Playing status of audio source is checked using the native handler
not 0.
However, if AudioSystem#startAudioSource fails, the native handler
returned is not 0, but an error code.
In fact AudioPolicyManager sets the PORT to NONE (0) and sets an error
status.
JNI layer transforms the failure status into a native handler returned
to the caller.

Add the possibility for privileged applications to
share part of their audio capture history with another app.
A privileged app with permission CAPTURE_AUDIO_HOTWORD can share part of
its recent capture history on a given AudioRecord with the following
steps:
1) Specify the maximum time in the past that will be available for other
apps by calling setMaxSharedAudioHistoryMillis() on the AudioRecord.Builder
when creating the AudioRecord
2) Start recording and determine where the other app should start
capturing in the past.
3) Call AudioRecord.shareAudioHistory() with the package name of the app the history
will be shared with and the intended start time for this app's capture relative to
this AudioRecord's start time.
4) Communicate the MediaSyncEvent returned by shareAudioHistory() to the other app
5) The other app will use the MediaSyncEvent when creating its AudioRecord by calling
setSharedAudioEvent() on the AudioRecord.Builder.
6) Only after the other app has started capturing can this app stop capturing and
release its AudioRecord.

- Add definitions for the front bottom channels. The name
of the definitions are standardized in ITU-R BS.2051-1.
- Add definition for 13ch mask which consists of surround 5
channels, top 5 channels and bottom 3ch channels. This
channel mask is ideal speaker layout used by Sony 360
Reality Audio. Virtualizer can place individual sounds in
a 360 spherical sound field from these channels on any
headphones.
Ignoring checkstyle warning, "'|' should be on a new line",
to keep existing codestyle.

This CL resolves API reviews on system APIs on MediaRouter2.
1) It checks permission when registering the MediaRoute2Manager
in system server. Therefore, app cannot bypass the permission
checks via reflection.
The system api calls will be no-op without permission.
2) It adds @RequiresPermission annotations to related APIs.
Also, this CL changes the required permission
from MODIFY_AUDIO_ROUTING to MEDIA_CONTENT_CONTROL,
as the media routing can be applied to video, not only to audio.
Note that MediaRouter2#getInstance(Context, String)
does not throw SecurityException anymore.
