the Nexus, to improve cprop performance.

Change the NetAssign_ class to refer to the signal
...
instead of link into the netlist. This is faster
and uses less space. Make the NetAssignNB carry
the delays instead of the NetAssign_ lval objects.
Change the vvp code generator to support multiple
l-values, i.e. concatenations of part selects.

Move inital value handling from NetNet to Nexus
...
objects. This allows better propogation of inital
values.
Clean up constant propagation a bit to account
for regs that are not really values.

Carry strength values from Verilog source to the

pform and netlist for gates.
Change vvm constants to use the driver_t to drive
a constant value. This works better if there are
multiple drivers on a signal.
