This will need adding to the release notes.

@MaskRay: what's your opinion on whether this should be enabled by default? Enabling by default means that those who are accidentally creating invalid notes will be warned about it. On the other hand we'll break people's build, if they are deliberately creating invalid ones (I don't know why you would outside of testing). My inclination is on by default, since there's an easy way to get out of the situation with the new `--no-verify-note-sections` option.
