Fix Pin managment on north & east side of the cell abutment box.

* Change: In AnabaticEngine::setupPrerouteds(), take into account the
    number of Pins. Now consider a net containing multiple Pins and, at most,
    one segment as *non-routed".
      This case may specifically happens for nets with pins on the north
    and east side, which are slightly *inside* the abutment box (to be
    seen by the router) and draw with them their *outside* direct
    connection wire.
* Bug: In cumulus/plugins.chip.CoreWire, no longer put the north or
    east side external Pin *exacyly* on the abutment box but *one pitch*
    inside so they are correctly seens by the P&R (must be *inside*
    the area of a GCell).
