Temporarily derive blackbox modules in hierarchy to evaluate port widths

Signed-off-by: Clifford Wolf <clifford@clifford.at>

Value of properties can be expression.

Example found in the 2007.03 Liberty Reference Manual that was also found
in the wild:

    input_voltage(CMOS) {
        vil : 0.3 * VDD ;
        vih : 0.7 * VDD ;
        vimin : -0.5 ;
        vimax : VDD + 0.5 ;
    }

Current implementation just parses the expression but no interpretation is done.
