Log:
Work in progress -- this adds unix datagram socket based messaging. This is a
preparation for better cluster messaging, using a shared messaging.tdb
somewhat sucks. It's still around, but only for large messages with no
duplicates allowed. All brlock, share mode and oplock messages can be sent via
the socket.

The USR1 signal is gone, notification works via one of these messages.

The idea is to have a central dispatcher daemon that holds tcp connections to
all other cluster nodes and can then locally send the message via unix domain
sockets.

This central dispatcher will also be a queuing daemon for message sends that
would block. The idea is to sendto() non-blocking directly. If that fails,
send to the dispatcher in blocking mode. As this one does queue everything
correctly guarded by select(), blocking there should not be as bad.

An option is to then implement the duplicates_allowed there, so that only very
large messages need to go through the tdb file.

TODO: write the dispatcher, correctly clean up sockets.
