8a4381b139 Add feature for tcp "established".
Change interface between netinet and ip_fw to be more general, and thus
hopefully also support other ip filtering implementations.

45a7f29691 Make getsockopt() capable of handling more than one mbuf worth of data.
Use this to read rules out of ipfw.
Add the lkm code to ipfw.c

37d6472c4f Big sweep over the IPFIREWALL and IPACCT code.
Close the ip-fragment hole.
Waste less memory.
Rewrite to contemporary more readable style.
Kill separate IPACCT facility, use "accept" rules in IPFIREWALL.
Filter incoming >and< outgoing packets.
Replace "policy" by sticky "deny all" rule.
Rules have numbers used for ordering and deletion.
Remove "rerorder" code entirely.
Count packet & bytecount matches for rules.

Code in -current & -stable is now the same.

5d0e3b6e78 Well..finally..this is the first part..it should take care of
matching IP options..Check and test this - i made only a couple
of rough tests and this could be buggy.. Ipaccounting can't use
IP Options (and i don't see any need to cound packets with specific
options either..)
More to come...

de86e24516 Fixed panic that occurs on certain firewall rejected packets that was
caused by dtom() being used on an mbuf cluster. The fix involves passing
around the mbuf pointer.

dd3cca2bda Actual firewall change.
1) Firewall is not subdivided on forwarding / blocking chains
   anymore.Actually only one chain left-it was the blocking one.
2) LKM support.ip_fwdef.c is function pointers definition and
goes into kernel along with all INET stuff.

e8b4c66232 Ugen J.S.Antsilevich's latest, happiest, IP firewall code.
Poul:  Please take this into BETA.  It's non-intrusive, and a rather
substantial improvement over what was there before.
