From recent feedback on HDMI-CEC system audio mode,
it would be unnecessary to enforce output from AudioService.
Instead, it would follow audio policy according to status
of HDMI-CEC system audio mode.
For that removed two params of setHdmiSystemAudioModeSupported
api of AudioManager.
In terms of speaker mute, it will be handled by removing speaker
from audio ouput instead of changing gain control. For that
added new force usage type, FOR_HDMI_SYSTEM_AUDIO_MODE and
new force config type, FORCE_HDMI_SYSTEM_AUDIO_ENFORCED.
This is used to notify change of system audio mode to
audio policy manager.

In previous change we use setForceUse(FORCE_MEDIA, XXX) method
in order to set specific audio output type, such as LINE, HDMI_ARC,
and SPDIF. But it turns out that it conflicts with bluetooth
a2dp which uses the same setForceUse(FORCE_MEDIA, yyy).
This change is based on several conditions.
1. When other non-speaker devices are on, prevent system audio
from turing on.
2. In order to keep track of other devices' connectivity and to
turn off system audio if other device like bluetooth or
headphone preempts current output, register OnAudioPortChangeListner
to audio manager.
3. All possible system audio outputs can be merged with other
outputs without priority.

Hdmi-Cec's system audio mode delegates audio control to
audio receiver from tv. It requires to delegate
volume change including mute to audio receiver
instead of consuming by tv.
In order to do this this change introduces three apis.
One is added to IAudioService, the others are added
to IHdmiControlService as hidden apis.
1. IAudioService#setHdmiSystemAudioSupported;
This is to notify system audio mode change to audio
service so that it determines to notify volume or mute
change to HdmiControlService.
2. IHdmiControlService#setSystemAudioVolume;
This is to notify volume change to HdmiControlService.
It's called only where system audio mode is on.
3. IHdmiControlService#setSystemAudioMute;
This is to notify volume change to HdmiControlService .
It's called only where system audio mode is on.

There's a longer term plan to fix audio/video sync, but
this gets the Java level to parity with the native level,
and allows applications in Java to achieve sync in the
same way as the native media player. APIs are left as hidden
for now.

Use mcc config overlay mechanism to enforce camera shutter sounds
in countries where it is mandatory.
Property ro.camera.sound.forced is not needed anymore.
When camera sound is forced, STREAM_SYSTEM_ENFORCED is removed from
streams affected by ringer mode and its volume is
maxed out. AudioSystem.FORCE_SYSTEM_ENFORCED is sent to audio
policy manager to alter the routing policy for STREAM_SYSTEM_ENFORCED.
Also fix streams being unmuted when settings are reloaded
upon user switch while in silent mode.
Add ringer mode to audio service dump.

remote submix will:
- make the sink audio device available/unavailable
- make the audio source available/unavailable

Clean up related to new Vibration policy.
The vibrate behavior is now only derived from:
- presence of a vibrator on the device
- current ringer mode selected: NORMAL, VIBRATE or SILENT
If no vibrator is present the ringer mode can only be NORMAL or SILENT.
The control of ringer mode via volume keys when volume keys control the "master"
stream type (RING on phones, MUSIC on tablets) is as follows:
If a vibrator is present:
VOL- and volume equals 1: NORMAL => VIBRATE
VOL- and volume equals 0 and not continuous press: VIBRATE => SILENT
VOL+ and in SILENT mode: SILENT => VIBRATE
VOL+ and in VIBRATE mode: VIBRATE => NORMAL, volume = 1
If no vibrator is present:
VOL- and volume equals 0 and not continuous press: NORMAL => SILENT
VOL+ and in SILENT mode: SILENT => NORMAL, volume = 0
VIBRATE_ON and VIBRATE_IN_SILENT settings are not stored/retreived any more.
AudioService checks and corrects ringer mode and stream volumes if necessary when reading from
DB at boot time.
Also:
Added dump for stream volumes in AudioService.
Added device names missing in AudioSystem for USB accessory and USB device.

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

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.

Releases prior ICS (included) would persist the stream volumes in the
database when muted by silent mode. If the DB was backed up while in
silent mode, stream volume was backed up at 0.
When restored on a new device, the volume was restored at 0 which was
a problem for SYSTEM stream because it would never be corrected as
this stream volume is fixed.
Added a check on valid volume values when reading settings from the DB
and correct the DB if this happens.

Improve volume management by keeping track of volume for each type
of device independently.
Volume for each stream (MUSIC, RINGTONE, VOICE_CALL...) is now maintained
per device.
The main changes are:
- AudioService now keeps tracks of stream volumes per device:
volume indexes are kept in a HashMap < device , index>.
active device is queried from policy manager when a volume change request
is received
initalization, mute and unmute happen on all device simultaneously
- Settings: suffixes is added to volume keys to store each device
volume independently.
- AudioSystem/AudioPolicyService/AudioPolicyInterface: added a device argument
to setStreamVolumeIndex() and getStreamVolumeIndex() to address each
device independently.
- AudioPolicyManagerBase: keep track of stream volumes for each device
and apply volume according to current device selection.

- Add comment to stream_type, audio_mode, force_use types that they must match
values in AudioSystem.java.
- Add comment about unused types mp3_sub_format and vorbis_sub_format.

- Use @ in javadoc comments.
- Delete dead APIs setMode, getMode, setRouting, getRouting in AudioSystem.java
