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.

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.

bank: add re to CSRStorage
...
being able to know when a register is updated is useful in many cases and avoid having to handle another register for that.
re is asserted when the the last CSR of the Compound is written. Software must also write Compound in the right order.

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.
