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().
* follow style(9) for prototypes
* move first most used extension for more effeciciency when looking for mime
* add opts.h to deal with options
* remove lang=en by default
* add option to set default mimetype
* add option to autoindex if no index.gmi found
* redirect if ending "/" is missing
* send appropriate status code if request too long
* edit manpage and README for new options
