System-side vendor extension for handling vendor parameters
A mechanism for handling vendor parameters of the Core Audio HAL
is introduced. It is realized by means of a system side interface
'IHalAdapterVendorExtension' which can be implemented by the
vendor in order to provide bidirectional translation between raw
key-value pairs and structured VendorParameter parcelables.
If an instance of 'IHalAdapterVendorExtension' is provided
(for example, via a system ext partition), the audio framework
will use it in order to process parameters that do not map
to methods and fields of AOSP Core Audio HAL interfaces,
and call 'IModule|IStreamCommon.get|setVendorParameters'.
