hash: replace with cuckoo hash implementation

This patch replaces the existing hash library with another approach,
using the Cuckoo Hash method to resolve collisions (open addressing),
which pushes items from a full bucket when a new entry tries
to be added in it, storing the evicted entry in an alternative location,
using a secondary hash function.

This gives the user the ability to store more entries when a bucket
is full, in comparison with the previous implementation.
Therefore, the unit test has been updated, as some scenarios have changed
(such as the previous removed restriction).

Also note that the API has not been changed, although new fields
have been added in the rte_hash structure (structure is internal now).
The main change when creating a new table is that the number of entries
per bucket is fixed now, so its parameter is ignored now
(still there to maintain the same parameters structure).
The hash unit test has been updated to reflect these changes.

As a last note, the maximum burst size in lookup_burst function
hash been increased to 64, to improve performance.

app/test: decrease size of requested mempool

In test application, the default size of allocated mempool is calculated
as following:

  (RTE_MAX_LCORE * (RTE_MEMPOOL_CACHE_MAX_SIZE + max_kept_objects)) - 1

The objective is to ensure that all cores can fill their cache and keep
'max_kept_objects' at the same time. As RTE_MAX_LCORE is 128 and
RTE_MEMPOOL_CACHE_MAX_SIZE is 512 in the default configuration, it can
produce very large mempools (170 MB).

We can replace the number of core by a dynamic value, which drastically
reduces the amount of memory needed for this test (5 MB with 4 cores).
