a7ad6080f0 Modulator fixes 
Modulator functions return 0..1 instead of -1..+1
Apply high-pass filter before modulation
Increase fractional precision to 24 bits from 16

563f16dc2a Fix overflow issues when converting float to int 
32-bit floats can only reach between -16777215...+16777215 (25 bits) before it
starts losing whole-number accuracy. Some compiler optimizations may break
trying to multiply a float by 2147483647.0 when the result is given right to a
float parameter, causing it instead to multiply by the nearest representable
float value, 2147483648.0.

bf54de4984 Use less math to clamp floats to -1...+1 
The previous code could have issues as precision lowers. This should hopefully
work better while only using one if check instead of two.

1fb9311d82 Lock the device before calling aluHandleDisconnect 
PulseAudio causes an assert if being relocked inside a callback on the worker
thread, where aluHandleDisconnect is called. We can assume it's already locked
there, so just make sure the device is locked before being calling it.

209d09ae13 Avoid locking PulseAudio's mainloop when starting and stopping capture 
The mainloop is already locked by the caller, and double-locking interferes
with the subsequent wait.

92dde81296 Add rudimentary latency tracking for mmdevapi 
This won't be as granular as it could be, since it only updates when the wakeup
event trips (which may or may not happen more often than OpenAL's mix updates).
A more correct method would be to query GetCurrentPadding directly, but that
would require sending a message to the processing thread and waiting for a
reply, since we can't guarantee COM on the calling thread.
