mk: do not generate LDLIBS from directory dependencies The list of libraries in LDLIBS was generated from the DEPDIRS-xyz variable. This is valid when the subdirectory name match the library name, but it's not always the case, especially for PMDs. The patches removes this feature and explicitly adds the proper libraries in LDLIBS. Some DEPDIRS-xyz variables become useless, remove them.

EXPORT_MAP := rte_hash_version.map
hash: remove deprecated function and macros The function rte_jhash2() was renamed rte_jhash_32b and macros RTE_HASH_KEY_LENGTH_MAX and RTE_HASH_BUCKET_ENTRIES_MAX were tagged as deprecated, so they can be removed in 2.2. RTE_HASH_KEY_LENGTH is replaced in unit tests by an internal macro for the memory allocation of all keys used. The library version number is incremented.

mk: add library version extension To differentiate libraries that break ABI, we add a library version number suffix to the library, which must be incremented when a given libraries ABI is broken. This patch enforces that addition, sets the initial abi soname extension to 1 for each library and creates a symlink to the base SONAME so that the test applications will link properly.

# all source are stored in SRCS-y
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.
