MidiDevice: fix connectPorts for same Process
If connectPorts() was called for a device in the same process then
the connection would die when the ParcelFileDescriptor was closed.

Fix MidiDevice.MidiConnection lifecycle
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.

MidiManager: proxy all requests to open devices through MidiService
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 support for Bluetooth MIDI devices
The Bluetooth MIDI devices are handled in the BluetoothMidiService APK.
Apps wishing to connect to Bluetooth MIDI devices call MidiManager.openBluetoothDevice()
which binds to BluetoothMidiService in a similar way as virtual devices are implemented.

MidiManager: Add MIDI device status notifications
MidiManager clients can be notified of device status changes via a new MidiDeviceStatus object.
MidiDeviceStatus contains the busy status of the device's input ports and number of
connections to the output ports.
MidiDeviceService now has an optional callback for receiving notifications when its ports change as well.

MidiDevice: Add support for making direct connections between ports
The output port of one device can be connected to the input port of another
device using the new MidiDevice.connectPorts() method.
This allows an application to direct the output of one device directly
to the input port of another without having to copy data from one to another.

MidiManager: Virtual MIDI devices are now implemented as Services
To implement a virtual MIDI device, include a subclass of MidiDeviceService in
your application. This service is identified by an intent filter and meta-data
in the application's manifest to allow the MIDI manager to register the virtual device
without actually running the application. Instead, the application's MidiDeviceService
subclass is started on demand when MIDI manager clients want to open the device.
Here is an example of how the MidiDeviceService might be described in the application manifest:
<service android:name="VirtualDeviceService">
<intent-filter>
<action android:name="android.media.midi.MidiDeviceService" />
</intent-filter>
<meta-data android:name="android.media.midi.MidiDeviceService"
android:resource="@xml/device_info" />
</service>
and the device_info.xml meta-data:
<devices>
<device manufacturer="Sample Manufacturer" model="Sample Model" private="false">
<input-port name="my input port" />
<output-port name="my output port" />
</device>
</devices>
(note that the <input-port> and <output-port> names are not currently used, but support for these
will be added in a subsequent change)
Client's of the virtual device will bind directly to the hosting application's MidiDeviceService subclass.
To support this, MidiManager.openDevice() now returns the MidiDevice asynchronously via a callback.
This change also adds a utility class called MidiDispatcher, which is a MidiReceiver
that dispatches all data it receives to a list of other MidiReceivers.
We now use this internally in MidiInputPort and MidiDeviceServer, but developers
may use it for other purposes as well.
