Subject: [PATCH] Systemd service unit files.

As of August 2014, all Linux distributions include systemd and most of

them enable it by default.

https://en.wikipedia.org/wiki/Systemd#Adoption

There are many systemd HOWTOs, like:

https://wiki.archlinux.org/index.php/systemd

https://coreos.com/docs/launching-containers/launching/getting-started-with-systemd/

https://fedoraproject.org/wiki/Packaging:Systemd

For description of options in the service files, see:

http://www.freedesktop.org/software/systemd/man/systemd.unit.html

http://www.freedesktop.org/software/systemd/man/systemd.service.html

Installation of these files is turned on with --enable-systemd

configure option. They are installed into

PREFIX/lib/systemd/system/ by default. One can also

use --with-systemd-unitdir to specify another directory.

For now the template files reside in src/bin/keactrl/

as I haven't figured out a better place.
