mbuf: rework check on mbuf freeing
Allow poll-mode drivers to maintain their own caches of mbufs, by allowing them
to check if it's ok to free an mbuf (to their local cache) without actually
freeing it back to the memory pool itself.

eal: new common macros added
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.

mk: rework cpu flags detection
For cases where the compilation microarchitecture is explicitly given, we
extract the cpu-flags to use from the compiler rather than hard-coding. This
means that we will only ever use instruction sets supported by the compiler,
rather than having a case where the uarch and the Intel DPDK both support a
given instruction-set, but the compiler does not.
In the case where 'native' uarch support is requested, the same mechanism is
also used to detect the instruction-sets supported

config: fix combined/shared lib
- Configuration for combined and shared library was only in the template
defconfig_x86_64-default-linuxapp-gcc.
- CONFIG_RTE_LIBNAME was in the wrong section
- RTE_LIBNAME had no quote in "C context" (include/rte_config.h)

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)

igb/ixgbe: 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).
