    Fix spool handling to allow call files to be hardlinked into place

    This fixes the inotify code to handle call files being hardlinked into the
    spool directory.

    The smsq utility does this, instead of rename(), to ensure that it cannot
    accidentally overwrite an existing spool file. A rename() might do that, but
    link() will definitely not.

    The inotify code had broken this, because it would wait for an IN_CLOSE_WRITE
    event on the file... which was never forthcoming, since it was never opened.
    Now we look for IN_OPEN events following the IN_CREATE event, and only wait
    for an IN_CLOSE_WRITE if the file was actually opened.
