  NSH: Adjust NSH wire format to the latest IETF draft

This commit adjusts the NSH user space implementation in OVS to
the latest wire format defined in draft-ietf-sfc-nsh-28 (November 3
2017). The NSH_MDTYPE field was reduced from 8 to 4 bits. The FLAGS
field is reduced from 8 to 2 bits. A new 6 bit TTL header field is
added. The TTL field is set to 63 at encap(nsh).

Match and set_field support for the newly introduced TTL header field
and a corresponding dec_nsh_ttl action is not yet included and will be
implemented in a future patch.
