Massive overhaul to the Trident TGUI code:

Browse Source 
Implemented the Graphics Engine linear address from CRTC34-35, required by OS/2.
Implemented 0x21xx acceleration ports.
Implemented Bresenham Line accel command required by OS/2.
Implemented 0xb7fxx linear mapping.
Implemented basic PCI bios rom bar (9440 only).
Revamped Trident TGUI cursor code.
Temporarily removed threading from the code as it caused too many graphical glitches.
Slight improvements to the Recalctimings function.
Un-hardcode the vram mask from the PCI write BAR0 part.
