Added my name to all the emulator's files that I touched; Unfinished JEGA emulation based on akm's DOSVAX (AX-emulating fork of DOSBox), not yet hooked into the reset of the emulator.

* PC systems and compatibles from 1981 through fairly recent
* system designs based on the PCI bus.
*
* This file is part of the 86Box distribution.

Another massive cleanup run. Ibm.h no longer includes system header files. ROM loading simplified, and moved from mem.c to rom.c. Fixes in Makefile. Corrected mamy wrong includes. Removed old junk from days long gone. First phase of new SCAT chipset driver - no longer gives errors in BIOS, but NOT DONE YET.

CD-ROM images are now working correctly again; Fixed all the reported bugs regarding the Settings dialog; MIDI out device is now no longer reset to 0 after hard reset; Removed all vestiges of the old disk activity flash; The configuration file is no longer saved when it shouldn't be; Redone the status bar icon updating so it is only done in win.c; Made sure all variables in ibm.h are extern; A lot of other bugfixes; Added Mouse Systems Mouse emulation (patch from TheCollector1995); Added IBM PS/1 Model 2133 (486) emulation (patch from TheCollector1995); Tweaked the CPU dynamic recompiler cycle periods - 486SX 33 and 486DX 33 now work; Increased compatibility with configuration files from before the previous commit.

Rewritten parts of the 86F handler to minimize false CRC errors and misidentification of sectors; Replaced IMG handler with one that now proxies to the 86F handler; Applies the remaining Mainline PCem speedup commit; Fixed the National Semiconductors PC87306 Super I/O Chip's serial port IRQ assignment; DMF images are now loaded with the correct sector interleave, improving read/write speed; XDF images are now loaded in a way that emulates the real order of the sectors on the track, improving read/write speed; Added 16-bit physical memory read/write routines (mem_phys_readw, mem_phys_writew) and modified the 16-bit DMA code to use them instead of two 8-bit reads/writes.

Vastly overhauled the UI, there's now a completely new Settings dialog as well as a status bar with disk activity icons and removable drive menus; Thoroughly clean up the code to vastly reduce the number of compiler warnings and found and fixed several bugs in the process; Applied all mainline PCem commits; Added SCSI hard disk emulation; Commented out all unfinished machines and graphics cards; Added the AOpen AP53 and ASUS P/I-P55T2 machines as well as another Tyan 440FX machine, all three with AMI WinBIOS (patch from TheCollector1995); Added the Diamond Stealth 3D 3000 (S3 ViRGE/VX) graphics card (patch from TheCollector1995); Added the PS/2 XT IDE (AccuLogic) HDD Controller (patch from TheCollector1995); Added Microsoft/Logitech Bus Mouse emulation (patch from waltje); Overhauled the makefiles (patch from waltje); Added the Adaptec AHA-1542CF SCSI controller (patch from waltje); Added preliminary (but still unfinished) Adaptec AHA-154x SCSI controller BIOS support (patch from waltje); Added an ISABugger debugging device (patch from waltje); Added sanity checks to the Direct3D code.
