This module uses type conversion between struct and int.
Also truncation and comparison is used with this int.
It is not safe for different endian arch.
Add ifdef for big endian struct to fix this issue.

rte_hash structure should not be a public structure,
and therefore it should be moved to the C file and be declared
as internal. rte_hash_hash implementation is also moved
to the C file, as it uses the structure.
This patch also removes part of a unit test that was checking
a field of the structure.

Looking at the code, these warnings are invalid from my pov and they disappeared
when upgrading the toolchain to new version (8.0-4).
However, the code was buggy (sorting code is wrong), so fix this by using qsort
and adding a check on num_sizes to avoid potential out of bound accesses.
