50cdc0ac1e Avoid tracing wide-char strings 
Because on Windows, traced strings are written to a char string, which causes
UTF-16 strings to be converted to a narrow (non-UTF-8) encoding, potentially
losing characters.

33ced1a7c2 Try the JACK backend before PulseAudio 
The backend will not spawn a server by default, so PulseAudio will still be
preferred as long as a JACK server isn't already running.

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.

a9cce5de3e Add a lockless ringbuffer 
Largely copied from JACK, it's extended to work with user-specified element
sizes instead of bytes. This is necessary to be able to work with 6- and 7-
channel output modes.

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.
