this completes the splitup of server.c.

the splitup was done with an axe, not a scalpel, so there are some
rough edges. I mostly wanted to get the general form right with fine
tuning of what goes where to come later. Still, this is better than
what we had before where server.c was a general repository for
anything that didn't fit elsewhere.
