- move clc_t into net_clc.h from net_protocol.h
- split packet processing stuff from net.h into net_packet.h
- add a is_server arg to Log_{Incoming,Outgoing}_Packet, so libs/net is
oblivious to if we're running a server or not (except with the arg,
obviously)
- remove the long obsolete (even in original quake) svc_spawnbinary
stuff
- make nq use QF/net_svc.h
- make nq link to libQFnet too
- make qw's cl_parse.c use net_svc_qw_any_t instead of net_svc_any_t
