add generic CRCEngine, CRC32, CRCInserter and CRCChecker
...
CRCEngine implements a generic and optimized CRC LFSR. It will enable generation of CRC generators and checkers.
CRC32 is an implementation of IEEE 802.3 CRC using the CRCEngine.
CRC32Inserter and CRC32Checker have been tested on an ethernet MAC.

In some cases we don't want to stall the input pipeline when the DMA is inactive, setting ack_when_inactive to True will enable acknowledge of data when the DMA is inactive.

Make memory ports part of specials
...
This is needed to handle cases where a single memory has ports
in two different modules, and one of these modules is subject
to clock domain remapping. The clock domain of the port in that
module only must be remapped.

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.
