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.

createTrack and openRecord don't need the "old" flags parameter,
which was either audio_policy_output_t or audio_in_acoustics_t
shifted left by 16 bits. But they do need "new" flags, which
are defined by the application use case. Initially, the only
application use case flag is timed output, but others are planned.
For output, the audio_policy_output_t flags are passed to
AudioSystem::getOutput, which returns an audio_io_handle_t, and that
handle is then passed to createTrack. So createTrack doesn't need the
old flags parameter.
For input, the audio_in_acoustics_t flags are passed to
AudioSystem::getInput, which returns an audio_io_handle_t, and that
handle is then passed to openRecord. So openRecord doesn't need the
old flags parameter.

MediaRecorder.setPreviewDisplay() is not required if applications
use MediaRecorder.setCamera(). Besides, this causes a problem when
apps use Camera.setPreviewTexture. Camera service thinks the
surface texture from Camera.setPreviewTexture and the surface from
MediaRecorder.setPreviewDisplay are different.
