f7c176e8ca Use a message thread to handle MMDevAPI backend methods 
Because MMDevAPI uses COM, CoInitialize must be called on the thread(s) where
the device calls are made. OpenAL has no such requirement, thus no guarantee
that COM will be (or remain) initialized on the calling thread(s).

3e2bc847d8 Avoid closing devices and deinitializing backends on process exit 
They are still closed and deinitialized when the DLL is simply being detached
(via FreeLibrary), however.

c8326ab328 Remove the unnecessary wave header event 
It's only ever set before sending the quit message, which will set the thread
event. It's also only waited on just before the thread event is used to signal
the end of the thread.

1b0a55f44c Use real-time priority by default on Windows 
It's actually "time-critical", but it seems normal priority doesn't cope as
well when the system is under moderate load.

3e4659076a Use an event to signal the mmdevapi backend to mix 
Also, use a multiple of the default period size for the update size, since the
event apparently triggers on period boundaries.

9723c553b6 Scale reverb output based on the number of channels 
A scale of sqrt(2/numchannels) is used so the perceived volume matches as if it
was stereo output, which seems to match other implementations.

163cc62a00 Add a couple new functions to handle deferred updates 
Currently no-ops, they will be used in place of alcSuspendContext and
alcProcessContext for batching updates since the mentioned functions have no
coherent functionality between system implementations.
