Kscd failed to do anything reasonable on my FreeBSD system w/ an ATAPI
cdrom drive.  The patches below fix the immediate problems such that I
can now play CDs, but things still aren't perfect.  Also, I have no
idea how these patches will affect SCSI cdrom support.

    - kscd segfaults if it can't find or open the CD device
      (no patch for this one)

    - play didn't work at all (patch to gen_play below - it seems
      that the initial CDIOCSTART is bogus, at least on ATAPI
      cdroms).

    - pressing stop leaves kscd locked up.  (patch below - it
      seems that the ATAPI cdrom returns CD_AS_PLAY_COMPLETED
      after a CDIOCSTOP ioctl, which caused kscd to hang waiting
      for the next track).

    - kscd doesn't cope with errors on the CD medium very
      gracefully, notably it claims the CD is ejected and
      won't do anything until the CD is forcibly ejected and
      re-inserted (no patch for this one).

Cheers,
	Simon
