Fix previous change that does not work on little endian machines.
Use inline call ip4_is_fragment() which is endian neutral.

Some small fixes to the srv6 code to bring it toward
conformance with draft-previdi-6man-segment-routing-header-05.
- The first segment needs to remain in the segment list.
- The segment list template needs a space for the ultimate
destination.
- The ultimate destination needs to be inserted into that
space when adding the SRH.

The add_del function was not properly checking if a tunnel already
existed; instead it was checking if the given tunnel name existed.
If no tunnel name was given it flat out refused to add a tunnel
even though that is optional.
Cleanup the add/del parameter validation to "do what I expect" it
to do:
When adding a tunnel:
- If a "name" is given, it must not exist.
- The "key" is always checked, and must not exist.
When deleting a tunnel:
- If the "name" is given, and it exists, then use it.
- If the "name" is not given, use the "key".
- If the "name" and the "key" are given, then both must point to the
same thing.

Before VPP is enhenced to do IP reassembly of local packets, just set
the protocol path to "experimental" for now so they will be error-punted
as unknow IP protocol.

When creating VXLAN over IPv6 the code was using storage for the
hash key that could later be moved. Since the key is larger than
the word size this was being referenced as a pointer; when the
storage moves that breaks the hash.
Instead allocate dedicated storage for the key.
This patch also includes other minor cleanups, including using
clib_memcpy in places it should be used and some whitespace
fixes.

The loopback interface should use vnet_interface_output_no_flatten so
follow-on buffers of a jumbo packet do not get put on the output frame
and be sent back to ethernet-input or l2-input node.
The replication_recycle_callback() function should not assume follow-on
buffers of a jumbo packet are on the buffer free list.

- consistent use of hash_*_mem methods.
- tunnel setup copies the key from the wrong location
- remove extraneous storage for keys copied from the vxlan

When af_packet signals the kernel that there are packets in the tx
ring with sendto() the kernel sometimes responds with EAGAIN.
Previously the af_packet driver would treat any error from sendto()
as fatal.
Whilst there's not much we can do about this, count the errors
and let's try to not die on the spot or sit in a loop forever.

succeeds, the newly created interface name is printed-out.
The patch includes the following interfaces types:

- Vhost User
- Netmap
- GRE
- L2TP
- MPLS-GRE
- Loopback

* compiler -march= parameter is changed from native to corei7
so code is always genereted with instructions which are available
on the Nehalem microarchitecture (up to SSE4.2)
* compiler -mtune= parameter is added so code is optimized for
corei7-avx which equals to Sandy Bridge microarchitecture
* set of macros is added which allows run-time detection of available
cpu instructions (e.g. clib_cpu_supports_avx())
* set of macros is added which allows us to clone graph node funcitons
where cloned function is optmized for different microarchitecture
Those macros are using following attributes:
__attribute__((flatten))
__attribute__((target("arch=core-avx2)))
I.e. If applied to foo_node_fn() macro will generate cloned
functions foo_node_fn_avx2() and foo_node_fn_avx512() (future)
It will also generate function void * foo_node_fn_multiarch_select()
which detects available instruction set and returns pointer to the
best matching function clone.

It appeared to me that it might be usefull
to allow users to create fibs or bridge domains without
a complete knowledge of the current used IDs.
These changes define fib and bridge domain constructors
when the provided ID is ~0. In such a case, an unused ID is
used to create a new fib or bridge domain.

When inserting routes into ip4/6 fibs, we first added a dummy adjacency
and afterwards manually updated its rewrite header to enable src/dst
forwarding. The downside to this is that the adj signature is changed
and therefore when deleting a route the adjacency signature is not
removed from adj_index_by_signature hash resulting in crash if the same
adjacency is re-inserted.
This patch avoids the issue by enforcing the insertion of 'complete'
adjacencies thereby obviating the need to update the rewrite header.

If a GRE tunnel is created, no other interface added and the GRE tunnel
is not set "up" then a crash occurs on the first packet for this tunnel
because fib_index_by_sw_if_index[] does not yet have a mapping to the fib
the new interface is in. The code to set this is missing from
gre/interface.c

The GRE code is missing the logic to indicate the "hardware" interface
is up. The fix is to listen for admin up/down events on the "software"
