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.

## Contributing
libsoundio is programmed in a tiny subset of C++11:
* No STL.
* No `new` or `delete`.
* No `class`. All fields in structs are `public`.
* No constructors or destructors.
* No exceptions or run-time type information.
* No references.
* No linking against libstdc++.
Do not be fooled - this is a *C library*, not a C++ library. We just take
advantage of a select few C++11 compiler features such as templates, and then
link against libc.
