The vvp_vector8_t constructor and destructor involve memory allocation
so it is best to pass these objects by reference as much as possible.
Also rework the resolver functor to only perform resolution after inputs
are in so that it doesn't get needlessly repeated. This eliminates many
resolve function calls, as well as activations throughout the net.
Also have the islands take more care not to perform resolution if the
inputs aren't really different.
This patch adds ifnone functionality. It does not produce an
error when both an ifnone and an unconditional simple module
path are given. For this case the ifnone delays are ignored.
This patch makes sure the delay is calculated correctly when only some
of the bits change and you are comparing against the initial (t0) value.
Basically you have to check the initial value against all the bits in
the new signal not just the first bit since the order that bits change
is not deterministic.
Cleanup klunky implementation of vpi_get/put_delays for modpath
objects. Remove some useless members.

Add support for accessing the modpath nodes via PLI,
and add support for the vpi_set_delays and vpi_put_delays
functions to set the delays on those paths.
