Now main() is much simpler.
Removed all goto.
Less variables in main.
Simplified status_ to status().
Use a stop() function to log, send messages to stderr if necessary and close vger.
Minor fixes with defaults, mimes
There is still work to do to compare path using stat().
looks for files immediately after the cgidir, and anything after that file
if there are '/'s becomes PATH_INFO.
also adds a function strip_trailing_slash which may be useful in other parts too.
Don't fork+execlp the script. There's no need to do so since on exec
the new process will inherit our file descriptor table (and hence our
stdout), so copying from its stdout to ours is just a waste of time.
This allows to drop the ``proc'' pledge(2) promise and to (slightly)
improve performance.
