Integrate the hostap stuff that Thomas Skibo <skibo@packbell.net>

wrote.  This code was for 4.5-release, so I've ported it to -current
and made a few minor tweaks.  The biggest non-style tweak was to not
make access point the default.

More changes will be needed to get this actually working, but I wanted
to get a relatively pure baseline.  This doesn't seem to break what
works now.
