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.

Named events really should be expressed with PEIdent
...
objects in the pform,
Handle named events within the mix of net events
and edges. As a unified lot they get caught together.
wait statements are broken into more complex statements
that include a conditional.
Do not generate NetPEvent or NetNEvent objects in
elaboration. NetEvent, NetEvWait and NetEvProbe
take over those functions in the netlist.
