Change biquad filter to use transposed direct form 2.
...
This change reduces memory usage by removing half the number of delay
registers.
This commit also sets up some infrastructure for future work on a fixed
point implementation. Both the floating and fixed point implementations
will run on a 32-bit pipeline for now.

Bug fixes to the linear resampler.

This changes the the lpfCutoffFrequency config variable from a uint32
to a double. This is required because we simplify the sample rate
fraction which cant result in cases where the cutoff frequency is too
aggressively rounded down due to dividing tiny integers.

WASAPI: Try fixing an automatic stream routing bug.
...
Automatic stream routing should only be used when the ma_device object
is initialized with a device ID of NULL. When it's non-NULL (i.e. an
explicit device) it should not perform automatic stream routing. It
looks like the WASAPI backend is not respecting this requirements and
is enabling automatic stream routing in all cases.
