Improved 8042 (AT and PS/2 keyboard controller emulation), no more hacks, split into various devices depending on vendor (generic, AMI, IBM (MCA), Quadtel, Toshiba), and fixed several commands - hopefully fixes all existing AT+ keyboard problems (such as incorrect scan codes on some machine under some circumstances);

Fixed a bug in the SMC FDC37C932 emulation, fixes the FDC on the two Acer machines;
Re-added some Acer-specific I/O port handlers, fixes entry into CMOS Setup on the two Acer machines.
