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.

70fbc2b1ff Add a function to get a list of data files 
The method takes a marked-up filename (e.g. may include %r for a sample rate,
%% for %, etc), and returns a vector of strings of found filenames that match.
It will search the CWD, the local, and global data directories, in that order.

46bbf95bae Disable mmdevapi capture and update changelog 
Unfortunately mmdevapi does not do channel remixing or resampling, even for
capture, so the device can only be opened in the mode it's configured for.
For now, fallback to dsound or winmm to get the conversion until we can do it
ourselves.

87f3babe2c Append "on OpenAL Soft" to mmdevapi, dsound, and winmm device names 
Would be nicer to have a more backend-agnostic method of doing this, Perhaps
even also only when the router is being used.

ce487d1e43 Use the correct device name for PulseAudio too 
Like mmdevapi. duplicate device names will have a '#2' or such appended, so the
device's reported name may be incorrect.

c24f4f230f Use the lockless ringbuffer for mmdevapi capture 
The backend's capture funcs are already called while under a lock, so multiple
threads shouldn't be able to read from it at once.

e5964d6dc4 Double check the mmdevapi capture format 
This isn't a real solution, but it should get IAudioClient_IsFormatSupported to
stop failing.

e53861bfb9 Always use the JACK server buffer size as the update size 
The buffer-size config option now only specifies an additional mix ahead to
keep ready for audio requests, rather than a pretend period size.

93b69583d3 Try the device-specified channel configuration first 
This does basically no checking that the channel config is correct, but should
be good enough for when non-stereo modes are requested.

e84b3f4707 At least measure the ringbuffer size for JACK's latency 
We should also add the port latency, but there's currently no way to ensure
it's synchronized with the ringbuffer (the ringbuffer will update before the
port latency gets updated).

7e6d0d6b4f Fill out the JACK playback backend 
A few notes about it:

The OpenAL device's requested buffer metrics are ignored, and instead the
device will keep one JACK-sized buffer's worth of audio prepared for JACK's
next process request.

Output is restricted to 32-bit float stereo. Part of this is because JACK
requires a buffer size that's a power of 2 (measured in samples), and the
ringbuffer requires a buffer size that's a power of 2 (measured in bytes). A
channel count of 6 (5.1) or 7 (6.1) will not work without causing a sample to
split over the edge of the ringbuffer. Additioanlly, JACK doesn't provide
information about what channel configuration a device or set of ports has, so
there's no way to know what ports 3 and up map to (even the first two ports are
unknown, but assuming stereo seems to work well enough).

There is no device latency measurement (for AL_SOFT_source_latency) due to the
non-atomicity between the ringbuffer's read size and port latency. A method is
needed to ensure the ringbuffer's read size and port latency can both be
measured between the end of a JACK update cycle (when the port latency has been
updated with the newly-retrieved audio) and the following ringbuffer read
update.
