Applied all relevant PCem commits;
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in the future); In some occasions (IDE hard disks in multiple sector mode and SCSI hard disks) the status bar icon is no longer updated, should improve performance a bit; Redid the way the tertiary and quaternary IDE controllers are configured (and they are now device_t's); Extensively reworked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.
