034935b2e1 Modify how VCALL is handled 
Now instead of specifying the arguments as a third argument to the macro, like
VCALL(object,function,(arg1, arg2));
they are specified separately after the macro, like
VCALL(object,function)(arg1, arg2);

Also, VCALL_NOARGS has been removed in favor of VCALL0, which behaves like
above but expects an empty argument list (a separate macro is needed to work
around preprocessor limitations).

This makes it much more like DirectParams.

94884ed04b Use a separate value for the maximum buffer channels 
Unlike the device, input buffers are accessed based on channel numbers
instead of enums. This means the maximum number of channels they hold
depends on the number of channels any one format can have, rather than
the total number of recognized channels. Currently, this is 8 for 7.1.

52096234e1 Limit the source step to 10 
This means the combination of the buffer frequency, source pitch, and
doppler shift can't exceed 10x the device playback frequency.

This is needed to keep the mixer from starving with a really high
increment, causing small DstBufferSize values that require a lot of
iterations.

48aa1e10d6 Use the high-shelf filter in place of low-pass 
They effectively both work to lower (or raise) high frequencies. However, the
high-shelf performs better when gain=1.

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.
