First drop of audio framework modifications for audio effects support.
- AudioTrack/AudioRecord:
Added support for auxiliary effects in AudioTrack
Added support for audio sessions
Fixed left right channel inversion in setVolume()
- IAudioFlinger:
Added interface methods for effect enumeraiton and instantiation
Added support for audio sessions.
- IAudioTrack:
Added method to attach auxiliary effect.
- AudioFlinger
Created new classes to control effect engines in effect library and manage effect connections to tracks or
output mix:
EffectModule: wrapper object controlling the effect engine implementation in the effect library. There
is one EffectModule per instance of an effect in a given audio session
EffectChain: group of effects associated to one audio session. There is one EffectChain per audio session.
EffectChain for session 0 is for output mix effects, other chains are attached to audio tracks
with same session ID. Each chain contains a variable number of EffectModules
EffectHandle: implements the IEffect interface. There is one EffectHandle object for each application
controlling (or using) an effect module. THe EffectModule maintians a list of EffectHandles.
Added support for effect modules and effect chains creation in PlaybackThread.
modified mixer thread loop to allow track volume control by effect modules and call effect processing.
-AudioMixer
Each track now specifies its output buffer used by mixer for accumulation
Modified mixer process functions to process tracks by groups of tracks with same buffer
Modified track process functions to support accumulation to auxiliary channel

Add more error checking for ndc
Add javadoc for camera scene modes.
more clean-up in preparation of bigger changes
Fix a typo in Singleton<>
Avoid copying for input recording frames in CameraSource
Add video frame parameter.
more clean-up of Surfaceflinger's client management
Better sniffing of MPEG4 content by checking for a compatible sub-brand.
Remove the logic in CameraSource using CameraParameters class to find out the buffer size.
Add support for gps altitude EXIF tags.
minor clean-up GLclampx -> GLclampf
clean-up dead-code
Make sure to use filtering while in fixed-size mode
oopsie. forgot to displatch SET_BUFFERS_GEOMETRY
Avoid repeatedly allocating and freeing memory in CameraSource
After failing to create an AudioTrack, only stop the source if we were the ones starting it.
Convert a number of assertions into runtime errors (OggExtractor)
fix [2712278] The preview buffer left some black borders in left and bottom edges
Fix 2667859: change text back to default size
Support for thumbnail extraction in the Matroska extractor.
...
opaque 32-bits windows are now allocated as RGBX_8888 buffers and
SurfaceFlinger always uses GL_MODULATE instead of trying to
optimize to GL_REPLACE when possible (makes no sense on
h/w accelerated GL).
we still have a small hack for devices that don't support
RGBX_8888 in their gralloc implementation where we revert to
RGBA_8888.

SurfaceComposerClient now only exist on the WindowManager side,
the client side uses the new SurfaceClient class, which only
exposes what a client needs.
also instead of keeping mappings from IBinder to SurfaceComposerClients
we have a SurfaceClient per Surface (referring to the same IBinder), this
is made possible by the fact that SurfaceClient is very light.
