Minor text cleanups

• Split more code into a function
• Move all functions to top
• Wait for PHP to restart
• Really use correct rules.debug files

• Use system
• Use correct filename

Show rule differences (rules.debug) after a sync. Handy if you have
changed filter.inc.

Minor formatting and text refinements

Correctly set nobackup flag

• Exclude /var/dhcpd/dev/ from backups
• Split out long excludes into shorter assignments

Add missing exit

Exit before upgrade, etc on failure

Test php after cvssync. If you go backwards in time your PHP will puke.
If php pukes and a previous backup exists, just restore it.
