requested by uwe@. These were wrong because they were receiving an
emulcookie yet they were accessops (thus having to receive an accesscookie).
Instead, just handle the WSDISPLAYIO_{GET,PUT}WSCHAR ioctls from the
driver's ioctl accessop.
As this reduces the amount of code needed to handle these operations to
two small functions in each driver, remove the WSDISPLAY_CHARFUNCS kernel
option.
Reviewed by, at least, uwe@ and macallan@. No objections in tech-kern@.
* 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.
