i386 hack: caps vs ctl key

[Marco S Hyman <marc_(_at_)_dumbcat_(_dot_)_codewright_(_dot_)_com>]

I got tired of hitting the caps lock instead of the control key on
my portable when not running X.  This little hack is the result.
It makes the capslock a 2nd control key.  No guarantees, but it
seems to work for me.  This is for pccons.  The patch to pcvt is
quite similar.

To use, add

option          CAPSCTL         # make caps-lock an additional control key

to your configuration file and remove

	XkbOptions      "ctrl:swapcaps"

from your /etc/XF86Config (if it is there).
