For small buffers, the driver can perform draining
synhronously, returning control to the HAL only after
the buffer is empty. This makes going through
the 'DRAINING' state artificial. Thus, we allow going
to the 'IDLE' state directly.
In order to make sure that VTS handles both transitions:
to 'DRAINING' and to 'IDLE', correctly, add an "AOSP as
vendor" parameter "aosp.forceSynchronousDrain" to induce
this behavior in the default implementation.

The binder passed to AIBinder_setMinSchedulerPolicy must also be
returned to the client, otherwise setting the policy for it does
not make any sense. However, server side interface instance
classes only hold a weak binder reference. It's the caller of the
'asBinder' method who must retain a strong reference. This
reference must be retained past exiting from the method which
returns the instance to the client.
To solve this issue, add storing of binders along with server
object references. These binders get released after the client
calls a 'close'/'destroy'-type method to release instance
resources.

Previously StreamDescriptor::Command used to be a parcelable
holding a command code (enum) + a command argument which was
used for one command only. This got replaced with an equivalent
union, where each command w/o arguments is represented by a
'Void' variant, and the command with an argument with a variant
of a corresponding type.
This has the following benefits:
- the union guarantees that the argument is only set for
commands that actually use it, thus all related comments
and validations can be removed;
- the command dispatch can be turned into an exhaustive
switch.
To be able to use an exhaustive switch, the 'exit' command
has been exposed at the interface, but marked as 'hal_reserved'.
