Add dedicated parameter structure for cuckoo hash. The cuckoo hash from
librte_hash uses slightly different prototype for the hash function (no
key_mask parameter, 32-bit seed and return value) that require either
of the following approaches:
1/ Function pointer conversion: gcc 8.1 warning [1], misleading [2]
2/ Union within the parameter structure: pollutes a very generic API
parameter structure with some implementation dependent detail
(i.e. key mask not available for one of the available
implementations)
3/ Using opaque pointer for hash function: same issue from 2/
4/ Different parameter structure: avoid issue from 2/; hopefully,
it won't be long before librte_hash implements the key mask feature,
so the generic API structure could be used.

Introduce mask-based hash functions in hash_func.h.
Propagate their usage in test/test, test/test-pipeline and
examples/ip_pipeline.
Remove the non-mask-based hash function prototype from API (which
was previously used as build workaround).

This is to logically group unit tests into their own folder,
separating them from "app" folder.
Hopefully this will make the unit test in DPDK more visible.
Following binaries moved to "test" folder:
cmdline-test
test-acl
test-pipeline
test <-- various DPDK unit tests
