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In some occasions (IDE hard disks in multiple sector mode and SCSI hard disks) the status bar icon is no longer updated, should improve performance a bit;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.
The CD-ROM and Iomega ZIP drives now clear the error bit when the PACKET COMMAND command is issued, fixes the Iomega GUEST.EXE for DOS hang when run while the Iomega ZIP drive is empty.
The buffers are now memset'd to 0x00's on allocation;
The Iomega ZIP drive now issues an IRQ on receipt of the PACKET COMMAND command, fixes it on Windows 98 SE.
