from headers.

Added the following new macros/inline functions, which are both
generally useful and needed for later functionality:
* rte_align64pow2: aligns a 64bit parameter to next power of 2
* RTE_LEN2MASK: create mask of type <tp> with the first <ln> bits
* RTE_DIM: return the number of elements in an array.

The rte_ring functions used a compiler barrier to stop the compiler
reordering certain expressions. This is generally useful so is moved
to the common header file with the other barriers.

A static list of 64 mbufs was being reused in Rx function.
This caused two errors:
1) If more than 64 buffers were requested in a single burst,
only the last 64 buffers are returned, the others are lost.
2) Application will free the mbuf being returned, but the receive
function will reuse the buffer anyway. If some other allocation
is done, there is suddenly multiple writers for the same mbuf.
It is fixed by allocating mbuf on demand.
In the same time, some length errors are fixed.

Index overflow when resetting big queues was partially fixed in
bcf457f8c0d64a5c (ixgbe: fix index overflow when resetting big Tx queues)
and better fixed in
e8ae856140bce4e4 (igb/ixgbe: fix index overflow when resetting big queues)
But this version (1.5.2r0) has residues of the initial fix from 1.5.1r0.

ICC requires an initializer be given for the static variables,
so adding one in cases where one wasn't previously given.
This problem was introduced in commit e8ae856140bce4e
(fix index overflow when resetting big queues).

Rings are resetted with a loop because memset cannot be used without
issuing a warning about volatile casting.
The index of the loop was a 16-bit variable which is sufficient for
ring entries number but not for the byte size of the whole ring.
The overflow happens when rings are configured for 4096 entries
(descriptor size is 16 bytes). The result is an endless loop.
It is fixed by indexing ring entries and resetting all bytes of the entry
with a simple assignment.
The descriptor initializer is zeroed thanks to its static declaration.
There already was a fix for ixgbe Tx only
(commit bcf457f8c0d64a5cb094fd55836b324bddb930b6).
It is reverted to use the same fix everywhere (Rx/Tx for igb/ixgbe).

KNI must not do hardware reset. But it was resetting X540 devices.
This bug was in the first KNI version
(commit 3fc5ca2f63529ec5ad7b1b75f517d61dc7613bd9).

The base driver supports more NICs:
- i210 flashless
- i217
- i218
- i354
The new features are not automatically used by the DPDK PMD.
