  Log:
  - Fix a bug in sysinstall related to mounting CD-ROMs.  If mount(2) fails
    with EBUSY and a cdrom is not mounted at /cdrom, sysinstall fails to
    treat it as an error and thinks that the disk mounted ok.  However, it
    doesn't find a cdrom.inf file so it complains.  Later when it tries to
    unmount the disk due to a mediaClose() umount(2) returns an error, and it
    never clears its internal mounted flag.  The fix here is to properly
    handle EBUSY as an error if there isn't a CD already mounted at /cdrom.
  - Add a new CDROMInitQuiet variable that can be used to shut up the dialog
    box about the mount(2) system call failing when trying to mount a CD-ROM.
    This is used by the feature described below.
  - When using a fixit CD, first try to see if we can mount the disc in the
    drive now and use it as a fixit CD.  If not, then prompt the user to
    insert the disc and try again.  If we do succeed on the first "silent"
    probe then we don't ask the user to eject the disk after leaving fixit
    mode.
  - Add a simple file existence test to make sure that the disc that we mount
    really is a livefs disc.
  - Explicitly switch back to ttyv0 when using the standard console after
    the fixit shell dies.  Previously this behavior worked accidentally
    because all the fixit modes popped up a dialog box which contained a
    hidden switch to ttyv0.
