struct audio_config definition moved from hardware/audio.h to
system/audio.h for use inside the framework and not only at the HAL.
Added frame_count field to struct audio_config.

Flag AUDIO_FLAG_BEACON characterizes streams where the system
ensures that the playback of the sound will be compatible
with its use as a broadcast for surrounding people
and/or devices. Ensures audibility with no or minimal
post-processing applied.

New Usage Type: AUDIO_POLICY_FORCE_FOR_HDMI_SYSTEM_AUDIO
New Config Type: AUDIO_POLICY_FORCE_HDMI_SYSTEM_AUDIO_ENFORCED
When HDMI-CEC system audio mode is enabled, AudioService will
call
setForceUse(AUDIO_POLICY_FORCE_FOR_HDMI_SYSTEM_AUDIO,
AUDIO_POLICY_FORCE_HDMI_SYSTEM_AUDIO_ENFORCED);
in order to notify enabled system audio mode, so that
audio policy manager chooses proper output.
When it turns into off, AudioService will call
setForceUse(AUDIO_POLICY_FORCE_FOR_HDMI_SYSTEM_AUDIO,
AUDIO_POLICY_FORCE_NONE);
Along with it, add new audio output devic type,
AUDIO_DEVICE_OUT_AUX_LINE, in order to distinguish
line out for headphone and aux output of av device.

Added definitons and structures for new audio routing features
in the framework and audio HAL.
The structures describe the objects needed to perform audio
routing and audio gain control: different variants of audio ports
and their corresponding configurations as well as gain controllers.

to AUDIO_CHANNEL_OUT_QUAD_BACK and AUDIO_CHANNEL_OUT_5POINT1_BACK
respectively, for consistency with terminology used in downmix effect
For the time being, preserve the old names to avoid changing existing code.

Adding opus to the list of audio formats enum.
This CL is part of adding Opus decoding support to android.

- This is a complimentary change to the one adding this new source to
MediaRecorder.java
Bug: 10640877.
Change-Id: Ie213e82b5a60dad2a277cef367c2f5e4df70df06
Also:
- Use correct type name audio_channel_mask_t
- Use the parameter name 'channelMask' instead of the more ambiguous 'channels'
Change-Id: I22bc1821a1bded0e69fe7d99e7b981ff60d77cee
- Defines audio output flags for offloaded playback of compressed
streams, and non-blocking HAL write()/drain()
- Adds audio_offload_info_t to pass additional information about a
compressed stream when offloading

Added a value to audio_channel_mask_t enum for front + back mic
combination to allow parsing of audio_policy.conf file by audio
policy manager.

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.

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 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.

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.
Change-Id: I0e6a9f5746a22d2bfea2b21dd182489a34a4b528
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.
