An app (B) that asks for an exclusive stream can steal
an exclusive stream from an earlier app (A).
App B will be given the MMAP resource as a SHARED stream.
The stream for app A will be disconnected and released
by the service.
If app A reopens a stream then it will get a SHARED
stream.
The order of the opening of the streams is controlled by using a
recursive_mutex in AAudioService::openStream().

In aaudio, when adding tracks to mixed stream, it is needed to update
audio attributes to HAL whenever the tracks are added or removed.
Currently, only the audio attributes used to open the stream will be
sent to the HAL. In that case, adding audio attributes of the clients
when starting the stream can help solve the problem. In audio flinger,
the client's audio attributes will be used to create MmapTrack.

There was a potential race between setting the first timestamp
and reading the first timestamp that could cause the timestamp service
thread to exit. This would cause the client to not get any timestamps.
Then the timing model would not advance and the stream would stall.
This could result in read() or write() returning zero,
or a TIMEOUT error.
This was rare except for some devices that had different
timing in the HAL.

The MMAP endpoints were not tracked by the EndpointManager
so it could not broker EXCLUSIVE access. To fix this the MMAP stream
was refactored to use a per-client stream and a per-device endpoint.

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.
