CRC32c CRC algorithm with the iSCSI polynomial (RFC 3385 and RFC 3720)

A 32-bit CRC (cyclic redundancy check) with a polynomial defined
by G. Castagnoli, S. Braeuer and M. Herrman in "Optimization of Cyclic
Redundancy-Check Codes with 24 and 32 Parity Bits", IEEE Transactions
on Communications, Vol. 41, No. 6, June 1993, selected for use with
iSCSI.

Used by btrfs, ext4, jbd2, NVMeoF/TCP, and iSCSI.
