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.
*
* This file is part of the 86Box distribution.
*
* Emulation of the Winbond W83877F Super I/O Chip.
*
MonsterCommit(tm) with typo-fixes, void-ness fixes, correct CaPs for directories, etc. No real code changes.

* Winbond W83877F Super I/O Chip
* Used by the Award 430HX
*
Removed the file pointer from the hdd_t struct; Partially split off the Logitech Serial Mouse emulation from Microsoft Serial Mouse; Slightly reworked serial port emulation (the two UART's are now device_t's, non-FIFO mode implemented and is now default, FIFO mode reimplemented from scratch so it's now actually correct); Added the emulation of the SiS 85c497 chip to the SiS 85c496/497 chipset; Bugfixes to the emulated Super I/O chips and made them all device_t's now.

The FDC is now a device_t, and the FDC code has been cleaned up; Merged floppy.c and fdd.c and renamed floppy_*.c (the floppy image format handlers) to fdd_*.c; Reading the AT or PS/2 keyboard controller status no longer clears the transmit timeout bit, fixes error 8601 (mouse error) on the IBM PS/2 Model 80; MMU translate and DMA physical reads and writes now go through _mem_exec instead of directly to ram[], should fix the last remaining problems with remapped mappings; Implemented the Sound gain dialog; Added the resource for the "New floppy image" dialog and the needed functions for the functionality of exporting the currently mounted floppy image as 86F, both of which should be finished in the next commit; Applied the CD-ROM fixes from the PCem commit; Added the "Keep ratio" option for full screen stretch.

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.

Removed the file pointer from the hdd_t struct; Partially split off the Logitech Serial Mouse emulation from Microsoft Serial Mouse; Slightly reworked serial port emulation (the two UART's are now device_t's, non-FIFO mode implemented and is now default, FIFO mode reimplemented from scratch so it's now actually correct); Added the emulation of the SiS 85c497 chip to the SiS 85c496/497 chipset; Bugfixes to the emulated Super I/O chips and made them all device_t's now.

The FDC is now a device_t, and the FDC code has been cleaned up; Merged floppy.c and fdd.c and renamed floppy_*.c (the floppy image format handlers) to fdd_*.c; Reading the AT or PS/2 keyboard controller status no longer clears the transmit timeout bit, fixes error 8601 (mouse error) on the IBM PS/2 Model 80; MMU translate and DMA physical reads and writes now go through _mem_exec instead of directly to ram[], should fix the last remaining problems with remapped mappings; Implemented the Sound gain dialog; Added the resource for the "New floppy image" dialog and the needed functions for the functionality of exporting the currently mounted floppy image as 86F, both of which should be finished in the next commit; Applied the CD-ROM fixes from the PCem commit; Added the "Keep ratio" option for full screen stretch.
