Send audio patch in recording callback
Remove direct access to patch handle in AudioInputDescriptor, replace with
set / get functions.
Add interface for AudioSession to query configuration from enclosing
input descriptor.
When input descriptor's patch handle changes during a recording, propagate
the change through the recording notification callback.
