First havana commit.

First havana commit.

This commit indicates that the master branch has moved on to
representing the "havana" release.  The previous commit will be use to
start the milestone-proposed branch for grizzly.

All future changes for grizzly must first be merged
into master, and then back-ported to a grizzly milestone-proposed branch
(or once grizzly is released, the stable/grizzly branch).
