Add systemd support

[Michael Vetter]

It would be great do have systemd support instead of old SysV Init. I think most major distros changed already.

I'll add it to my TODO list.

The Arch Linux packager already created one which can be used. See service file in: https://aur.archlinux.org/cgit/aur.git/tree/?h=piler

Changes in configure will be needed.

It adds 3 files to systemd dir inside the source tree. You may stop piler-smtp, piler and searchd, then copy them to /lib/systemd/system, then enable them, eg.

systemctl enable piler
systemctl enable piler-smtp
systemctl enable pilersearch

and finally start them or even better reboot to test if they are started properly.
