Subject: [PATCH] GdsDriver now export correctly I/O pin (for FlexLib).

* In CRL::GdsStream::operator<<(Cell*), when encountering an *external*
    component, try to find a ".pin" layer associated (if not already
    in it). Then drive the BOUNDARY & TEXT in it. This way, Cadence/
    Calibre seems to be able to recognize them as Pin.
