Consistent use of 'override' for virtual methods in derived classes.
...
o Not all derived methods were marked 'override', but it is a great
feature of C++11 that we should make use of.
o While at it: touched header files got a -*- c++ -*- for emacs to
provide support for that language.
o use YS_OVERRIDE for all override keywords (though we should probably
use the plain keyword going forward now that C++11 is established)

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.

extract_reduce: Fix segfault on "undriven" inputs
...
This is easily triggered when un-techmapping if the technology-specific
cell library isn't loaded. Outputs of technology-specific cells will be
seen as inputs, and nets using those outputs will be seen as undriven.
Just ignore these cells because they can't be part of a reduce chain
anyways.
