- Moved DOS ASPI functionality to msdos/dosaspi.c.
- Got rid using PROFILE to get SCSI info from wine.conf.
- Read scsi info from /proc/scsi/scsi.
- Added setting of a reasonable timeout when opening a SCSI device (5
  minutes, defined in winescsi.h).
- ExecScsiCommand now ALWAYS posts, even on error (which is the correct
  behavior).
