Uses a new "MTP objects" table in the media provider to support basic
enumeration of the external storage file system.
Support for accessing audio, video and image metadata in the existing
media provider tables will be added in a later commit.
The C++ MtpDatabase class is now abstract, to support a proxy subclass that
calls through JNI to the Java MtpDatabase class in the media provider.

The visualizer enables application to retrieve part of the currently playing audio for visualization purpose.
It is not an audio recording interface and only returns partial and low quality audio content as a waveform or
a frequency representation (FFT).
Removed temporary hack made in MediaPlayer for animated wall papers based on audio visualization (snoop() method.
This commit also includes a change in AudioEffect class:
- the enable()/disable() methods have been replaced bya more standard setEnabled() method.
- some fixes in javadoc

Effect API:
- Use different definitions for audio device, channels, formats... in AudioSystem and EffectApi:
Removed media/AudioCommon.h file created for initial version of EffectApi
- Indicate audio session and output ID to effect library when calling EffectCreate(). Session ID can be useful to optimize
the implementation of effect chains in the same audio session. Output ID can be used for effects implemented in audio hardware.
- Renamed EffectQueryNext() function to EffectQueryEffect() and changed operating mode:
now an index is passed for the queried effect instead of implicitly querying the next one.
- Added CPU load and memory usage indication in effects descriptor
- Added flags and commands to indicate changes in audio mode (ring tone, in call...) to effect engine
- Added flag to indicate hardware accelerated effect implementation.
- Renamed EffectFactoryApi.h to EffectsFactoryApi.h for consistency with EffectsFactory.c/h
Effect libraries:
- Reflected changes in Effect API
- Several fixes in reverb implementation
- Added build option TEST_EFFECT_LIBRARIES in makefile to prepare integration of actual effect library.
- Replaced pointer by integer identifier for library handle returned by effects factory
Audio effect framework:
- Added support for audio session -1 in preparation of output stage effects configuration.
- Reflected changes in Effect API
- Removed volume ramp up/down when effect is inserted/removed: this has to be taken care of by effect engines.
- Added some overflow verification on indexes used for deferred parameter updates via shared memory
- Added hardcoded CPU and memory limit check when creating a new effect instance

Audio sessions are used to associate audio effects to particular instances (or groups) of MediaPlayers or AudioTracks.
Change-Id: Ib94eec43241cfcb416590f435ddce7ab39a07640
Added AudioEffect C++ class. AudioEffect is the base class for effect specific implementations,
OpenSL ES effect interfaces and audio effect JNI.
Added the AudioEffect JNI and AudioEffect JAVA class. AudioEffect is the base class
to implement more specific JAVA classes to control audio effects from JAVA applications.

The problem is that we are referring an temp object returned from a function call.
When the function call returned, the temp object is gone; and thus the reference
may be invalidated.

Surfaces can now be parcelized and sent to remote
processes. When a surface crosses a process
boundary, it looses its connection with the
current process and gets attached to the new one.

this is used in a few places to get access to the android.view.Surface
native surface. use a macro instead. Also rename the field to mNativeSurface.

MediaMetadataRetriever uses a single static lock for all operations.
This effectively serializes all metadata retrieval operations in a
single process. This patch uses the object level lock for all normal
operations and only uses the static lock to serialize calls to
release.

SoundPool itself also creates a thread, which was called "SoundPoolThread", unrelated to the SoundPoolThread class. The SoundPoolThread class then created an unnamed thread, which showed up as "android:unnamed_thread". That's confusing, so this change renames the SoundPool thread to "SoundPool" and then names the SoundPoolThread thread as "SoundPoolThread". Say that ten times fast :)

- I decided to completely remove jpeg decoding related stuff from this change
I think that setting is better off if it is specified by the system properties.
We don't have to include MediaProfiles.h header in skia files
AudioTrack was modified earlier to calculate minimum buffer size
based on the hardware reported latency. Previously, it was a
hard-coded value. As a result of this change, the minimum buffer
size is now variable based on hardware latency. On Passion, this
brought out a subtle rounding error in the buffer size calculation
in SoundPool. This can cause AudioTrack creation to fail based on
the requested sample rate. This fix calculates the total buffer
size first, and then does rounding before dividing by the number
of buffers.
This currently assumes 44k stereo (won't crash on other formats, but won't give the correct results either), and links statically with libspeex to get FFT data, increasing the size of libmedia by about 45kb.
so that it can erase the data column for entries that are in the
folder containing the .nomedia file. This prevents us from
deleting (via a delete trigger) files when somebody adds a
.nomedia file after the fact.
