It's probably broken and it's definitely still messy in several ways,
but basic tests work with Chrome.
Several other C websockify cleanups:
- Remove most of the non-thread safe global variable usage (still
a little bit that could be fixed so that threading would be easier).
- Remove wswrapper. It is unmaintained, out of date, and never worked
well anyways (since it really needed a way to do asynchronous queued
work but it was running in another process context making that
hard).
- Use md5 routines from openssl.
- Remove md5.c and md5.h since no longer needed.
Thanks to https://github.com/dew111 for spurring me on to get this
done by writing code. I didn't end up using much his forked code, but
having something there goaded me enough to just get it working.
