The constants are now where they belong... `dialog.subr'
I also went through bsdconfig(8) with a fine-tooth comb and made use of the
new "constants" everywhere.
I think it's a definite improvement.

I took a look at the bsdinstall networking stuff, and I wanted to run away.
Let's push that into the future.
It wasn't too hard to get those global exit codes deployed, so I did that,

eventually slated for a future release.
