93e0e11657 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.

97842144e3 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.

c06c129887 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>

b55b9e3f1d 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.

38a98b2254 Correct minor nit - to filter out SYN packets, the keyword is 
`syn' not `tcpsyn' (which matches `tcp' which blocks all tcp
packets)

9071ec3796 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 )
