Florent Kermarrec 33c3a927c2 actorlib/structuring: add Pipeline
Pipeline enables easy cascading of dataflow modules.
DataFlowGraph can eventually use it to implement the
add_pipeline method to avoid duplicating things.

Florent Kermarrec 8db549a23d actorlib/structuring: add Converter
Converter enables easy conversions of data width on dataflows.
It handles the 3 possibles cases:
- downconverter
- upconverter
- direct connection when data width are identical.

Florent Kermarrec e03091e7e2 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.

Florent Kermarrec e0e99ec385 actorlib/spi: add ack_when_inactive parameter to DMA Write Controller
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.

Sebastien Bourdeauducq 1209ec17f6 actorlib/fifo: rewrite
* use classes for less code duplication
* the idea of decorator is to avoid passing common parameters (e.g. clock domain names) in module constructors, so remove those parameters
* style

Sebastien Bourdeauducq bac62a32a9 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.
