jmmv 2a08d54a9a Implement border color customization in wscons(4), only available for vga(4) 
at the moment.

This includes the addition of two new wsdisplay ioctls, WSDISPLAY_{G,S}BORDER,
one to get the actual color and one to set it, respectively.  Possible colors
match those defined by ANSI (and listed in wsdisplayvar.h).

It also adds two accessops to the underlying graphics device, getborder and
setborder, which mach their ioctl counterparts.

Two kernel options are added: WSDISPLAY_CUSTOM_BORDER, which enables the
ioctls described above (to customize the border color from userland after
boot), and WSDISPLAY_BORDER_COLOR, which sets the color at boot time.
The former is enabled by default on the GENERIC kernel, but not on INSTALL
(among others).  The later is always commented out, leaving the usual black
border as a default.

wsconsctl is modified to allow accessing this value easily.  For example,
'wsconsctl -d -w border=blue'.
