Reverted EGA emulation to be in line with mainline PCem except for the overscan, as there were some problems;

Added write port 3C1 to EGA and (S)VGA, fixed Microsoft Word 2.0 for DOS;
The RTL8029AS now correctly enables I/O port range when base address is changed via PCI registers with I/O access enabled;
Tentative fix for DirectDraw <-> Direct3D switching issues based on proposal from TheCollector1995;
Fixed 64-bit makefile;
Fixed LZF_C.C so it can compile for 64-bit Windows;
Applied all mainline PCem commits.
