I was about to merge this patch but there are some issues that should
have been caught by the library maintainer...

It seems the intention is to have a public API (meaning external DPDK
apps) consumption.
Then the header must be exported via 'headers' in lib/hash/meson.build.
Besides, such API addition must be announced in the release notes.
And this API should be documented either in some doc/guides/ or at
least with doxygen (meaning that rte_hash_xor.h must be referenced in
doc/api/doxy-api-index.md).


Thanks.
