Several bug fixes;
Preliminar addition of the SDL 2 renderer (does not yet work correctly in full screen mode);
SCSI devices no longer have configurable LUN's (this matches the configurability of real SCSI devices);
SCSI LUN's are now handed by the device's handler;
Removed all unused strings;
Removed some unused code files;
Significantly rewrote the bus mouse emulation.
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In some occasions (IDE hard disks in multiple sector mode and SCSI hard disks) the status bar icon is no longer updated, should improve performance a bit;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.
Slightly reworked the Cirrus Logic hardware cursor handler, it now loads the foreground and background colors from the special color palette;
Implemented Cirrus Logic SR 0x12 bit 7 that if set, makes the card use special color palette entry 2 for the overscan border color instead of attribute register 0x11.
The pages array are no longer allocated for the entire memory of space if memory size + 384 is above 16 MB (turns out it was not needed at all), further significantly reduces the emulator's RAM usage;
Made greatpsycho's revised SVGA status handling specific to ATI cards, while the generic (S)VGA code uses the old handling - fixes error 2401 on PS/2 Model 80.
Applied all the video-related PCem commits;
The keyboard ALT+TAB detection now sends one extra ALT key down and up, so the guest does not get stuck in a menu bar.
Removed the Mach64 ISA until someone finds a properly working BIOS;
Changed the Mach64 VLB to use the BIOS that actually works;
Moved the standalone TI CF62011 graphics card to the Dev branch until someone finds a BIOS for it;
Removed an accidental temporary change in win_dialog.c;
Reorganized the graphics card ID's to allow simplification of the MDA and VGA #define's in video.h;
Added a workaround for the TVGA8900D DAC sense, so the card is in color again.
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.
Changed the CD-ROM capabilities MODE SENSE page a bit;
Applied the S3 Trio and SVGA changes from PCem;
Fixed saving of the video renderer settings;
Fixed DirectDraw full screen;
Fixed crashes on soft reset in full screen.
Fixed the Force 4:3, Enable EGA/(S)VGA overscan, and Scale options;
Fixed a bug regarding register 0 of the SMC FDC37C665 Super I/O chip;
Commented out some excess logging.
