Fix divide by zero in GCells of null size. 

* Bug: In Anabatic::GCell, when width and/or heigh is null, do not try to
    compute densities as it will trigger a divide by zero (and do not make
    much sense anyway).
* Change: In CRL Core, in cmos/alliance.conf, honor the ALLIANCE_TOP variable
    if it is found in the user's environement.
