refactor AudioRecord and AudioFlinger openRecord()
Refactor the mechanism used by audio record tracks to query and
attach to an input mixer/stream in audio flinger. This will:
- reduce the number of binder transactions needed to create a record track
- move sample rate, framecount and flags validations to audio server side
- move audio session allocation to audio server side
- prepare restriction of certain binder transactions to audioserver only
Also:
- renamed openRecord() to createRecord() for consistency with AudioTrack
- make AudioRecord mStatus update consistent when calling default
contructor + set() or constructor with arguments
- make AudioClient, CreateTrackXXX and CreateRecordXXX classes derive
from Parcelable
- restore audio session ID validity check in AudioFlinger::createTrack()
Test: CTS tests: AudioRecordTest, AudioRecordingConfigurationTest, AudioPreProcessingTest
Test: manual test for capture use cases: camcorder, OK Google, VoIP calls
