Victor Boivie a866228db1 dcsctp: Use third_party/crc32c for integrity check 
CRC32c is used in SCTP for integrity checking, and the
third_party/crc32c library (https://github.com/google/crc32c) which has
been optimized for SSE42 and arm64 and has a much faster fallback
implementation for other architectures.
