Allow SimActors to produce/consume a constant stream of tokens

Currently a SimActor requires one clock period to recover from consuming or
producing a token. ack/stb are deasserted in the cycle where the token is
consumed/produced and only re-asserted in the next cycle. This patch updates the
code to keep the control signals asserted if the actor is able to produce or
consume a token in the next cycle.

The patch also sets 'initialize' attribute on the simulation method, this will
make sure that the control and data signals will be ready right on the first
clock cycle.

I.e. if the index is negative is acutal index used is len(l) + i. E.g. l[-2]
equals l[len(l)-2].

Being able to specify an index this way also comes in handy for migen slices in
