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In some occasions (IDE hard disks in multiple sector mode and SCSI hard disks) the status bar icon is no longer updated, should improve performance a bit;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.
