Since use of StreamSwitcher causes the worker thread to be changed
during connected device change, its use must be avoided. We intend
to remove StreamSwitcher completely in future.

Move the cleanup of the stream worker thread from '~StreamCommonImpl'
up to concrete stream implementations. This is because when
the worker thread is stopping, it calls 'DriverInterface::shutdown'
method of the stream. At the time when '~StreamCommonImpl' is
running, the concrete stream class has already been destroyed.
The cleanup actually only happens in the case when the client
did not close the stream properly via 'IStreamCommon.close', or
when the stream creation has failed in the middle.

In order to use the time interval for reading from the remote
submix pipe more efficiently, increase the deadline time
to the buffer duration minus a small amount. This should
minimize chances to have discontinuities in the remote submix
input.

The HIDL implementation blocked for the audio buffer duration
when the output side of the remote submix pipe does not have
the sink connected. This behavior was accidentally removed
when fixing b/327220024.
Also, limit the amount of the debug messages displayed when
the sink is shutdown to avoid spamming the syslog.

to prevent glitches in the scenarios that use remote
submix for sending audio externally: Auto and Cast.

device, suggest the configuration of the peer when opening

Refactor SubmixRoute management to move it out from
StreamRemoteSubmix so that ModuleRemoteSubmix could also
use it.

Similar to the primary module implementation, align the time
spent in the transfer operation with the duration of audio.
Change the read operation to ingest as much data as possible
during the audio burst duration.
Ensure that checking the existence of a SubmixRoute and adding
a new one is an atomic operation.
Minor improvements to avoid extra synchronization.
In the configuration, change the limit of max open streams to 10
to match the legacy implementation.

In the configuration, remove "mono" channel masks.
The legacy implementation always used stereo, the framework
handles channel conversion. Otherwise, the input may
be opened with a different channel mask from the output.
In 'prepareToClose', close the output side of the route.
The framework may close the "old" output stream after
it has opened a new one. A call to 'prepareToClose' means
that the framework thread is already shutting down, thus
it is safe to shut down the route.

The implementation had duplicated code in 'transfer', which already
present in 'outWrite'.
Cleaned up delay calculations and logging.
Fixed the VTS to send 'prepareToClose' before attempting to join
the worker. Otherwise, the worker could be stuck on a blocking
operation due to inactivity of the other party and join would never
happen.

Rename DriverInterface::getPosition -> refinePosition. This reflects
the fact that the driver may provide more precise position, however
this is an optional operation.
Rename StreamIn/Out::mContext -> mContextInstance. This is
to emphasize that StreamIn/Out actually own the context and they
hold the real context instance, not just a reference/pointer
to it, like other classes involved in the inheritance chain.

Moving frame counter to the StreamContext class enables
switching stream drivers on the fly while keeping the frame
count monotonically increasing.
StreamWorkerCommonLogic now holds a pointer to StreamContext,
which makes redundant storing copies of the fields of the latter.

Upcoming implementations of the streams of the primary module
will need to change the underlying stream type depending on
the current connected device. The stream context must persist,
thus its life time must be bound to the IStreamIn/Out implementation.
Move the StreamContext instance under ownership of StreamIn/Out.
Add StreamCommonImpl::onClose so that the owner of the context
may know when it is safe to reset it.
Re-arrange the order of the arguments when creating a stream
so that the context always comes first.

This is a method which can be optionally implemented
by a stream in case it can provide more exact position,
for example by taking into account data in intermediate
buffers.
Implemented this method for StreamAlsa and StreamRemoteSubmix.

This method is used to bring out the hardware from standby.
It replaces the ad hoc 'exitStandby' method in StreamUsb.
Streamlined StreamUsb code to avoid locking during transfers.
Updated StreamRemoteSubmix to use 'start'.
Added extra checks to StreamStub to ensure that 'init/shutdown'
and 'standby/start' methods are called as expected. This allows
removing extra checks from non-stub stream implementations.
