Added the infrastructure to support the synchronization of playback and
capture actions on specific events.
The first requirement for this feature is to synchronize the audio capture
start with the full rendering of a given audio content.
The applications can further be extended to other use cases
(synchronized playback start...) by adding new synchronization events and
new synchronous control methods on player or recorders.
Also added a method to query the audio session from a ToneGenerator.

This is part of the multi-project commit to move the filter-framework
from system/media/mca to frameworks/base/media/mca.
Note that the filter-framework will soon be replaced with a refactored
version currently under API review (also to go under frameworks/base).
This move is done now to unblock the PDK efforts.

MediaScanner sets DATE_TAKEN with EXIF's datetime tag value. When this information is not available,
ExifInterface will simply return -1 which is accidentally used by MediaScanner.
Adding a check to avoid it so MediaProvider can calculate the date taken from last modified time instead.

Current method implemented by the visualizer to detect that audioflinger has
stopped providing audio buffers does not work if the application
reads pcm captures too fast.
The fix consist in implementing a method based on real time measurement only.
One drawback is that the new method makes use of system calls that add some
overhead to the process and capture functions.

Reorganize SoundPool and JetPlayer code to be ready for the
creation of libmedia_native.
Split SoundPool between libsoundpool (JNI) and libmedia(sound pool implementation).
Remove dependencies on nativehelper/jni.h from JetPlayer.

The recent removal of the cache from MediaScanner (commit 58ef68905d67e356eb)
slowed down processing of playlists, in some cases significantly, due to every
line in a playlist prompting a query that looped over the entire audio table.
With this change, the query is only done once instead of for every line,
and the code starts iterating over the Cursor starting near the point of
the last match, instead of from the start. The latter is especially helpful
when the entire query result is too large to fit in a CursorWindow, since
it reduces the number of times that sqlite has to perform an offset query
under the hood to refil the window.

Gapless playback for appropriately tagged mp3 and m4a files.
Currently this is implemented in OMXCodec, which most players
use, but should be easy to support in other players as well by
using the SkipCutBuffer utility class.

It was only used to decide whether to issue a warning.
The warning was issued the first time track was created but
not at re-creation. Now it is a verbose message every time,
not a warning since it happens all the time with key clicks on A2DP.
