Added the NCR 53C810 PCI SCSI controller;

Browse Source 
Fixed the behavior of the CD-ROM GET CONFIGURATION command when unimplemented features are requested;
Fixed the behavior of the CD-ROM READ DVD STRUCTURE command in some situations and made it correctly report 05/30/02 for incompatible format;
Reworked the PS/2 Model 80 Type 2 memory handling a bit;
The emulator now allocates the few MB of space needed for pages for the entire 4 GB RAM space at the startup and only memset's it to 0 on hard reset - should make sure DMA page reads from/writes to memory-mapped devices no longer crash the emulator on invalidating the memory range;
Applied app applicable PCem patches;
The PS/1 Model 2133 now also applies PS/2-style NMI mask handling - fixes the 486 recompiler on this machine;
Added the missing #include of "cpu/cpu.h" in io.c, fixes compiling when I/O tracing is enabled.
