    Replace some seeks forward with wtap_read_bytes() with a null buffer
pointer.

    If the seek forward is just skipping record content that's not
    (currently) interesting, use wtap_read_bytes() with a null buffer
    pointer; it catches short "reads" and requires less seeking, so it may
    work better when reading from a pipe.
