lib: Add unix_msg
This is a messaging layer based on unix domain datagram sockets.
Sending to an idle socket is just one single nonblocking sendmsg call. If the
recv queue is full, we start a background thread to do a blocking call. The
source4 based imessaging uses a polling fallback. In a situation where
thousands of senders beat one single blocked socket, this will generate load on
the system due to the constant polling. This does not happen with a threaded
blocking send call.
The threaded approach has another advantage: We save become_root() calls on the
retries. The access checks are done when the blocking socket is connected, the
threaded blocking send call does not check permissions anymore.
