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.

Fix performance regression in SoundPool by not checking SoundPool
can play audio everytime it's about to play.
Instead check for permission in constructor and register a listener
for changes on OP_PLAY_AUDIO.

For certain RtoL languages, digit used as a part of input id
(like HW0) is also localized, hence language change results in
the duplicated inputs for an identical hardware. This CL
changes the way the id is built to language-neutral fashion,
and keeps the digit used in the id in Arabic.

Previously when a MidiManager client opened a virtual or Bluetooth device,
the client bound directly to the virtual device's MidiDeviceService
or BluetoothMidiDevice's IMidiDeviceServer for the given BluetoothDevice.
Only USB devices were opened in MidiService.
Now opening any type of MIDI device is done via IMidiManager.openDevice() or
IMidiManager.openBluetoothDevice(). MidiService tracks all connnections between
clients and devices.
Services that implement virtual devices must now require android.permission.BIND_MIDI_DEVICE_SERVICE
so only MidiService can bind to these services.

Add virtual MIDI devices to bullet list.
