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.

AsyncFIFO would need versions of flush and level in each clock domain
plus some handshaking on double flush.
