[Pkg-clamav-devel] Redo of the initscripts

[Sebastian Andrzej Siewior]

I think I completed the re-do of the init scripts for freshclam, clamd
and milter. I did my last tests yesterday.
The primary motivation was to close #580188. The use a PID file is now
required. start-stop-daemon uses it now to kill the proper daemon. I
also use "pkill -0" to check if the daemon is running.
The change in clamav where I add the extra \n to the pidfile is in
upstream's bugilla as #10907 and should be part of 0.98.2.

The whole thing is in the bigeasy_init branch. Could someone please take
a look at it before it gets into unstable?
