don't crash on wrong vhost or missing SNI
the new logging code was crashing if the client didn't support SNI or if required an unknown vhost: this because we short-circuit in handle_handshake to an error, so c->iri isn't populated yet (we don't even read the request). fixes #1
improve logs
now we log the full IRI requested (before was only the path) and the response line (even for CGI).
improve mime handling
we still have an hardcoded list, but this implements the API needed to modify the mappings.
removing err/warn functions with our fatal
err/warn is not available on some systems (unfortunately!) and in any case don't play well with our daemon mode (that closes std{in,out,err}). Use our fatal that is daemon-aware.
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.
re-enable daemon mode
with the split into two process, the call to daemon was lost
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.
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
