The problem is that the AudioService is not notified of the death of
IAudioFlinger binder interface because no methods was called on AudioFlinger
from system_server since the device booted. Therefore, AudioSystem did not created any
IAudioFlinger interface in the system_server process.
The root cause was always present but more likely to happen on a tablet than on a phone
as for instance no beeps are played when volume is adjusted.
The fix consists in having AudioSystem explicitly call a method on AudioFlinger when a
callback is installed to make sure that an IAudioFlinger binder interface is created
regardless of any other activity in the client process.

Commit 25101b0b in AudioSystem for issue 3395734 broke the mechanism
in AudioService to poll and detect the restarting of media server
process after a crash.
The fix consists in changing the method used to poll AudioSystem and
trigger a callback indicating success when media server is responding
(the method must be on IAudioFlinger and not IAudioService to trigger the callback).

- Make sure that STREAM_MUSIC is affected by ringer mode on non voice capable
devices whatever the saved settings say.
- Added a hidden method to AudioManager for VolumePanel to override
the stream selection logic while the panel is showing.

Note: dependent on external/flac for libFLAC
Implemented and tested:
* FLAC container
* mono and stereo
* standard sample rates
* standard bit depths
* sniffer
* media scanner
* Vorbis comment metadata including album art
* random access seeking with "torture test"
* web browser integration for audio/flac (not audio/x-flac), but
note that most web servers don't correctly report the MIME type
Not implemented:
* 24-bit to 16-bit dither or noise shaping in AudioFlinger
* 96 kHz to 44.1 or 48 kHz downsampling low pass filter in AudioFlinger
* replay gain is better done in AudioFlinger
* multi-channel, would need AudioFlinger support
* Ogg container, does not seem to be very popular yet

Modified default volume control logic in AudioService:
1 IN_CALL volume if in video/audio chat
2 NOTIFICATION if notification is playing or was playing less than 5s ago.
3 MUSIC
Modified silent mode:
- now also affect MUSIC stream type
- entering silent mode when VOL- hard key is pressed once while selected
stream volume is already at 0 (except for VOICE_CALL stream).
- exiting silent mode when pressing VOL+ hard key while in silent mode
Play sound FX (audible selections, keyboard clicks) at a fixed volume.
Modified audio framework:
- isStreamActive() method now implemented in AudioPolicyManagerBase (previously AudioFlinger)
- iStreamActive() now specifies a time window during which the stream is considered
active after it actually stopped.
