This patchset makes two significant enhancements to the CRC modules of
the rte_net library:

1) Adds run-time selection of the optimal architecture-specific CRC path.
   Previously the selection was solely made at compile-time, meaning it
   could only be built and run on the same generation of CPU. Adding
   run-time selection ability means this can be used from distro packages
   and/or DPDK can be compiled on an older CPU and run on a newer CPU.
2) Adds an optimized CRC implementation based on the AVX512 and
   VPCLMULQDQ instruction sets.
   
For further details, please see the commit messages of the individual
patches.

v2:
* Added support for run-time selection of optimal architecture-specific
  CRC, based on v1 review comment.
* Added full working AVX512/VPCLMULDQD support for CRC32-Ethernet and
  CRC16-CCITT.

v1:
* Initial version, with incomplete AVX512/VPCLMULDQD support for
  CRC32-Ethernet only.
