d9dfa8d8d5 More ATI accel fixes and undocumented stuff. 
1. Apparently some stuff uses read-only port 0x86ee and expects it to return 0 while port 0xf6ee is an alias to 0x82e8, this should fix hangs in Majong 8514 using ATI's DOS drivers.
2. 8514 data available bits are reset properly when new parameters for a new command are installed (port 0xCEEE), fixes remaining hangs with some stuff.

979198d592 More ATI changes plus one IBM 8514/A fix: 
1. Made the 4 color mode (67h) work properly now, including its 4 schemes on all ATI cards that support said mode.
2. Shadow set now has a true purpose for 8514/A compatibility on ATI Mach8/32.
3. Non-ATI 8514/A used to not work before because of the dev->local variable was not being set to 0 in the ibm8514_init() function, now it's fixed.

524fd30c0c ATI Mach8/32 fixes regarding 1992 ATI Ultra drivers for Windows 3.1x: 
1. For some reason, background colors were always black under those drivers in 8bpp mode, added a tweak to fix it (as well as Clock colors).
2. Likewise for the red scrolling in pbrush or write, added a tweak to its bitblt read mask.
3. Don't call svga_recalctimings in the hdisp/vdisp ports directly, fixes screen size on said drivers without affecting other stuff.
