0d440d081c lib: fix missing includes in exported headers
Many exported headers rely on definitions found in rte_config.h without
including it, as shown by the following command:

 grep -L '^#include <rte_config.h>' -- \
  $(grep -Rl \
    $(sed -n '/^#define \([^ ]\+\).*$/{s//\1/;H;};${x;s/\n//;s/\n/\\|/g;p;}' \
      build/include/rte_config.h) \
    -- build/include/)

We cannot assume external applications will include rte_config.h on their
own, neither directly nor through a -include parameter like DPDK does
internally.

This not only causes obvious compilation failures that can be reproduced
with check-includes.sh such as:

 [...]/rte_memory.h:88:43: error: ‘RTE_CACHE_LINE_SIZE’ was not declared in
     this scope
  #define __rte_cache_aligned __rte_aligned(RTE_CACHE_LINE_SIZE)
                                            ^

It also results in less visible issues, for instance rte_hash_crc.h relying
on RTE_ARCH_X86_64's presence to provide dedicated inline functions.

This patch partially reverts the commit below and adds missing include
lines to the remaining files.

95908f5239 ip_frag: free mbufs on reassembly table destroy
The rte_ip_frag_table_destroy procedure simply releases the memory for the
table without freeing the packet buffers that may be referenced in the hash
table for in-flight or incomplete packet reassembly operations.  To prevent
leaked mbufs go through the list of fragments and free each one
individually.

91cd905af9 ip_frag: fix IP reassembly regression
After changing pkt[0] to pkt[], the example IP reassembly is not working.
It's weird because this change is fine. There should be no difference
between them.
As a workaround, revert this change.

347a1e037f lib: use C99 syntax for zero-size arrays
Exported header files used by applications should allow the strictest
compiler flags. Language extensions used in many places must be explicitly
marked or removed to avoid warnings and compilation failures.

The extension keyword is used whenever the C99 syntax cannot do it.

This commit prevents the following errors:

 error: ISO C forbids zero-size array `[...]'

4f8e575f89 ip_frag: fix bit-fields in ipv6 fragment extension
Previous implementation won't work on every environment. The order of
allocation of bit-fields within a unit (high-order to low-order or
low-order to high-order) is implementation-defined.
Solution: used bytes instead of bit fields.

216391fc3f ip_frag: remove inclusion of mbuf header
The ip_frag header file includes the mbuf header file, but it does not
need to do so as it only uses pointers to the struct rte_mbuf type, and
does not use any of the mbuf internals, nor any of the mbuf functions or
macros. Therefore the inclusion is unnecessary, and can be replaced by a
forward declaration of the mbuf type.

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

c0cddf03f1 ip_frag: disable ip fragmentation if mbuf refcnt is disabled
rte_ipv4_fragment_packet() and rte_ipv6_fragment packet()
call rte_pktmbuf_attach() to attach the segment of the original
packet to the segment of the new fragmented one. Such function
is not declared if RTE_MBUF_REFCNT is disabled, as it needs to
call rte_mbuf_refcnt_update, not declared either.

Therefore, the ipv4/v6 fragmentation libraries are disabled
in that situation.
