c1f87414c5 Mix to multichannel for effects 
This mixes to a 4-channel first-order ambisonics buffer. With ACN ordering and
N3D scaling, this makes it easy to remain compatible with effects that only
care about mono input since channel 0 is an unattenuated mono signal.

8f26ad4ba2 Avoid using scandir/alphasort 
They require POSIX 2008, which is a bit too "new" for my current liking. We can
do well enough with opendir/readdir/closedir and qsort.

21c84bcd96 Replace deprecated Carbon API calls with modern AudioComponent APIs in the CoreAudio backend. 
This prevents a deprecation notice from being output to stdout when alcOpenDevice is called in Mac OS X 10.11.

The new API calls require Mac OS X 10.6 or newer.

5d039309b3 Use doubles for the constructed listener matrix 
This helps the stability of transforms to local space for sources that are at
or near the listener. With a single-precision matrix, even FLT_EPSILON might
not be enough to detect matching positions.

b9e192b78a Implement a band-limited sinc resampler 
This is essentially a 12-point sinc resampler, unless it's resampling to a rate
higher than the output, at which point it will vary between 12 and 24 points
and do anti-aliasing to avoid/reduce frequencies going over nyquist.

Code provided by Christopher Fitzgerald.

dce3d0c7bf Change the Kaiser rippling limit to -60dB 
This improves the transition cutoff, shortening its width and reducing the
amount of error.
