MFC r260261 (gavin):
Lower the priority of the "connect to any open wireless network" network
description, so guaranteeing that any other defined network will be tried
first.

MFC r260262 (gavin):
Allow bsdinstall to use WPA-Enterprise networks when installing. This
only allows basic username/password config, and does not provide the
ability to set any of the other WPA options. Regardless, this is
generally sufficient to associate.

Perhaps in the future this could allow full configuring (e.g. being able
to set "anonymous identity", and perhaps some of the more obscure WPA
options), though perhaps that will better belong in bsdconfig when that
grows wlan config ability.

MFC r260260 (gavin): Remove what appears to be a stray debugging printf.

Allow WPA PSKs up to 63 characters, the max length according to
wpa_supplicant.conf(5). Up to now, the PSK was truncated
to 15 characters (the length of the input field).

Check correctly for whether there are any available wireless networks. This
was tested on a train in the middle of an upstate New York swamp.

Import bsdinstall. This is meant to be (eventually in conjunction with
pc-sysinstall) a replacement for sysinstall in the 9.0 release and beyond.
Currently supported platforms are sparc64, pc98, i386, amd64, powerpc, and
powerpc64. Integration into the build system will occur in the coming
weeks.

Merging with pc-sysinstall will use this code as a frontend, while
temporarily retaining the interactive partition editor here. This work
will be done in parallel with improvements on this code and release
integration.

Thanks to all who have provided testing and comments!
