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.

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.

- The flags NETIF_F_HW_VLAN_* have been renamed to NETIF_F_HW_VLAN_CTAG_*.
See Linux commit f646968f8f7c624587de729115d802372b9063dd.
- The VLAN protocol must be specified.
See Linux commits 86a9bad3ab6b6f858fd4443b48738cabbb6d094c
and 80d5c3689b886308247da295a228a54df49a44f6.

This type of pseudo-device is needed for ring and pcap PMDs.
They are compatible with whitelist and are initialized in rte_eal_init().

The pause instruction is part of SSE2 extensions.
Note that some compilers define _mm_pause as "rep; nop" instead of "pause".
For compatible processors, they are equivalent.

"
When executing a spin-wait loop, a Pentium 4 or Intel Xeon processor suffers
a severe performance penalty when exiting the loop because it detects a
possible memory order violation.
The PAUSE instruction provides a hint to the processor that the code sequence
is a spin-wait loop. The processor uses this hint to avoid the memory order
violation in most situations, which greatly improves processor performance.

- timecompare (used for hardware timestamping) has been removed.
(see Linux commit 65f8f9a1c1db831e5159e3e3e50912d1f214cd0c)
Simply disable HW_TIME_STAMP feature because it is not used by KNI.
- annotations __devinit and __devexit have been removed.
