Improved the BusLogic incoming mailbox code;

Fixed the CD-ROM command READ DISC INFORMATION (0x51), fixes NetBSD crashing 86Box with segmentation fault when using the AHA-154x;
Added the CD-ROM command PAUSE/RESUME ALT (0xC2).
Previous CD-ROM sense is now correctly cleared when a REQUEST SENSE command is performed, fixes detection of disc change after setting the drive to empty first regardless of what bus is used for the CD-ROM.

Significantly rewrote parts of the AHA-154x and BusLogic emulation, NT 3.1 RTM and MS-DOS drivers now works correctly;
The function in cdrom.c to read data blocks from the disc now correctly advances the position of the sector to read in non-passthrough mode, fixes multiblock reads from directly mounted ISO's;
Both ATAPI and SCSI now always check for Unit Attention and Not Ready on command execution.
- Crash dumps now attempt to be created in the directory with 86Box.exe
