Move ExtendedAudioBufferProvider.h to libaudioclient. This is
a more appropriate location because EABP extends AudioBufferProvider.
Move SingleStateQueue.h to libnbaio_mono. This is a more appropriate
location because SSQ is a non-blocking queue.
This allows to remove the dependency of libnbaio on libmedia
which is a good thing because libnbaio provides more low-level
abstractions than libmedia.
Also, replace a dependency of libnbaio on libbinder with
a dependency on libaudiohal header library.

Add an api to IMediaMetadataRetriever to decode image rect.
It will reuse the same full frame IMemory, and decode only
the requested rect. For now, StagefrightMetadataRetriever
will only allow decoding of rect that's a full row of tiles,
and the requested must be issued sequentially (i.e. no
arbitrary rects). When the extract side is fixed to allow
seeking by tiles, it can be extended to allow arbitrary
rects.
This allows HeifDecoderImpl (on client side) to start
processing the getScanlines in parallel with the decoding.
Test: CTS MediaMetadataRetrieverTest;
Manual testing of HEIF decoding of files with or without tiles;
Manual testing of HEIF thumbnails generation in Downloads app.

When extracting bitmaps, MediaMetadataRetriever does a copy from
StagefrightMetadataRetriever's VideoFrame to IMemory. We could
just allocate IMemory directly and return that to the client.

Prior to this CL, if an AudioTrack client wrote audio data after
AudioTrack stop(), but before the track was drained by the server,
the newly written client data would be consumed in the drain.
We now limit the server read to the client write position on stop.
This interlocking is essential for rapid asynchronous AudioTrack
command processing.

Normally the flush is processed on ObtainBuffer.
But that is not called when the track is paused.
So it was not possible to flush and re-prime a
track that was paused.
Now we flush synchronously for inactive tracks,
and flush from prepareTracks_l for active tracks.

The server was waiting for a full buffer.
But the buffer was only getting partly filled.
So the stream was not starting.
The fix involves having the server look at the adjustable threshold.

When audio flinger mixer removes an AudioTrack from the
active list in case of underrun, it is possible that the
client has written a full buffer just after the underrun detection and
is blocked waiting for more space to write. In this case, the client
will never detect the DISABLED flag and the track never be restarted.
Also implement missing DISABLE flag detection in server side audio tracks
(OutputTrack and PatchTrack).

StaticAudioTrackServerProxy::framesReady() previously returned
only the contiguous frames, update to return the total
available frames. This resolves short-count looping in
SoundPool for FastTracks.
Also (1) Removes the racy condition of reading two variables
and (2) Fixes buffer->mNonContig to return the correct value
and (3) Restores behavior that loop count of 1 goes back to
loopStart once during playback.

Add support for audio device connections between different audio
hw modules.
The patch is performed by creating a bridge between the playback
thread connected to the sink device and the record thread connected
to the source device using a pair of specialized PlaybackTrack and
RecordTrack.
- Added PatchTrack and PatchRecord classes.
- Added TrackBase type to indicate more clearly the track behavior.
- A TrackBase can allocate the buffer or reuse an existing one.
- Factored some code in openOutput() and openInput() for internal use
by PatchPanel.

This will allow (eventually) a greater dynamic range for gains.
However there are still a few remaining places in effects and mixer
that will also need to be changed in order to get the full benefit.
Also fixes a minor bug: was not checking for NaN in AudioTrack C++.
