map: Adds a user configurable dont_use flag to liberty 
This flag (-X <glob>) will allow a user to set this flag
multiple times with a glob pattern to exclude cells that
user doesn't want to show up in a mapped netlist.

QuantamHD f288c4d7f6 Fixes internal pin parsing error in ASAP7 liberty file. 
This fix addresses an issue I saw with the ASAP7 liberty files and
ABC. ASAP7 lists internal pins in its liberty file which ABC's liberty
parser doesn't account for. This causes an assert to be triggered. This
fix simply adds interal pins to the ignore list.

Staf Verhaegen e4875df4e5 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.
