Remote playback information updates will be posted from the
application thread, and sent to AudioService. Because they
require locking the stack containing the remote playback
information, the update should happen on AudioService's handler
thread to avoid lock contention.

Extend MediaRouter.UserRouteInfo to enable setting playback
information, which includes volume. When the user route instance
has a RemoteControlClient, forward any playback information to it.
Enable specifying a callback to be notified of volume events
on the route.
Extend MediaRouter.RouteInfo to enable retrieving playback
information.
Update RemoteControlClient javadoc to reflect which parts of the
API are not intended to be made public.

Remove bluetooth permission check from internal AudioService method
setBluetoothA2dpOn
Manage BT A2DP state in MediaRouter. A2DP is only enabled or disabled
when either the system built-in audio route or the A2DP audio route is
selected; when selecting any other route the current state is left
alone.

Extend RemoteControlClient class to enable an applicaton to
specify more information about how it's playing media, now covering
usecases where media playback happens "remotely". This playback
information can be used to set the volume and maximum volume
used remotely.
Declare a new intent and associated extras in Intent,
ACTION_VOLUME_UPDATE, so an application can be notified that
the volume it handles should be updated. It can then use
the new RemoteControlClient.setPlaybackInformation() method
to notify AudioService what the volume is.
Extend AudioService to maintain playback information associated
with the RemoteControlClient information in the stack of
media button event receivers (mRCStack). The information
about the active remote is cached so the stack doesn't have
to be iterated over in order to retrieve remote playback info.
Events to "adjust" the remote volume based on hardware key
presses cause the client application to be notified of
volume updates, and the volume panel to display the volume
set by the app.
Revise which stream type is controlled when none is specified
according to latest guidelines for remote playback.
Update VolumePanel class to support a new pseudo stream type,
AudioService.STREAM_REMOTE_MUSIC, that corresponds to the
remote playback volume, and uses the new "media route" icon.
Enable it to receive asynchronously new volume values for
the remote that will be displayed if the UI is still up,
and ignored otherwise.
Now supports hiding/showing sliders dynamically so remote
volume only appears when AudioService has a remote control
client handling remote volume.
Define new java symbols for the two media route icons.
Modify lockscreen behavior: don't automatically control music
volume when music is active, consider also remote playback.
Still to do:
- playback information set by RemoteControlClient should post
a message for AudioService to update playback information
instead of updating it synchronously

MediaRouter dialogs now intercept the volume keys for altering the
current volume. The status icon indicates if the slider/buttons are
currently controlling the local device volume or a remote device's
volume.
Group volume for user routes is handled by using the
RemoteControlClient supplied by the first route in the group.

Improve the API around ActionProvider visibility overriding. Allow the
application to notify whatever is hosting the ActionProvider that
visibility has changed in a way that is friendly to alternate support
library-style reimplementations of MenuItem.
Allow MediaRouter.Callback implementations to add or remove themselves
or other Callbacks during dispatch of callback events.
Make MediaRouteActionProvider track the visibility of corresponding
menu items more accurately.
Change-Id: Ic7ddb6a87c3637904750d2661e4a9fa323b09ea0
* Add ActionProvider#overridesItemVisibility and isVisible.
These methods allow an ActionProvider to override the
visibility of a MenuItem that it is bound to. If a MenuItem
has been explicitly hidden by the application, it will not
be visible.
* Change MediaRouteActionProvider to not require a MediaRouter
callback, to avoid extra lifecycle management headaches.

The AudioService now has an API to call to get the currently
connected devices, and later reports of changes in connection
state. The information includes the name of the bluetooth
device if one is connected for display to the user, and states
for all of the pluggable devices. No longer requires a Bluetooth
permission to keep the routes updated.

Come back to old versions of setBluetoothA2dpOn() and isBluetoothA2dpOn().
MediaRouter will call methods on IAudioService directly.
Change-Id: I18f0a3106bad78715ed11a6b7b4ec1d656cdae41
* Accept a Context when fetching the names of routes and
categories. This lets string resources resolve at time of access
with the correct configuration. The older versions remain available
that will use the static resources from the application. (There are
enough cases where applications will populate this from external
data that requiring it each time even when it was not initialized
from a resource doesn't seem reasonable.)
* Remove the ability for apps to programmatically select non-user
routes.
* Make MediaRouter.Callback an abstract class instead of an interface.
This will make further extensions easier to keep compatible in the
future.

Add the dialog behavior for MediaRouteActionProvider/MediaRouteButton.
Still TODO:
* Switch audio icon based on source; speaker/bt/user
* Rig up volume slider
* Rig up item icons
* Rig up group button for groupable categories
* Make grouping work
