0292be4a38 tridentfb: add imageblit acceleration for Blade3D family
Add imageblit acceleration for the Blade3D family of cores.  The code is
based on code from the cyblafb driver.

It is a step toward assimilating back the cyblafb driver into the
tridentfb driver.  The cyblafb driver handles a subfamily of the Trident
Blade3d cores.

5cf138457a tridentfb: source code improvements
This patch contains general source code improvments:
 - more simple functions are inline
 - removes some meaningless output and the VERSION
   string as it is no use
 - eng_par is moved into the tridentfb_par
 - removed small section of code for CyberBladeXPAi1
   which is maybe right for only one resolution
   and refresh rate and is probably redundant now
 - other minor improvements

49b1f4b44b tridentfb: acceleration code improvements
This patch brings various acceleration improvements:
- set  copyarea/fillrect for non-accelerated framebuffer (fix)
- remove 15 bpp depth handling to simplify code as it hardly
  works (15 bpp handling was obviously missing in some switches)
- add fb_sync call and move waiting before accelerated function
  to make acceleration more asynchronous to cpu (few % of speed
  improvement)
- add cpu_relax() call in waiting loops
- make longer register names and name more registers
- move registers' definition to header
- general code improvements (shortening, simplifying)

0e73a47f09 tridentfb: improved register values on TGUI 9680
Improved values for some registers after Xorg Trident driver.  The main
problem was that values set by BIOS have been ignored.

This patch completely remove random pixels ("snow") on the TGUI 9680 and
9440 (not supported yet by the driver).  It does not help with the "snow"
on 3DImage and Blade3D cards.

There is also small improvement in timing calculations (hblank start and
vblank start)

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
