Comment boundaries are stored as a DOM parent node plus a child index.
Because of that, inserting anything into the DOM before a comment –
such as another comment's start/end markers – would cause us to insert
subsequent comments' markers into the wrong places.
This issue didn't affect many pages, because usually any parent node
would have just one comment in it. Only pages with comment boundaries
outside of any wrappers (directly inside the root node) were broken.
Just process the list in reverse to fix this.

When our interface initialized on a page that the current user
recently edited (using the reply tool, the full-page source editor,
or any other way), check if any new automatic topic subscriptions
were added and update the interface to reflect that.
This requires doing some API requests after the page is loaded,
because adding auto-subscriptions happens asynchronously in a
DeferredUpdate (potentially after the user is already viewing
the page with their comment saved), and depends on the contents
of the edit.
(When using the reply tool, we could avoid this API request and
replicate the logic, but that's not implemented in this commit
to keep it simple.)

This should avoid them showing up in unexpected contexts where parser
output is used (e.g. API T292345, search T294168, action=render).
Also rename some variables to be directionality-neutral.

We always do our processing in the parser now, so we don't need the
marker comment to detect whether we've already processed the page.
Bonus: include the time taken by our processing in the limit report.

This DOMDocument property has no effect, because we do not use
DOMDocument methods for parsing HTML, but rather DOMUtils::parseHTML()
provided by Parsoid.

Use `DOMCompat::getBody( ... )` as a nicer getter than
`->getElementsByTagName( 'body' )->item( 0 )`.
Remove overly defensive checks and redundant annotations on its
return value. Since we're dealing with HTML documents throughout,
the document body is guaranteed to exist.
We previously needed some of them to convince Phan when it thought
the body may be null, but this seems to no longer be needed.

These changes ensure that DiscussionTools is independent of DOM
library choice, and will not break if/when Parsoid switches to an
alternate (more standards-compliant) DOM library.
We run `phan` against the Dodo standards-compliant DOM library,
so this ends up flagging uses of non-standard PHP extensions to
the DOM. These will be suppressed for now with a "Nonstandard DOM"
comment that can be grepped for, since they will eventually
will need to be rewritten or worked around.
Most frequent issues:
* Node::nodeValue and Node::textContent and Element::getAttribute()
can return null in a spec-compliant implementation. Add `?? ''` to
make spec-compliant results consistent w/ what PHP returns.
* DOMXPath doesn't accept anything except DOMDocument. These uses
should be replaced with DOMCompat::querySelectorAll() or similar
(which end up using DOMXPath under the covers for DOMDocument any way,
but are implemented more efficiently in a spec-compliant
implementation).
* A couple of times we have code like:
`while ($node->firstChild!==null) { $node = $node->firstChild; }`
and phan's analysis isn't strong enough to determine that $node is still
non-null after the while. This same issue should appear with DOMDocument
but phan doesn't complain for some reason.
One apparently legit issue:
* Node::insertBefore() is once called in a funny way which leans on
the fact that the second option is optional in PHP. This seems to be
a workaround for an ancient PHP bug, and can probably be safely
removed.

Change-Id: I3c4f41c3819770f85d68157c9f690d650b7266a3
For compatibility with Parsoid's document abstraction (Parsoid may
switch to an alternate DOM library in the future), don't explicitly
create a new document object using `new DOMDocument`; instead use
the Parsoid wrapper `DOMCompat::newDocument()`. This ensures that
the Document object created will be compatible with Parsoid.
There are a number of other subtle dependencies on the PHP `dom`
extension in DiscussionTools, like explicit `instanceof` tests; those
will be tweaked in a follow-up patch
(I3c4f41c3819770f85d68157c9f690d650b7266a3) since they do not affect
correctness so long as Parsoid is aliasing Document to a subclass of
the built-in DOMDocument. Similarly, the Phan warnings we suppress
do not cause runtime errors (because of the fixes included in
c5265341afd9efde6b54ba56dc009aab88eff83c) but phan will be happier
once the follow-up patch lands and aligns all the DOM types.

The regexps needs to be non-greedy, otherwise it could swallow up a
large chunk of the page (up to the next comment).
I noticed this when adding tests for this code, in the 'unclosed-font'
test case (Ief9648b8805fadcc170c54b627eb669cc8b907b6).

We added it because the initial designs for the subscribe action were
much easier to implement like this, and topic "containers" (T269950)
would have required it.
However, the latest design of the subscribe action will not need it
(T279149), and topic containers are still very far away, so let's
remove it for now.

Longer, but follows the style guide and less likely to conflict.
We need to account for init classes in the cache being around for
a while.

This code expected $container->firstChild to be a
<div class="mw-parser-output">, but that element is not present
when we're running on HTML to be saved in parser cache.
We ended up inserting the marker inside whatever node was the
first on the page, and if it was a <style> element, both our
marker and the styles would be lost when serializing, like in
6c7a0ca9a2.
When we're running on final HTML, the marker will now be outside
of <div class="mw-parser-output">, but that seems to be fine. Only
early versions of I4e60fdbc098c1a74757d6e60fec6bcf8e5db37c1 had
problems with that (see comments on patchset 41), but it works now.
The added test case also covers the fix for T274709.

Going forward this will allow us to remove the parser
cache split, and toggle features just using CSS.
The CSS will be modified in a later commit to give the
anon caches time to clear.

As CommentFormatter no longer needs HTMLFormatter, remove
the inheritance and make addReplyLinks a static method.
Testing locally this is marginally slower, going from 2.55s

for replying. But we might also use them for notifications soon.

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).
