allow mapping of blitter registers

make gftfb_restore_palette() grab the default colour map from rasops instead
of just writing the driver's map into the hardware ( which may have been
modified by the likes of wsfb )
With this we get a readable console even when exiting X in a less than
graceful manner.

For some reason the drawing engine occasionally scribbles past the right
boundary when filling rectangles, especially annoying when we draw whitespaces
As a workaround we draw all rectangles less than 50 pixels wide by drawing
a 50 pixel rectangle into off-screen memory to the right of the visible fb and
then copy the portion we want. Keeps track of the colour and size of the
off-screen rectangle so we can avoid redrawing it whenever possible.

fix brainfart - only update fbi_fbsize, not the size of the visible fb...

in gftfb_ioctl():
- identify ourselves as WSDISPLAY_TYPE_STI
- return full fb geometry in WSDISPLAYIO_GET_FBINFO

if the framebuffer is wider than the visible area, use the full width for the
glyphcache

support WSDISPLAYIO_SVIDEO so X can turn the monitor off
so far I only know how to turn off video output, not sync(s). Better than
nothing though.

add hardware cursor support, mostly for X

avoid one more instance of unnecessary blitter stalling

keep track of hw settings for blitter, fill of fb access to avoid unnecessary
register writes
while there, remove some accidentially left in debug goop

play the same lazy cursor (un)draw trick as cgsix and friends
visible speedup in things like systat

enable glyph cache, anti-aliased fonts etc.

blitter time!
everything except drawing characters i now done by hardware
next step - glyphcache
