Prefix all Cell from a GDS file with "gds_" to avoid cell overload. 

* Bug: In CRL::GdsParser, the PLL was using copies of the standard cell
    with the same name. And unfortunately, they where found *before*
    the FlexLib one when using DataBase::getCell(). As their I/O where
    wrong it was leading to a massive netlist connexion corruption in
    blif2vst.
      To avoid that, any Cell created by the GDS parser is now prefixed
    by "gds_".
* Change: In CRL::GdsStream CTOR, report when the file cannot be opened
    instead of saying that the GDS file is corrupted (misleading).
