d254f41817 Banshee/Voodoo 3 status returns busy when FIFO thread is busy, regardless 
of command/cmdfifo/render thread status. Fixes some 2D races where drivers
start to write to framebuffer while (final) 2D blit command is still
running.

2cf57ab8b2 If Banshee video overlay is full screen (as would be the case for

1915149391 Increase Banshee revision to 3, matching my real CL Banshee card. Removes 
the need for any fogTable hack, which is in any case inconsistently applied
by drivers and I think may only be needed on pre-production devices.

19a5dfa579 Added Voodoo Banshee emulation. 
Known issues :
- Tiled framebuffer layout is not yet implemented. This causes horizontal
  offsets in some 2D 16bpp stuff (eg FMV in Tomb Raider 2, UI in Expendable)
- Fog is broken and currently disabled for Banshee
- Possibly at least 1 race in 2D blitter emulation
- A few things not yet emulated - overlay filters, some (rarely used) 2D
  blitter functions
