This prevents a (highly improbable) race condition when exiting, and uses
pcm_set_frequency() instead of mixer_set_frequency(), since that seems like
the Right Thing to Do (TM).

Rather than holding intermediate results as fixed-point, this converts them
directly to normal integers (in the range of the PCM sample) while mixing,
instead of waiting till the end to perform a separate shifting step. Also,
this precalculates some constants in the reverb code.

This allows CPU load to drop below 100%, which is good for anything
that scales frequency and voltage based on CPU load. Also conserves
some energy by letting the core go idle if there aren't any available
buffers.

Using the coprocessor was a good idea in theory, but didn't actually work.
This moves all SDL threads to the main core, which isn't ideal, but at
least works. Additionally, this also adds some good-practice stuff such as
setting the default sample rate on exit.
