jiabin 574a86fa36 Add AudioTransport to replace AudioProfile in AudioPort.

An AudioTransport contains AudioProfile or hardware descriptor to
describe the audio capabilities for an AudioPort and the encapsulation
type to represent the encapsualtion format that must be used when
sending the audio data with the format associated the AudioTransport to
Android.

The hardware descriptor will be used when the format is not recognized
by the platform.

Currently, the short audio descriptor is added as one of the hardware
descriptors. Short audio descriptor is reported from EDID for HDMI.

Audio HAL

Directory structure of the audio HAL related code.

Run common/all-versions/copyHAL.sh to create a new version of the audio HAL based on an existing one.

Directory Structure

2.0 — version 2.0 of the core HIDL API. Note that .hal files can not be moved into the core directory because that would change its namespace and include path.
- config — the XSD schema for the Audio Policy Manager configuration file.
4.0 — version 4.0 of the core HIDL API.
...
common — common types for audio core and effect HIDL API.
- 2.0 — version 2.0 of the common types HIDL API.
- 4.0 — version 4.0.
- ...
- 7.0 — version 7.0.
  - example — example implementation of the core and effect V7.0 API. It represents a "fake" audio HAL that doesn't actually communicate with hardware.
- all-versions — code common to all version of both core and effect API.
  - default — shared code of the default implementation.
    - service — vendor HAL service for hosting the default implementation.
  - test — utilities used by tests.
  - util — utilities used by both implementation and tests.
core — VTS tests and the default implementation of the core API (not HIDL API, it's in audio/N.M).
- 7.0 — code specific to version V7.0 of the core HIDL API
- all-versions — the code is common between all versions, version-specific parts are enclosed into conditional directives of preprocessor or reside in dedicated files.
  - default — code that wraps the legacy API (from hardware/libhardware).
    - util — utilities for the default implementation.
  - vts VTS tests for the core HIDL API.
effect — same for the effect HIDL API.
- 2.0
  - config — the XSD schema for the Audio Effects configuration file.
- 4.0
- ...
- all-versions
  - default — code that wraps the legacy API (from hardware/libhardware).
    - util — utilities for the default implementation.
  - vts VTS tests for the effect HIDL API.
policy — Configurable Audio Policy schemes.
- 1.0 — note that versions of CAP are not linked to the versions of audio HAL.
  - vts — VTS tests for validating actual configuration files.
  - xml — XSD schemas for CAP configuration files.
