PlayerProxy: more control options (pan, delayed start),
remove exceptions in method signatures.
Use delayed start on notification playback for better sync
between media apps and notifications
Disabled for now: support for AudioService (through
MediaFocusControl and PlaybackActivityMonitor) to enforce
audio ducking of focus owners losing audio focus with
AUDIOFOCUS_LOSS_TRANSIENT_CAN_DUCK, and who don't
play audio that has a content labelled as CONTENT_TYPE_SPEECH.
This feature will be enabled when setting a VolumeShaper
on a player works.

An AudioPlaybackConfiguration contains an IPlayer
interface for system control of a player. It is not
exposed to non-system signature components.
AudioService, through PlaybackActivityMonitor, is monitoring
the death of the IPlayer so the matching player can get
unregistered in case it meets its maker.
Test: use vendor/google_toolbox/team/audio/cmds/ClPlaybackActivity

AudioService keeps track of status of implementations of PlayerBase.
AudioService's PlaybackActivityMonitor maintains a list of
playback configurations for each PlayerBase, and a list
of clients that want to receive updates about the playback.
Playback activity clients can query the playback configuration
of the system through AudioManager, or register a callback
for updates. For clients with MODIFY_AUDIO_ROUTING permission
(system), the playback configurations contain more information
about each player (player type, uid, pid, state), and can see
all players, not just the "active" ones. The act of stripping
off data about the players that is not supposed to be seen
by non-system clients, is referred to as "anonymization". It
is implemented in system server, so no system data is ever
sent to playback activity clients without system permission.
More information about the AudioPlaybackConfiguration is
available in the SystemApi (uid, pid, player type, player state).

Deprecate methods where stream types are not used for
volume control operations.
Add a warning in the logs about the use of stream
types to encourage migration to audio attributes.
Since STREAM_ACCESSIBILITY is added in O for the
volume of a11y audio, throw an exception when
trying to use it for playback.

Modified the signature of the abstract volume methods so
it is clear at the subclass level whether the volume
command is for a mute or a volume control.
Changed the implementations in the subclasses
accordingly.
Removed appOps handling inside SoundPool and made it
inherit from PlayerBase.
Moved handling of the camera sound restriction from
SoundPool to PlayerBase.
Added support in SoundPool native implementation for
muting, as each player has its own volume.
Test: play a long file with SoundPool and enter DnD mode

The default sampling rate chosen for an AudioTrack or AudioRecord
constructed with a Builder not specifying a sampling rate is not
the primary output sampling rate but depends on the device actually
selected.

Add a new class to group media/audio player features under one
interface. Currently only used for audio-related AppsOps
restrictions. In the future can group routing, audio focus
handling by the framework...
MediaPlayer inherits from PlayerBase, and overrides the methods
that are needed to delegate the handling of the restrictions
in a separate class.
When AppOps restrictions change (as triggered through the
callback in PlayerBase), reset the volume to its value intended
by the application (when unmuting) or the framework (0 when
enforcing the restriction).
