The output of CommentFormatter::addReplyLinks() and consequently
ThreadItem::jsonSerialize() can end up in the HTTP cache (Varnish) on
Wikimedia wikis. We need to consider that when changing that code.
Introduce a concept of legacy ID (generated by the older algorithm
after it changes), add some placeholder code that will generate them
in the future, and update some code to find comments by either normal
or legacy IDs.
Add dire comments in a bunch of places (as if that ever helps).

Previously, parser would output offsets that don't exist in their
containers, because we were pretending that entities are parts of
their neighboring text nodes.
Turns out it's much easier to do it right when going backwards.

When adding a reply, we take a node at the end of the previous comment,
compare that comment's indentation level to the expected indentation level
of the reply, and add (or remove) that number of wrapper lists.
The existing code did not consider that comments may have lists within
them, and so the indentation of that node may not match the indentation
of the comment.
