relnotes: various tweaks for release notes
Stop filtering out commits that are expected to be covered by releasenotes
extension: now we want two lists, one for WhatsNew and one for ReleaseX.Y.
Use `only(stoprev, startrev)` to make `relnotes -h` output be actually true
about what revisions are included.
More filter rules, mostly obvious.
More classifying rules to have less things in "unsorted".
Looks like nargs=1 was just making args.startrev and args.stoprev be lists for
no reason.
BC and API sections are renamed to what we're using on the WhatsNew page, and
also just skipped if empty.

a reduced version of code in the Munki tool used by some large
organizations to centrally manage OS X packages, which is what
inspired this kludge.
