This patch adds a new auto-test for testing the scaling
of concurrent inserts into rte_hash when protected by
the normal spinlock vs. the spinlock with HTM lock
elision. The test also benchmarks single-threaded
access without any locks.

Jenkins hash function was developed originally in 1996,
and was integrated in first versions of DPDK.
The function has been improved in 2006,
achieving up to 35% better performance, compared to the original one.
This patch integrates that code into the rte_jhash library.
It also updates the precalculated hash values in the unit test,
as the code now returns different values (expected).
A final note has been added in release notes for stating
the changes made.

In order to make sure that the hash functions are returning
the correct values, new tests have been added:
- First test compares precalculated hash values with values calculated
from the existing hash functions.
- Second test compares values returned from rte_jhash2 and rte_jhash,
expecting same return (only for multiple of 4 bytes keys)

Each test requires a certain minimal amount of memory.

Latest mbuf changes (priv_size addition and related fixes)
exposed small problem with testpmd and few other sample apps:
when mbuf size is exaclty 2KB or less, that causes
ixgbe PMD to select scattered RX even for configs with 'normal'
max packet length (max_rx_pkt_len == ETHER_MAX_LEN).
To overcome that problem and unify the code, new macro was created
to represent recommended minimal buffer length for mbuf.
When appropriate, samples are updated to use that macro.

To use rte_pktmbuf_pool_init(), the user can either:
- give a NULL parameter to rte_pktmbuf_pool_init(): in this case, the
private size is assumed to be 0, and the room size is
mp->elt_size - sizeof(struct rte_mbuf).
- give the rte_pktmbuf_pool_private filled with appropriate

To initialize a structure with zeros, one field was explicitly set
to avoid "missing initializer" bug with old GCC (e.g. 4.4).
This warning is now disabled (commit <insertlater>) for old versions of GCC,
so the workarounds may be removed.
These initializers should not be needed for static variables but they
are still used to workaround an ICC bug (see commit b2595c4aa9).
There is one remaining exception where {0} initializer doesn't work cleanly,
even with recent GCC:
lib/librte_pmd_ixgbe/ixgbe_rxtx_vec.c:735:9:
