Andrew Kelley ee7c0d3e11 convert source code to pure C 
List<T> is now a really ugly macro.

Added a workaround for jack.h not putting `void` in function
prototypes for functions that take no arguments. I made upstream
pull requests to jack1 and jack2 but I don't have high hopes
about them getting merged.

I removed the lock-free atomic asserts. clang reports
non-lock-free atomics when in fact it does have lock-free
atomics. I inspected the generated code for gcc and clang
for fetch_add, load, and store, on x86_64 and armhf, and
it's all lock free.

Closes #45.

Andrew Kelley c381526205 callbacks supply min and max frame count parameters 
This changes the semantics of the callbacks so that instead of
a single `requested_frame_count` or `available_frame_count`,
the callbacks get a minimum frame count and maximum frame count.

The callback must write at least the minimum or get an underflow.
The minimum will be 0 on ALSA, PulseAudio, and Dummy, and will
equal the maximum on CoreAudio and JACK.

This ensures optimal behavior regardless of buffer size.
