improve logs
now we log the full IRI requested (before was only the path) and the response line (even for CGI).
drop useless field
was probably added to distinguish between AF_INET and AF_INET6, to use different functions for logging. But it wasn't really used, and now we use getnameinfo anyway.
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.
removing O_CLOEXEC
we don't fork anymore in that process, so the flag is extra.
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.
