Fix spurious edits and require incoming edits to be explicitly marked as such (#17918)

* Change post text edit to not be considered significant if it's identical after reformatting

* We don't need to clear previous change information anymore

* Require status edits to be explicit, except for poll tallies

* Fix tests

* Add some tests

* Add poll-related tests

* Add HTML-formatting related tests
