Define a new extra, AudioManager.EXTRA_VOLUME_STREAM_TYPE_ALIAS, to be
sent along with the volume change intent, VOLUME_CHANGED_ACTION.
When sending VOLUME_CHANGED_ACTION, attach the stream type alias.

In order to reduce the number of binder calls, only install an
audio port callback in a client process if either:
- an audio port related API has been called once
- an audio port listenr has been registered.

This allows applications to specify not only channels but also programs
searchable or not enabling finer grained access control.

The app-linking allows channel input sources to provide activity links
from their live channel programming to another activity. This enables
content providers to increase user engagement by offering the viewer
other content or actions.

Update device server's MidiDeviceStatus when a connection is made to one of its output ports.
After connecting an input port to an output port using MidiDevice.connectPorts(),
do not call IMidiDeviceServer.closePort() until MidiDevice.MidiConnection.close() is called.
While I was in there, added missing CloseGuard support to the MidiDevice.MidiConnection class.
This fixes a problem resulting in UsbMidiDevice closing the device's ALSA driver too soon.

Backgroud: As noted in b/20823981, MediaSessionService calls some
audio service methods while holding a lock and the audio service
methods also talk to other system services. And, deadlock happens when
the other system service fires another request to MediaSessionService
while holding its lock.
Example1) --- resolved by the change in MediaSessionRecord.java
T1: MediaSessionService.dispatchAdjustVolumeLocked()
-> MediaSessionRecord.adjustVolume()
-> +++AudioServiceInternal.adjustSuggestedStreamVolumeForUid()+++
-> AudioService.adjustSuggestedStreamVolume()
-> telecom.TelecomManager.isInCall() --- blocked by lock in TelecomManager.
T2: telecom.ConnectionServiceWrapper.handleCreateConnectionComplete()
-> MediaSession.setActive()
-> MediaSessionRecord$SessionStub.setActive()
-> MediaSessionService.updateSession() --- blocked by lock in MediaSessionService.
Example2) --- resolved by the change in IAudioService.aidl
T1: MediaSessionService.dispatchAdjustVolumeLocked()
-> IAudioService.adjustSuggestedStreamVolume()
-> AudioService.adjustSuggestedStreamVolume()
-> telecom.TelecomManager.isInCall() --- blocked by lock in TelecomManager.
T2: telecom.ConnectionServiceWrapper.handleCreateConnectionComplete()
-> MediaSession.setActive()
-> MediaSessionRecord$SessionStub.setActive()
-> MediaSessionService.updateSession() --- blocked by lock in MediaSessionService.
Here, this change prevents the deadlock by making related audio IPC oneway
and calling the internal audio method without holding the lock.

If DEAD_OBJECT is returned from binder calls due to
mediaserver crash, throw new MediaDrmResetException.
This allows the app to detect the condition and handle
it properly.
