v3->v4
  - Add new action dec_nsh_ttl
  - Remove encap_nsh and decap_nsh changes
  - Remove netlink rework to adapt to OVS 2.8
  - Dynamically allocate struct ovs_action_encap_nsh and put
    appropriate size for ENCAP_NSH netlink message.

v2->v3
  - Fix several comments Jan Scheurich

v1->v2
  - Rework per kernel datapath review comments
  - Add new NSH key ttl
  - Add many helpers in nsh.h and replace much code
    with these helpers
  - nsh.h includes the lasted NSH spec
  - bits of flags and mdtype have a change

This patch adds new NSH key 'ttl' and a new action
dec_nsh_ttl to follow the lasted IETF NSH draft:

https://datatracker.ietf.org/doc/draft-ietf-sfc-nsh/

I have double confirmed from one of its authors, this
is a final version which will be approved as IETF RFC,
the NSH header format won't be change anymore.

  nsh: fix an implicit bug in nsh_hdr_len
