Merging release branch

[Glenn Morris]

I've had enough of merging the release branch to master,
so someone else will have to do it from now on.

I use admin/automerge from cron with a wrapper that:
1) first checks the release branch passed make check
2) passes "-n 1" if the last merge was more than 1 week ago

The final straw was a triple failure in the automatic merge today due to:
an easily avoidable build breakage in the release branch
a non-repeatable check failure due to network-stream-tests timing out
  (such classes of test failure are common)
3 separate merge conflicts due to the same code being modified on both branches
