- Change the fbuf "vga" parameter to "vga=on|io|off".

Browse Source 
"io" is the default, and allows VGA i/o registers to be
   accessed. This is required by Win7/2k8 graphics guests that
   use a combination of BIOS int10 and UEFI.
   "off" disables all VGA i/o and mem accesses.
   "on" is not yet hooked up, but will enable full VGA rendering.

   OpenBSD/UEFI >= 5.9 graphics guests can be booted using "vga=off"

- Allow "rfb" to be used instead of "tcp" for the fbuf VNC
  description. "tcp" will be removed at a future point and is
  kept as an alias.
