Hi all,

Here is a new version of the systemd integration patches.  This time
I've remembered to include the documentation updates.  Speaking of
which, I'm not sure whether I should include the below unit samples as a
guide for people that are wanting to a use socket-activated Emacs
server; I'm not sure whether it is appropriate or where they should go.

emacs.socket
============
[Socket]
ListenStream=/home/foobar/test.socket

[Install]
WantedBy=sockets.target

emacs.service
=============
[Service]
Type=forking
ExecStart=/path/to/emacs --daemon

Feedback & comments welcome!

Changes since v1
================
* Call sd_listen_fds with a paramter of 1 to remove the state that
  systemd sets up.
* Check the socket's validity when passed from systemd.
* Remove lisp functions to simplify the API.
* Change the name of the paramter passed to make_network_process to
  ':usepassedsocket' to keep things more generic.

Changes since v2
================
* Add documentation and NEWS section.
* Rename :usepassedsockets to :use-systemd-socket.

Thanks,
