Add "dffinit -noreinit" parameter
...
Sometimes the FF cell might be initialized during the map process, e.g.
some FPGA platforms (Anlogic Eagle and Lattice ECP5 for example) has
only a "SR" pin for a FF for async reset, that resets the FF to the
initial value, which means the async reset value should be set as the
initial value. In this case the DFFINIT pass shouldn't reinitialize it
to a different value, which will lead to error.
Add a "-noreinit" parameter for the safeguard. If a FF is not
technically initialized before DFFINIT pass, the default value should be
set to x.

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 now only removes the head of the chain, relying on "clean" to delete upstream cells. Added "-allow-off-chain" flag, but it's currently ignored.

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.
