Split generic CD-ROM from SCSI-style CD-ROM;

Redid the way SCSI and ATAPI devices are handled;
Slight timings change in the NCR 5380;
Devices are now closed by device_close_all() in the reverse order of the one in which they were started;
Slight changes to some code in win/;
Added the WM_HARDRESET and WM_SHUTDOWN window messages for configuration manager purposes.
