Switch from --enable-debug config option to BITLBEE_DEBUG env var to be
consistent with bitlbee. This allows us to remove some of the http printouts
as bitlbee will do it itself. Also adding account username to debug
output to distinguish traffic between accs.
This commit introduces own simple libwebsockets implementation removing
libwebsockets dependency. While this can introduce new bugs they should be
easier to hunt down. libwebsockets dependency proved to be very hard to
maintain due to library being in active development and not widely available.
Finally define specific versions in dependencies and switch to autotools
buildsystem. Hopefully this will give us better portability and won't induce
major headaches.
