    Make pdfimage devices work on Linux
    
    Because the devices usurp the FILE * created by the gdevprn code and
    turn it into a stream, we must set the stored pointer to NULL after
    closing or freeing the stream in order to avoid gdev_prn_close()
    attempting to close the underlying file again, which causes an error
    on Linux.
    
    Also remove some routines we no longer use.
