Subject: [PATCH] Discriminate between I/O pin and block pin in NetBuilder.

* Bug: In NetBuilder::setStartHook(), trigger the "move up" of
    global routing only when encountering RoutingPad of a macro
    block and *not* an I/O pin of the whole block (at the edge).
    Boils down to look if the RoutingPad is anchored on a Pin
    or a Segment (macro block).
