add mimetype and autoindex option + minor changes

Browse source 
* 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

- `-d PATH`: use `PATH` as the data directory to serve files from. Default is `/var/gemini` - `-d PATH`: use `PATH` as the data directory to serve files from. Default is `/var/gemini`
- `-l LANG`: change the language in the status return code. Default is `en` - `-l LANG`: change the language in the status return code. Default is no language specified.
- `-v`: enable virtualhost support, the hostname in the query will be considered as a directory name. - `-v`: enable virtualhost support, the hostname in the query will be considered as a directory name.
- `-u username`: enable chroot to the data directory and drop privileges to `username`. - `-u username`: enable chroot to the data directory and drop privileges to `username`.
- `-m MIME` : use MIME as default instead of "application/octet-stream".
- `-i` : Enable auto index if no "index.gmi" file is found in a directory.
