Bunch of changes to wscons in preparation for splash screen support:

Browse Source 
* Add WSDISPLAY_TYPE_VESA for vesafb. While here, fix a typo in a comment.
 * Add WSDISPLAYIO_SSPLASH and WSDISPLAYIO_SPROGRESS ioctls. The former
   toggles the splash screen on and off, and the latter updates the progress
   animation.
 * Prevent more than one hw driver from claiming to be the console.
 * In vcons, keep two pointers to the screen's vcons_data. This lets us
   override the original (ie with null emulops during boot), and restore
   them later on.
