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.

/*
* 86Box A hypervisor and IBM PC system emulator that specializes in
* running old operating systems and software designed for IBM
* PC systems and compatibles from 1981 through fairly recent
* system designs based on the PCI bus.
*
* Emulation of the Intel PIIX and PIIX3 Xcelerators.
*
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.

* PRD format :
* word 0 - base address
More cleanups. Split Compaq Deskpro off to separae file. Renamed PIIX files to intel_ prefix. Re-enabled Compaq machines; the Portable II works fine now.

Applied all relevant PCem commits; Extensively cleaned up and changed the CD-ROM code; Removed CD-ROM IOCTTL (it was causing performance and stability issues); Turned a lot of things into device_t's; Added the PS/1 Model 2011 XTA and standalone XTA hard disk controllers, ported from Varcem; Numerous FDC fixes for the PS/1 Model 2121; NVR changes ported from Varcem; The PCap code no longer requires libpcap to be compiled; Numerous fixes to various SCSI controllers; Updated NukedOPL to 1.8; Fixes to OpenAL initialization and closing, should give less Audio issues now; Revorked parts of the common (S)VGA code (also based on code from QEMU); Removed the Removable SCSI hard disks (they were a never finished experiment so there was no need to keep them there); Cleaned up the SCSI hard disk and Iomega ZIP code (but more cleanups of that are coming in the future); In some occasions (IDE hard disks in multiple sector mode and SCSI hard disks) the status bar icon is no longer updated, should improve performance a bit; Redid the way the tertiary and quaternary IDE controllers are configured (and they are now device_t's); Extensively reworked the IDE code and fixed quite a few bugs; Fixes to XT MFM, AT MFM, and AT ESDI code; Some changes to XTIDE and MCA ESDI code; Some fixes to the CD-ROM image handler.
