pfsync locking changes - please test

[Bjoern A. Zeeb]

Hi,

here's a combined patch of all but the one change I already posted earlier
today.

http://people.freebsd.org/~bz/20111019-03-pf-pfsync-locking.diff

If you want to help testing on stable/9 apply both.  Any feedback would be
very appreciated.

If you are running HEAD you can just update and recompile.


It's not all pf fixes but all for today and I'd really feel better for MFCing
them in a couple of days if I get a couple of success reports;)
