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

aaudio: indicate client UID and PID to audio flinger
Implement correct indication of client UID and PID to audio flinger
for AAudio MMAP streams in both exclusive mode and shared mode.
- Add start/stop client methods on MMAP streams used only when the MMAP
stream is in AAudio service and carries a mix of shared streams.
- Add "In Service'" indication from "client" side to AAudioServiceStreamMMAP
so that the behavior can be adapted accordingly.
- Modify logic on audio flinger side with regard to mmap tracks and
audio HAL stream activity:
- use same audio session for all clients on a same stream to match
audio policy logic to share same direct output stream for clients on same
session. This is also more consistent with current volume and effect
handling as all MMAP clients sharing the same output stream have the
same volume and use case.
- start/stop the HAL when the stream is started/stopped with the initial client
handle (returned when the stream is opened) but do not create a track.
AAudioService implementation will always send an additional start command before
first client starts and a stop command after last client stops,
in both shared and exclusive mode.
- start/stop a track only if the start/stop stream command is received
with a handle different from the initial handle.
- Allow more than one active client from the same UID on a MMAP input in audio policy.
Bug: 62950008
Test: verify playback and capture in mmap mode
