csjp 9757d6d2e3 This commit adds a shared locking mechanism very similar to the ... mechanism used by pfil. This shared locking mechanism will remove a nasty lock order reversal which occurs when ucred based rules are used which results in hard locks while mpsafenet=1. So this removes the debug.mpsafenet=0 requirement when using ucred based rules with IPFW. It should be noted that this locking mechanism does not guarantee fairness between read and write locks, and that it will favor firewall chain readers over writers. This seemed acceptable since write operations to firewall chains protected by this lock tend to be less frequent than reads.
