moving "default type" from global options to server options

add "lang" server option

move mimes into the struct config

add "mime" and "default type" option for the configuration

improve mime handling we still have an hardcoded list, but this implements the API needed to modify the mappings.

reorganize: move bunch of functions to server.c cgi.c wasn't really needed; it better to group all the server related functions together, cgi or not. Now gmid.c contains only startup and utility code.

split into two processes: listener and executor this way, we can sandbox the listener with seccomp (todo) or capsicum (already done) and still have CGI scripts. When we want to exec, we tell the executor what to do, the executor executes the scripts and send the fd backt to the listener.

move cgi stuff to its own file

add protocols to the config

style

sandbox also on FreeBSD with capsicum

conf & vhosts * gmid.c (main): changed behaviour: daemon off by default (main): changed -c in -C (cert option) (main): changed -k in -K (key option, for consistency with -C) (main): added -c to load a configuration (main): certs, key and doc (-C -K and -d) doesn't have a default value anymore (handle_handshake): add vhosts support

track handshakes This alter the current state machine by adding S_HANDSHAKE as the initial state. There, we ensure we did the handshake and we check SNI. ATM we simply continue in S_OPEN, but later we can add virtual host checks there, and skip to S_INITIALIZING with an error state if the client is accessing a wrong host.

avoid __dead and return at the end of main

fix build on non-OpenBSD systems not every system has a __dead attribute for functions. This fixes the build on FreeBSD.
