71afef2c14 apps: add mask-based hash functions
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).

2dc5198907 table: add unified params struct and mask-based hash func
Add unified parameter structure for all hash tables in librte_table.

Add mask-based hash function prototype, which is input parameter for
all hash tables.

Renamed the non-mask-based hash function prototype and all the calls
to it (to be removed later).

8aa327214c table: hash
Various types of hash tables presented under the Packet Framework toolbox.

Hash table types:
1. Extendible bucket (ext): when bucket is full, bucket is extended with
   more keys
2. Least Recently Used (LRU): when bucket is full, the LRU entry is discarded
3. Pre-computed key signature: RX core extracts the key n-tuple from the
   packet, computes the key signature and saves the key and key signature
   within the packet meta-data; flow classification core performs the actual
   lookup (the bucket search stage) after reading the key and key signature
   from packet meta-data
4. Signature computed on-the-fly (do-sig version): the same CPU core extracts
   the key n-tuple from pkt, computes key signature and performs the table
   lookup
5. Configurable key size or optimized for single key size (8-byte, 16-byte
   and 32-byte key sizes)
