contrib: import the relnotes script from the release-tools repo
I figure this makes more sense to keep in the main repo, as it's a
guide of sorts on how to use the releasenotes extension in the
presence of commits that don't get relnotes annotations.
Ported to Python 3, cleaned up some logic in a few places, but for the
most part it's what we've been using for years.

hghave: move from requiring the PYTHON3 env var to looking for `python3`
We're starting to write new utility scripts in Python 3, and I think
it's reasonable to expect `python3` to be something we should use if
it's present. I wrote the regex to specifically ban Python 3 prior to
Python 3.5 because we won't ever support that.
I moved the only test that was using $PYTHON3 to just using `python3`
directly.

rename: return error status if any rename/copy failed
Ever since
447ea621e50e (copy: propagate errors properly, 2007-12-06),
we have returned an error status if the source file did not
exist. That commit did not return error status for any other errors,
and it's unclear if that was on purpose or not. It seems to me like we
should return an error in the other cases to, so that's what this
patch does.

rename: emit hint about using --after consistently
Both the code and the message for the case where the source file was
missing was inconsistent with the other similar messages.

rename: quote hg commands in warnings
I think we usally use single quotes around hg commands in messages.

zsh_completion: adjust usage of common options
addremove, remove and serve accept -S/--subrepos, and purge actually doesn't.
qnew accepts -I/--include and -X/--exclude.
qrefresh accepts -D/--currentdate, -U/--currentuser, -d/--date and -u/--user.
rebase accepts -n/--dry-run.
