unhide MediaSyncEvent class and AudioRecord.startRecording() method with synchronization
event allowing to start audio capture upon occurence of a specific event.
So far the only event defined is playback presentation complete but more events and synchronized
playback/capture methods could be defined in the future.

o Change the impl of MediaMetadataRetriever.setDataSource(String).
It opens and passes an fd to the media framework
rather than pass the file path directly to the media server. The change is needed since media
server does not have read permission to sdcard
o Remove the unnecessary jni method

Two types of USB audio devices are defined:
- USB audio device: the audio device in USB device mode while
the Android device is in USB host mode.
- USB audio accessory: the audio device in USB host mode while
the Android device is in USB device mode.
Renamed intents for analog and digital docks to avoid confusion:
- ACTION_USB_ANLG_HEADSET_PLUG to ACTION_ANALOG_AUDIO_DOCK_PLUG
- ACTION_USB_DGTL_HEADSET_PLUG to ACTION_DIGITAL_AUDIO_DOCK_PLUG
Factorized code in AudioService broadcast receiver.

Adds flag argument to setMasterMute. This allows third parties to edit it
without showing the UI, for example.

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.

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.

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.
