[CFR/T] multi-/no-IP jail patch for HEAD

Hi,

I have put a close to be commit candidate (if ipv4 src addr selection
is in upfront) online here:

 	http://people.freebsd.org/~bz/bz_jail-20080915-02-svn.diff

This is for HEAD, for review and testing.

Changes since last release:
- SCTP enabled (again) for IPv4 and on for v6 as well. Might need
   another pari of eyes or someone to write regression tests.
- jls -a/-v implemented/documented
- updated ipv4 source address selection (changes semantics, please
   test/review carefully)
- minor cleanup

Please report anything you want/that need sto be/... changed/fixed/...

Thanks.
/bz


PS: for anyone crying for RELENG_7. I am trying to put a patch
together the next days.
