RemoteControlClient has an interface for the framework to query
the playback position. This mechanism is used to detect
when the estimated position drifts from the real position by
having the framework regularly poll (every 15s when playing at
1x) this interface and compare against the estimation.
But this mechanism:
- should only be used when IRemoteControlDisplay implementation
care about position display
- should not be used by default because the implementation of
the position query interface might involve network traffic
in some remote media player implementation for instance.
This CL implements an opt-in mechanism to be used by
implementators of IRemoteControlDisplay, to request the
anti-drift mechanism to be turned on.

API change in f0d4777473f25847d67fc17fc082fada08cf678d didn't update a

Periodically verify that the reported playback position hasn't
drifted from the estimated playback position.
If a drift is noticed, re-synchronize registered
IRemoteControlDisplay implementations.
bug 8120740
Note that this implementation updates the playback position
of all IRemoteControlDisplay implementations,
and always causes the OnGetPlaybackPositionListener to be
called. This might be undesirable in some circumstances
and will be addressed in a subsequent CL.

After commit 25fc29b3, AudioManager.startBluetoothSco()
does not use virtual voice call mode anymore when starting the
SCO audio connection to the headset.
To help backward compatibility, this change makes that virtual voice call
is used if the request comes from an application targeting a SDK version
before JB MR2. For applications targeted to JB MR2 and above a raw SCO
audio connection is established.

Missing 'break' when handling MSG_SEEK_TO message.

The new media button receiver with only a pending intent (no
component name) could be left hanging if the process that
registered it went away. These semantically need to be tied
to the calling process's lifetime; we now clean them up when
the calling process goes away.
Also added some additional cleanup of media button receivers
when packages change (updated, cleared).
And on top of that, a new "media" command for doing media
things. Currently lets you send media keys and monitor
remote display data.
Oh and finally added a new BaseCommand base class for
implementing these command line utilities.

Do not use startScoUsingVirtualVoiceCall() BluetoothHeadset
API to connect SCO audio. This will cause headsets to act as if an incoming
call was received which is not what we want for voice commands.

RemoteControlClient defines two listener interfaces for playback
position, one to let the framework query the current playback
position, the other to request playback to seek to a given
position.
Updated IRemoteControlDisplay interface to support passing info
about whether the user of RemoteControlClient can provide a
playback position, and receive a new one.
Updated implementations of IRemoteControlDisplay to new
interface.

Removed storage of last audible stream volume index.
This information is redundant because we already have
two pieces of information (current volume and mute state)
allowing to completely define which volume should actually
be applied by the framework or indicated to apps.
The last audible index management had anyway been broken by
successive changes making that the value stored could be 0
in some cases causing problems like issue 8109149 when
restoring the volume settings from the DB.

A public API was added to AudioManager to register a media button
event receiver whithout having to supply a ComponentName.
This CL updates the comments that specified that the now optional
ComponentName parameter can be null, and never persist the button
event receiver is there is no ComponentName to persist.
Also unregistering the media button receiver makes no use of
the ComponentName anymore.
