Flip-flops are generally modelled in behavioural code using non-blocking
assignments. This change makes the synthesised code behave the same as
the behavioural code. It's a more realistic model of a real flip-flop
too, which will always have some clock-to-output delay.

Make .scope aware of return type, and extend %ret/vec4 operands
...
The .scope needs to be aware of return types so that the %call/vec4
function knows how to intialize the return value. We also need to
extend the %ret/vec4 to support writing parts of the return value.

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.
