9277e63302 Adding changes to ipfw and the kernel to support ip packet diversion..
This stuff should not be too destructive if the IPDIVERT is not compiled in..
 be aware that this changes the size of the ip_fw struct
so ipfw needs to be recompiled to use it.. more changes coming to clean this up.

edea64b844 Formatting fixes for 'in' and 'out' while listing.
Prevent ALL protocol from being used with port specifications.

Allow 'via' keyword at any point in the options list.  Disallow
multiple 'via' specifications.

3a18399d4f Fix address mask calculation when using ':' syntax. Allow a mask
of /0 to have the desired effect.  Normalize IP addresses that
won't match a given mask (i.e. 1.2.3.4/24 becomes 1.2.3.0/24).
Submitted by R. Bezuidenhout <rbezuide@mikom.csir.co.za>

Code formatting and "frag" display fixes.

9a01ae8a2a Big sweep over ipfw, picking up where Poul left off:
- Filter based on ICMP types.
  - Accept interface wildcards (e.g. ppp*).
  - Resolve service names with the -N option.
  - Accept host names in 'from' and 'to' specifications
  - Display chain entry time stamps with the -t option.
  - Added URG to tcpflags.
  - Print usage if an unknown tcpflag is used.
  - Ability to zero individual accounting entries.
  - Clarify usage of port ranges.
  - Misc code cleanup.

Closes PRs: 1193, 1220, and 1266.

eae8a60e05 Ok..so everybody picking on me that ipfw syntacs
is a pain in ...wel.. trying to fix this
 * from/to/via position indepenndant syntax
 * "any" for 0/0 host address
 * addf/addb default keyword in case you skip it..
 * pass = accept new action, seems to be somewhat better
   in particular cases
 * on = via (as on ed0 instead of via ed0,loook at
   reject tcp on ed0 from hacker )

c5bdd3a729 Fix for rather stupid bug by which you couldn't set
ports for the destination IP addr/port.
Nobody reported this btw , while a lot of other things reported-
probably ppl does not use destination ports at all????
