Replaced the Cirrus Logic code with the latest code from TheCollector1995 - the CL-GD 5428 is now fully working, as is the CL-GD 5429;
Minor clean-up in the AHA/BusLogic BIOS commands code;
Slightly rewritten mem_readb_phys_dma() and mem_writeb_phys_dma().
IBM.H is gone, video stuff re-organized. Keyboard stuff reorganized.
Machines that have their own video, mouse and/or keyboard now have all this in their machine file.
Fixed and other cleanups here and there.
Fixed (hopefully) pass through in the Windows CD-ROM IOCtl code;
Fixed the legacy I/O address handling on the BT-958D, now it behaves correctly - legacy I/O address disabled by default, can be enabled in AutoSCSI (removed the setting from the device config struct);
The BT-958D PCI-configured I/O space now correctly gets 32 ports and not 4.
Fixed MCA write bugs for the AHA-1640 and BT-640;
Fixed a warning in the PC87306 Super I/O chip emulation;
Each renderer now only has a 32-bit blitter - video_blit_memtoscreen_8() now only converts buffer to buffer32 and then calls video_blit_memtoscreen(), 8-bit blitters are now gone.
Fixed the MCA write function of the AHA-1640 MCA - the host ID is now read from the correct variable and the sync and parity check values are now read as well.
The CD-ROM and SCSI disk REQUEST SENSE commands no longer incorrectly set the phase to status;
REQUEST SENSE with non-data direction control byte is now treated as a request to send sense bytes from the command directly to the sense buffer;
SCSI and SLiRP threads now terminate themselves again when out of the while loop;
SCSI and SLiRP mutexes are now closed when the threads terminate themselves;
Fixed a bug causing the "Press F12+F8 or middle mouse button to release" string on the title bar to get corrupt.
Fixed AHA-154x scatter/gather transfers;
Two-phased SCSI read-direction commands;
Made scsi_bus.c use a dynamically malloc'd buffer instead of a giant fixed-size buffer;
The AHA-154x/BusLogic thread now uses mutexes;
The BusLogic BT-545C is now the BT-545S;
Added the BusLogic BT-542BH;
The AHA-1542CF now again uses the v2.11 BIOS as the CD booting now works;
Applied PCem commit that adds NMI support to the recompiler;
Applied PCem commit that adds the IBM XT 286;
Applied PCem commits that have to do with sound, including the ES1371;
Fixed the NCR5380 output data register;
Moved the SLiRP mutex stuff from win.c to the appropriate network files;
Added sanity checks to everything in win_thread.c.
Cleaned up the handlers for the BusLogic Execute SCSI Command command;
Made the AHA-1542CF use version 2.01 of the BIOS;
The CD-ROM GET EVENT STATUS NOTIFICATION fix is back.
The Settings dialog now correctly filters devices by bus;
Split the dual VLB/PCI graphics cards into VLB and PCI versions;
Device filtering is now done using the new device_is_valid() call that compares device flags to machine flags;
Moved the NCR-based SCSI controllers to the main branch;
Moved the NE1000 to the dev branch until it's finished.
Two-phases SCSI disk write direction commands (needed for the NCR5380);
Renamed cdrom_ioctl.c/h to win_cdrom_ioctl.c/h and moved them to win/;
Moved some CD-ROM and floppy initialization blocks to the appropriate files.
The IBM PS/2 Model 486 now uses its own rom set ID;
The AHA-154x and Buslogic SCSI controllers no longer stop scanning for mailboxes when in aggressive round robin mode;
PIC interrupt processing fixes - no more IRQ-caused triple faults in Windows 98 SE.
