Patch to upgrade

This release has a couple of new features and a list of bug fixes.
trustanchor.unbound chaos query, response IP actions, stats from
shm, --disable-sha1, dnscrypt support, and edns client subnet support
merged in.

Best regards, Wouter

Features
- Add trustanchor.unbound CH TXT that gets a response with a number
  of TXT RRs with a string like "example.com. 2345 1234" with
  the trust anchors and their keytags.
