Summary: This CL implements the checksumming functions. This departs from the current Scudo code in one aspect: the software version is no longer CRC32 but a BSD checksum. This is because the software CRC32 was too impactful in terms of performances, the BSD checksum has no array lookup which is better (and saves 1KB of data). As with the current version, we only flip the CRC compiler flag for a single compilation unit by default, to allow for a library compiled with HW CRC32 to work on a system without HW CRC32. There is some platform & hardware specific code in those files, but since departs from a mere platform split, it felt right to me to have it that way.
