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'.

Changes to allow machines which don't use text mode at the boot time to use generic VGA driver(s): - Allow VGA drivers to use wsfont instead of builtin font. - Add vga_reset() function, which will be called from MD consinit(), to put VGA into text mode. This function is enabled by options VGA_RESET.
