Martin K. Petersen 2341c2f8c3 block: Add T10 Protection Information functions
The T10 Protection Information format is also used by some devices that
do not go through the SCSI layer (virtual block devices, NVMe). Relocate
the relevant functions to a block layer library that can be used without
involving SCSI.
