Fix for GitHub issue #73 - allow for island ports in vpi_put_value.
...
In the special case that a net is attached to an island port, values
driven onto the net via the VPI must go to the functor, not the filter,
so that they propagate through the island.

Fix various bugs in vpi_put_value.
...
When putting a value onto a wire, the value needs to be sent to the
filter, not the functor (the functor may be part of the expression
that drives the wire).
Force and release weren't implemented properly (or at all in the
case of real values). They need to behave the same as the force
and release operations in vthread.cc.

Fix propagation of unforced bits when forcing a part select.
...
vvp_net_t::force_vec4 propagates all bits of the forced value passed
to it, regardless of the mask value. I can't see any way to fix this
directly, so instead make sure anything that calls force_vec4 sets
the unforced bits of the passed value to the correct value.
