugin() in libstagefrighthw.so, if the symbol is defined there.
Otherwise, it will default to a delete as before.
Also, prefer C linkage for the symbol names. Using mangled C++ symbols is not
very safe and makes it hard to grep for those symbols through the code. We
attempt to locate createOMXPlugin as a C symbol then try it as a mangled C++
one. We only use C linkage for destroyOMXPlugin since this symbol is new.

AudioRecord::getInput() was issuing a query to get a new input stream from
audio policy service instead of returning the cached input stream in AudioRecord.

For using the MediaRecorder in MFF (Mobile Filter Framework),
getMediaRecorder method in mediarecorder jni was earlier changed to
a non static method. Changed it back to a static method.
Also, added a new source type to MediaRecorder.VideoSource for recording
GRalloc buffers.

When creating a new AudioTrack instance, translate from a Java
channel mask as defined in android.media.AudioFormat to one
as defined in audio.h which matches industry-standard
channel mask definitions.

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.

Add definitions for the side and elevated channels.
Add new (correct) definition for 7.1 mask which uses
the side channels rather than the front half-pan channels.

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.

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.
