UsbMidiDevice: Clean up terminology and fix comments
When working with physical MIDI devices, an *input* stream is used
for reading from *output* port of the device, and vice versa. Thus,
using "input" and "output" without specifying whether it's a stream
or a port is confusing.
Clarify names of counter variables, and fix a couple of comments
that were incorrect due to this confusion. No functional changes.

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.

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.

MIDI Manager: Remove message packetization from MIDI transport
Instead of attempting to package exactly one MIDI message in each call to
MidiReceiver.onPost(), we now pass messages as a raw stream of bytes.
This means we may now receive multiple MIDI messages in MidiReceiver.onPost().
We make this change to avoid the complexity of taking the single message approach
with SysEx and realtime messages. This shifts some of the burden of parsing
MIDI messages to the client application. But the parsing is best handled in the
application anyway, rather than having the framework impose its own policy
on how the messages are parsed.

MidiManager updates:
MIDI ports are now implemented as file descriptors directly between the sender
and receiver, so the MidiService is no longer in the message path.
To facilitate the above, each port has its own file descriptor, rather than multiplexing
all ports on a device through a single socket.
Added a new class MidiDeviceServer, which is used by implementors of MIDI devices.
This replaces the MidiVirtualDevice class (which only was included in changes that were reviewed but never submitted).
The USB MIDI implementation has moved from the MIDI service to the USB service.
The USB MIDI implementation uses MidiDeviceServer as its interface, so we now have a common
interface for all MIDI device implementations.
