Log:
This is an incomplete (but non-intrusive, ie it should not break anything
existing) prototype of a new winbind architecture. My main problem with
winbind is that a single irresponsive DC or a simple timeout connecting to a
new DC stalls the complete daemon. A simple "getent group" on a large domain
with trusts has a similar effect.

I'm checking this into head, hoping for feedback on the architecture before I
start to expand it (ADS connects, group stuff) and rewrite winbind_nss_linux.c
& friends.

The new winbind forks off sub-daemons that listen on /tmp/.winbindd/lsa and
/tmp/.winbindd/samr-<sid>. For each socket there's a separate daemon that is
only responsible for his particular pipe. The interface on the sockets is a
simple text-based one:

vlendec at delphin:~> tcpcat -e /dev/null -u /tmp/.winbindd/lsa
connected to unix:/tmp/.winbindd/lsa.
