Only use fast float-to-int workarounds for x87
...
At least SSE and ARM have opcodes that handle float-to-int conversions well
enough. Also, Clang doesn't inline lrintf, incurring function call overhead for
what should be a single opcode.

Improve ASSUME for Clang
...
For some reason, the { if(!x)__builtin_unreachable(); } construct does not
provide the same optimization opportunity for Clang (even though the condition
being false would trigger undefined behavior by reaching unreachable code, it
still performs checks and such for the condition potentially being false).
Using __builtin_assume seems to work better.

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.

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.

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.
