28fa82378b Remove the individual source queue and buffer locks 
They're inherently protected by the mutex for their respective lists. Should
those mutexes be replaced by rwlocks the individual locks should also be
reinstated, but they're unlikely to be unless a lot of contention starts
happening in the read-only case.

e240351d81 Use a semaphore to signal the event handler 
Semaphores allow for semi-persistent signals, compared to a condition variable
which requires a mutex for proper detection. A semaphore can be 'post'ed after
writing some data on one thread, and another thread will be able to recognize
it quickly even if the post occured in between checking for data and waiting.

This more correctly fixes a race condition with events since the mixer
shouldn't be using mutexes, and arbitrary wake-ups just to make sure an event
wasn't missed was quite inefficient.

7256bc92fa Add a thread to marshal events from the mixer 
To avoid having unknown user code running in the mixer thread that could
significantly delay the mixed output, a lockless ringbuffer is used for the
mixer to provide events that a secondary thread will pop off and process.

031cf24880 Use an array lookup for source IDs 
This is now similar to buffers, being stored in groups of 64 in a vector with
the ID providing the array indices.

9613b4bfe2 Use a different method for storing and looking up buffers 
Rather than each buffer being individually allocated with a generated 'thunk'
ID that's used with a uint:ptr map, buffers are allocated in arrays of 64
within a vector. Each group of 64 has an associated 64-bit mask indicating
which are free to use, and the buffer ID is comprised of the two array indices
which directly locate the buffer (no searching, binary or otherwise).

Currently no buffers are actually deallocated after being allocated, though
they are reused. So an app that creates a ton of buffers once, then deletes
them all and uses only a couple from then on, will have a bit of waste, while
an app that's more consistent with the number of used buffers won't be a
problem. This can be improved by removing elements of the containing vector
that contain all-free buffers while there are plenty of other free buffers.

Also, this method can easily be applied to other resources, like sources.
