- use a uniform mtag format for all packets that exit and re-enter the firewall in the middle of a rulechain. On reentry, all tags containing reinject info are renamed to MTAG_IPFW_RULE so the processing is simpler. - make ipfw and dummynet use ip_len and ip_off in network format everywhere. Conversion is done only once instead of tracking the format in every place. - use a macro FREE_PKT to dispose of mbufs. This eases portability. On passing i also removed a few typos, staticise or localise variables, remove useless declarations and other minor things. Overall the code shrinks a bit and is hopefully more readable. I have tested functionality for all but ng_ipfw and if_bridge/if_ethersubr. For ng_ipfw i am actually waiting for feedback from glebius@ because we might have some small changes to make. For if_bridge and if_ethersubr feedback would be welcome (there are still some redundant parts in these two modules that I would like to remove, but first i need to check functionality).
