Support receiving a parameter that sets the remote audio submix
module in a state where the audio pipe will unblock any current
write operation and not block anymore.

The way buffers are passed to JPEG encoders makes it difficult to
account for a header offset. This explains moving the header to
the end, and clarifies the required header packing.

The hotplug callback is non-reentrant. The display config functions
return an error if called for a disconnected display type.

To simplify passing compressed JPEG data between the HAL and the
camera service, add a transport header for use with JPEG streams.

The reference count on the strong pointers to the audio sink and
source should be done on the object retrieved from the device
structure, not by accessing the corresponding fields, as they
can be cleared while reading or writing audio data.

Change how the remote audio submix is handling piping audio
through the pipe:
- use a MonoPipe as audio sink for blocking writes,
- use a MonoPipeReader as audio source for non blocking reads,
and keep track of when recording started to align the
time at which the in_read() call should return with the
projected time of the recording duration.

Until all HAL implementations move to the new gralloc format selection
scheme, define FORMAT_ZSL for indicating ZSL streams.

Neither write nor read are blocking, but write simulates
timing by checking the clock between two writes and
computing how long the next sleep should last.

Changed audio device API version to 2.0 because of
new enums for audio input and output devices.
Removed implementations of get_supported_devices() in
stub and usb audio modules.

New definitions of audio devices for remote submix: one representing
a sink for writing the audio buffers that won't be played directly
locally, another representing the audio source that can be read from
to obtain the audio mix.
New audio hardware module encapsulating the submix loop functionality.
Create a Pipe to serve as non-blocking audio ring buffer between
the output device (the sink) and the input device (the source).
