tmux/server-job.c
Tiago Cunha cc9ef11985 Sync OpenBSD patchset 438:
Split the server code handling clients, jobs and windows off into separate
files from server.c (merging server-msg.c into the client file) and rather than
iterating over each set after poll(), allow a callback to be specified when the
fd is added and just walk once over the returned pollfds calling each callback
where needed.

More to come, getting this in so it is tested.
