gre: add missing .api edits

The previous edit has added a new field to a typedef.
That change is backward-compatible for PAPI users,
but not backward compatible for direct binary API users.

This change adds two edits that should have been there already:

+ Copyright year bump.
+ API version bump.
  - PAPI users point of view, so bumping minor version only.

nat: in2out-output nodes work with acl reflect

Type: feature

The current feature ordering of NAT44 nodes with respect to the
ACL plugin's IPv4 input/output features is:

ip4-output: acl-plugin-out-ip4-fa runs before any NAT44 nodes
ip4-unicast: acl-plugin-in-ip4-fa runs before any NAT44 nodes

ACL rules with action permit+reflect can keep track of outbound
flows and allow the replies inbound without an explicit inbound rule.
If ACL permit+reflect rules are configured on an interface that also
has NAT44 configured with output-feature/postrouting translation of
outbound packets, the ACL rules cannot allow inbound packets. The
ACL state that was stored on the outbound flow contains the IP
addresses of the original packet, prior to translation. The inbound
packets are being evaluated by the ACL node using the translated
addresses.

The order of processing inbound needs to be the opposite of what it
was outbound for this to work. Change the NAT44 features on
ip4-output so that they run before outbound ACL nodes. This matches
the existing behavior of the NAT44 nodes which rewrite
source addresses as an input feature instead of an output feature.

This was only done for endpoint dependent mode because the regular
endpoint independent in2out-output node currently selects an
explicit next node rather than using the next node on the feature
arc.

Unit test added to configure both NAT and an ACL and ensure that
out2in packets matching an in2out flow are permitted by the ACL
and translated by NAT.

fib: FIB crash removing labelled route (VPP-1818)

Type: fix

The crash occured trying to retreive a NULL path list to walk the path
extensions. A walk shoul not be required, because there should be no
extensins, since all paths are removed. The problem is that when the
paths were added, they were not sorted, hence neither were the
extensions and when they were updated, duplicate extensions were added,
and hence a path removal did not remove them all.
Fix is to make sure paths are sorted.

misc: binary-api sw_interface_vhost_user_dump is broken

Recent modificaton to vhost_user APIs for typing which added a sw_if_index
filter to the API sw_interface_vhost_user_dump with the default value -1 to
mean all interfaces. But the default is not set from api_format.c, causing the
binary-api command for sw_interface_vhost_user_dump to display nothing.

Also missing is the proper display on custom dump for the aformentioned API.

srv6-mobile: Revert "srv6-mobile:"

This reverts commit 57584d99dd8a8524db90c67c88525d58879d9b8e.

The reasons for reverting:

- the documentation seems "work in progress". Also, 500K of pngs
  should probably go on wiki, rather than in the repo. Please
  make sure that newly added documentation renders correctly
  and sensibly as part of the review/commit process.

- runner.py seems to contain unit tests, so it should
  be rewritten in a manner that allows the testing from within
  CI (including an unprivileged docker container)

- the above items, especially the testing one, warrant more
  work, and at a RC1 milestone time it is probably not
  a good idea to include a significant patch without
  proper care. I suggest to prepare it so it is ready
  for the next release, or cherrypick it for a
  20.01.1 release, if having it in stable/2001 is absolute necessity.

- when submitting it, ensure that the commit message
  makes sense, especially having "srv6-mobile:" with no further
  text should be absolutely avoided.

ip: avoid fib lookup for consecutive pkts having same source IP

Type: fix
Fixes: be2286b0

This patch does following:

- If terminating frame has consecutive packets with same source IP, this patch
  avoids fib lookup for those packets in ip4-local node. This drops cycle count
  for ip4-local node on both ARM and x86. It being done by enabling dead code in
  else {} case of ip4_local_check_src_x2() and ip4_local_check_src() functions.

- In case all packets in terminating frame have unique source IP (e.g:
  incrementing), ip4-local is costlier by 2 cycles (broadwell)
