This series adapts the userspace implementation for NSH in OVS to the wire-format specified in the latest NSH IETF draft and fixes a few minor bugs in the implementation.

The corrections are minimal and primarily meant to be backported to branch-2.8. The NSH userspace support on master will be refactored substantially as soon as the ongoing implementation of NSH support in the Linux kernel datapath is completed.
Then we will also provide the outstanding match field support for the new TTL field and a dec_nsh_ttl action.

I have also tested this patch series on branch-2.8. They apply cleanly and NSH tests pass.
