sim: use Simulator as a contextmanager
...
__del__ garbage collector callbacks are too delicate. E.g. imported
modules can be garbage collected before the objects using them. Can't
use os.remove, socket.SHUT_RDWR...
* added a DeprecationWarning if a Simulator is garbage collected without
having its .close() called
* renamed all gc __del__ callbacks to close()
* implemented context manager hooks for Simulator. Use like
with Simulator(TestBench()) as s:
s.run()

...
group_by_target does not properly combine target groups if statements
are presented in the order:
({A}, statement1)
({B}, statement2)
({A, B}, statement3)
which returns groups:
({A, B}, [statement1, statement3])
({B}, [statement2])
This patch fixes group_by_target such that the resulting group is:
({A, B}, [statement1, statement2, statement3])

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.

Add support for negative slice indices
...
In python a negative indices usually mean start counting from the right side.
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
some cases. E.g. the following snippet can be implement to shift an abitrary
length register n bits to the right:
reg.eq(Cat(Replicate(0, n), reg[-n:])
