This is intended to reduce memory footprint of the default HAL service. The inteface libraries were only used to retrieve interface descriptors and use generated code to register as service. This code was replaced with static code from HIDL transport library. Bug: 148115870 Test: check audio on devices Change-Id: Ie8713d513cfbde64120546ba0db1cf80fd366138
Directory structure of the audio HIDL related code.
Run `common/all-versions/copyHAL.sh` to create a new version of the audio HAL
based on an existing one.
audio
|-- 2.0 <== core 2.0 HIDL API. .hal can not be moved into the core directory
| because that would change its namespace and include path
|-- 4.0 <== Version 4.0 of the core API

|-- common <== code common to audio core and effect API
| |-- 2.0 <== HIDL API of V2
