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().

Split close into close and release phases.
Release() will release hardware and service resources.
Close() will delete the stream object.
This allows us to defer the deletion and avoid race conditions.
The CLOSING state is used to indicate that a stream has been released.
Added some test cases to test_various.cpp.
A lone call to close() will automatically call release() so we should
have good code coverage for testing.

SHARED streams and endpoints were being created with sharing mode
set to EXCLUSIVE. This was confusing the close() code and caused a hang.
Now we create a modified Request object with the sharing mode set
correctly.

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.
Cleanup close() of MMAP stream.
Add AAudioServiceEndpointShared.cpp.
Extract AAudioServiceEndpointMMAP from AAudioServiceStreamMMAP.
Track MMAP endpoints so we can manage EXCLUSIVE and SHARED access.

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.
