migen/genlib/record: add leave_out parameter to connect

Modules doing dataflow adaptation often need to connect most of the signals between endpoints except the one concerned by the adaptation.
This new parameter ease that by avoid manual connection of all signals.

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.
