tonihei 481205a88f Use Futures for MediaSession command queue instead of Runnables
Some commands may be asynchronous and subsequent commands need to
wait for them to complete before running. This change updates the
queue to use (and listen to) Futures instead of calling Runnables
directly. The commands are currently still added as Runanbles
though, so this change is a no-op.

Also moves the permission check in MediaSessionImpl to before
queueing the command because the permission should be check at
the time of calling the method.

When executing the comamnds in the queue, we need to be careful
to avoid recursion in the same thread (which happens when both
the Future is immediate and running on the correct thread already).
To avoid recursion, we detect this case and loop the commands
instead.

Session module

This module provides media session functionality through which media information and controls can be exposed to the Android platform, as well as to other processes and applications.

Getting the module

The easiest way to get the module is to add it as a gradle dependency:

implementation 'androidx.media3:media3-session:1.X.X'

where 1.X.X is the version, which must match the version of the other media modules being used.

Alternatively, you can clone this GitHub project and depend on the module locally. Instructions for doing this can be found in the top level README.
