Get rid of cm.c and cm.h

Since net-server.c now uses libverto, only sendto_kdc.c consumes cm.c.
Move stuff out of cm.c and cm.h into sendto_kdc.c and get rid of them.
Change the sendto_kdc callback (used by chpw.c) to receive the socket
descriptor instead of the entire conn_state structure, and move the
declarations into os-proto.h.  struct remote_address also needs to be
in os-proto.h so that trace.c and t_trace.c can use it.  k5_curtime
isn't needed since k5-platform.h now guarantees the presence of
gettimeofday().
