When there are no device ports supporting MMAP, Module::getMmapPolicyInfos have to return 'Policy::NEVER' so that the AAudio code does not attempt to use the AAudio service. This aligns with the use of sysprops by the HIDL implementation. Update AudioCoreModule#GetMmapPolicyInfos test to use the same logic for determining MMAP support as the framework uses. This makes CtsNativeMediaAAudioTest cases passing with the AIDL HAL on Cuttlefish.

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.halfiles can not be moved into thecoredirectory 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 inaudio/N.M).7.0— code specific to version V7.0 of the core HIDL APIall-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 (fromhardware/libhardware).util— utilities for the default implementation.
vtsVTS tests for the core HIDL API.
effect— same for the effect HIDL API.2.0config— the XSD schema for the Audio Effects configuration file.
