Merge remote-tracking branch 'remotes/dgilbert/tags/pull-hmp-20170221' into staging

HMP pull

Note, I had seen a fail in the vhost-user/flags-mismatch on one
host in one build, but not others with the same patches; and these patches
go nowhere near that, so I think that's a separate vhost-user issue.
