o made all the member variables in helper classes for TimedText to be public and final
since they are read-only
o removed Text and TextPos helper classes
o added two public methods in TimedText class: getText() and getBounds()
o cleaned up the javadoc of related methods in MediaPlayer.java and TimedText.java classes
o make the inner classes of TimedText static and final
o change invoke and let it throw RuntimeException on failure (thus a test class needs to be
modified also).

Introduce IRingtonePlayer, which handles playback for both Ringtone
objects and Notifications. SystemUI now hosts this player, which it
registers with AudioService. It also keeps MediaPlayer instances
warm, and cleans them up after stop() or Binder death.
Move both Ringtone and NotificationManagerService to play back audio
through this new interface.

Implement a more consistent policy for system and UI sounds (key clicks, lock/unlock,
camera shutter, DTMF, low battery...):
- All system sounds are played over STREAM_SYSTEM stream type.
- The STREAM_SYSTEM volume that was previously fixed now tracks the volume of a "master"
stream type. This "master" stream type is STREAM_RING for phones and STREAM_MUSIC for
tablets which corresponds to the stream whose volume is modified by default by the volume
keys.
- The STREAM_SYSTEM volume ranges from -24dB to -6dB (-24dB to -12dB over headphones) when the
"master" stream volume ranges from its min to its max.
- DTMF tones are played over STREAM_DTMF that tracks the "master" stream volume in the same
manner with the following exception: when in call, DTMF stream tracks STREAM_VOICE_CALL volume.
- Camera shutter sound is played over STREAM_SYSTEM_ENFORCED stream that tracks the "master"
stream volume except in countries where regulation enforces this sound. In this case
its volume is fixed and cannot be muted.
- Low battery sound is played over STREAM_SYSTEM and therefore has a tunable volume and is
heard while in call.

AudioManager.forceVolumeControlStream() is used by VolumePanel to temporarily force the
stream type which volume is controlled by volume keys.
Current implementation is not working if the VolumePanel is not executed by the same process
as the one receiving the volume key events.

Previously when processing playlists, the entire audio table would be read for
every line in a playlist file. While there would be only one query, a lot of
data was being moved from sqlite to java over and over again, and if the data
didn't all fit in a CursorWindow, additional queries would be done under the
hood.
With this change, playlists are first cached in memory. Then the audio table
is queried, and for every row in the audio table, the best match from the
playlist cache is found. This way the audio table is only traversed once,
so each row is only fetched once. Once the entire audio table has been read,
the in-memory playlist cache contains the best matching entry for each line,
and the playlists are written out to the database. Currently, the audio table
is traversed once for each playlist. This could be further optimized in the
future by processing all playlists at the same time.

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

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
