wpa: Fix a SIGBUS error in wpa_sm_set_rekey_offload

Incorrectly linked built-in wpa functions resulted in overwriting
sm->ctx->set_rekey_offload with garbage. It was initialized correctly
however it changed after wpa_supplicant became a daemon.

No SIGBUS violations reported by dhw@ were experienced during testing
of the original commit by msyelf or philip@.

wpa: Restructure wpa build

The current WPA build assumes a flat namespace. However the latest sources
from w1.fi now have a duplicate config.c, in two separate subdirectories.
The flat namespace will overwrite config.o with the output from the most
recently modified config.c, of which there are two of them.

This commit resolves this problem by building each component in
wpa's src subdirectory tree into its own .a archive, just as the w1.fi
upstream build as used by the port does. The advantages of this approach
are:

1. Duplicate source file names, i.e. config.c in the wpa_supplicant
direcory and another config.c in src/utils in the next wpa
will result in both compiles writing to the same .o file.

2. This restructure simplifies maintanence. A develper needs only to add
new files as identified by git status in the vendor branch to the
appropriate Makefile within the usr.sbin/wpa tree. This also reduces
time required to prepare a new import and should reduce error.

3. The new wpa build structure more closely represents the build as
performed by the upstream tarball.

This is in preparation for the next wpa update from w1.fi.

usr.sbin/wpa: complete the revert of wpa import

This completes the revert of b51f459a2098622c31ed54f5c1bf0e03efce403b.

Revert wpa import.

b51f459a2098622c31ed54f5c1bf0e03efce403b resulted in a mismerge
due to having to do a remerge because my tree was over a week out of
date. Changes that were made to fix the build were lost in the remerge
resulting in build errors that were fixed a week ago.

pkgbase: Add a FreeBSD-wpa package

Move the wpa related files from FreeBSD-runtime to a new package named
FreeBSD-wpa
The FreeBSD runtime is only intended to have everything for a working
FreeBSD installation and wpa isn't needed for that.

Convert usr.sbin to LIBADD
Reduce overlinking

wpa_cli does not use libedit anymore since version 1.0

Replace all uses of libncurses and libtermcap with their wide character

convert to using pidfile... This prevents multiple wpa_supplicants
running at the same time causing problems w/ wifi not working..

the patch will be submitted upstream... The next step if someone wants
to push it upstream is to break os_unix.c up so that all these other
utilities don't need libutil..

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.
