Phase 1 of re-working the configuration system. All variables are now in a single structure (well, will be) and code will be updated in phases. Left are FDD, DISK, CDROM, ZIP and Joystick.
Updatd mem.c with new readmem386l and writemem386l functions from 86Box.
Several cleanups to the keyboard layer to remove some weirdness.
Updated the NVR code and nvr_at.c to just use a speed_changed member for the AT devices.
Added presetting a filename for NVR (so cards can use that.)
Updated some more translation files for STR_3480 and STR_3481.
Added a new card: ISA-based Clock/RTC cards for PC/XT systems.
Un-did previous change to XT ST506 driver.
Cleaned up parallel ports.
Reworked serial ports as devices (still need to clean the chipsets..)
Fixed some issues in Makefile.local.
Prepared for the XTA driver.
Reworked the mouse code AGAIN, fixes crashes on some serial mice and the PS/2 mouse.c
Cleaned up win_devconf.c.
Important change to the NVR code to "fix" the PS/1 and PS/2 systems, plus a cleanup.
All device tables now end with a NULL, not an empty string.
Configuration code now deals better with this.
Machine and Video lookup now return -1 if not found/available, and pc_init() will throw the user into Setup if that is the case.
If for some reason the configured memory size exceeds machine limit, it is now adjusted.
Cleaned up and re-integrated the Toshiba T1000/T1200 machines.
Moved LZF files to floppy/, as that is the only module using them.
Various bugfixes and cleanups here and there.
