60472b3a66 Add emulation of SCAMP DRAM controls. This primarily emulates the mirroring 
effects of the controller programmed to the wrong DRAM size, which is required
for the Commodore SL386SX to be able to detect memory size correctly.

- DMAPAD acts as an ILOAD mirror during ILOAD operations, same as SRCx
- Handle signed X coordinates better in blit operations
- Add more MMIO registers
- Don't fatal on ILOAD reads when blitter not busy
Fixes Windows XP with Mystique.
