3a52e64742 lib: fix cache alignment of structures
Include rte_memory.h for lib files that use __rte_cache_aligned
attribute.

Consider the following code:

	struct per_core_foo {
		...
	} __rte_cache_aligned;

	struct global_foo {
		struct per_core_foo foo[RTE_MAX_CORE];
	};

If __rte_cache_aligned is not defined (rte_memory.h is not included),
the code compiles but the structure is not aligned... it defines the
structure and creates a global variable called __rte_cache_aligned.
And this can lead to really bad things if this code is in a .h that
is included by files that may or may not include rte_memory.h

fdf20fa7be add prefix to cache line macros
CACHE_LINE_SIZE is a macro defined in machine/param.h in FreeBSD and
conflicts with DPDK macro version.
Adding RTE_ prefix to avoid conflicts.
CACHE_LINE_MASK and CACHE_LINE_ROUNDUP are also prefixed.

fa363849d0 mbuf: move metadata macros to rte_port library
The metadata macros are only used by libs and apps using the rte_port
packet framework library, so move them to a header file there.

ea672a8b16 mbuf: remove the rte_pktmbuf structure
The rte_pktmbuf structure was initially included in the rte_mbuf
structure. This was needed when there was 2 types of mbuf (ctrl and
packet). As the control mbuf has been removed, we can merge the
rte_pktmbuf into the rte_mbuf structure.

Advantages of doing this:
  - the access to mbuf fields is easier (ex: m->data instead of m->pkt.data)
  - make the structure more consistent: for instance, there was no reason
    to have the ol_flags field in rte_mbuf
  - it will allow a deeper reorganization of the rte_mbuf structure in the
    next commits, allowing to gain several bytes in it

62814bc2e9 mbuf: rename RTE_MBUF_SCATTER_GATHER into RTE_MBUF_REFCNT
It seems that RTE_MBUF_SCATTER_GATHER is not the proper name for the
feature it provides. "Scatter gather" means that data is stored using
several buffers. RTE_MBUF_REFCNT seems to be a better name for that
feature as it provides a reference counter for mbufs.

The macro RTE_MBUF_SCATTER_GATHER is poisoned to ensure this
modification is seen by drivers or applications using it.
