[net80211] add another hard-learnt lesson about DWDS setup

wlanwds monitors the physical interface for DWDS requests from VAPs,
but the clone is created against the physical interface. So, if you
have a secondary VAP setup (with a separate, non-physical-default MAC
address) which is configured for DWDS, the temporary DWDS VAPs created
will have the MAC of the parent physical interface and NOT the
actual cloned interface + MAC.

This .. stumped me for a few minutes.

Maybe I'll fix it. Maybe I won't. At least I now have DWDS+encryption
working at home.

Tested:

* yes, with DWDS 11n repeaters now working on freebsd.

[net80211] document having to enable privacy on the dynamic plumbed VAPs.

A new jail(8) with a configuration file, to replace the work currently done
by /etc/rc.d/jail.

Create the altix project branch. The altix project will add support
for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting
is a two-module system, consisting of a base compute module and a
CPU expansion module. SGI's NUMAFlex architecture can be an excellent
platform to test CPU affinity and NUMA-aware features in FreeBSD.

no more need for -p option to wlanwds; it knows how to find the parent now

- Import the HEAD csup code which is the basis for the cvsmode work.
