audio: new audio devices enum values
Each audio device is identified by a bit in a 32 bit field with
16 bits for output devices and 16 bits for input devices.
The number of output devices is now exhausted.
In order to add new devices a new convention for audio device
identification is defined, allowing 31 different input and output
devices: Bit 31 of the bit field is reserved and when set indicates
an input device.
Also added new output device for wifi display and new input devices
for digital and analog docks, USB and wifi display send.

Device and mode definitions for remote submix
A remote submix is an audio mix of audio streams that
are not going to be played directly through the platform mix,
but rather will be mixed together to be handled in a
different manner. This mix can be obtained by recording
it through the AUDIO_IN_REMOTE_SUBMIX and presenting it
remotely (as opposed to local playback == on the device
itself).
All changes marked "temporary" will be overriden by the
changes to update the audio device definitions for
the 2.0 API.

Declare audio_devices_t as uint32_t & enum consts
Declare audio_devices_t as uint32_t to permit bit operations,
and a separate anonymous enum for the constants. This is similar to
audio_channel_mask_t.
Also remove spurious "typedef" on declaration of anonymous enum for
channel mask constants.

audio policy: add deep audio buffering flag.
Add a value in audio policy flags to indicate an output
stream providing deep audio PCM buffers. Such an output
helps reducing the power consumption at the expense of audio latency.
Stagefright will indicate a preference for such an output when playing music
only (no video) and the audio duration is more than a given threshold.

audio: added definitions for audio HAL device API.
Added definitions for output flags needed by new audio
HAL device API.
These flags where previously defined in audio_policy.h.
Definition in audio_policy.h remains temporarily until
all projects are changed to use new flags.

Fix bug 4319552 Use commonly defined channel mask values in native
The native channel mask values are equal to the Java values, which
differ from other standards simply for legacy reasons. It is
preferrable to use commonly used values, and translate from the
Java constants to the common values when specifying a Java mask.
The new definitions uses the same values and ordering as in
OpenSL ES and other standards.
