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In some occasions (IDE hard disks in multiple sector mode and SCSI hard disks) the status bar icon is no longer updated, should improve performance a bit;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.
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 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 buffer is now dynamically malloc'd;
Did a lot of bugfixing in cdrom.c and scsi_disk.c, Debian 8's modprobe aha1542 and the NT 3.10.404.1 Trantor 310b driver now work;
Fixed the IDE IRQ/MIRQ mess and ATAPI DMA transfer length;
Fixed the operation of mmutranslate() a bit;
Commented out several instances of excess logging;
Applied the mainline PCem commit prefetch commit;
Readded missing Sound Blaster DSP MIDI behavior and gave it the correct MPU struct;
All non-IBM 486 machines now correctly have the VLB flag set.
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.
