We can just use insertBefore() normally. There was never a PHP bug,
but rather a Phan bug, and it no longer affects us.

This reveals a bug in CommentParser where it sometimes produces
incorrect ranges (we were incorrectly treating `false` like `null`,
hiding the issue). I'll fix it in a separate commit.
Follow-up to 25272e7a4a.

Adding test cases in a separate commit to make it easier to review how
the test results change after I98fbca8e.
* For mentions, the 'mentioned-users' extra parameter is copied to our
event (which is then used to avoid duplicate notifications).
* For user talk page edit, nothing special happens right now (we use
the target page title to avoid duplicate notifications, but this is
not apparent from the test case, since page titles are not present).

In case 4 and case 6, no notifications are expected. In all other
cases we now get the expected notifications.

Adding test cases in a separate commit to make it easier to review how
the test results change.
As expected, in every case, no notifications are generated right now.

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.

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 user interface only allows you to subscribe to level 2 headings.
But we would generate events for whatever heading was the closest,
If it was e.g. level 3, no one would receive that notification.
Now we generate events for the closest level 2 heading, or we don't
generate the event at all if there isn't one (if the only headings are
of level 3 and below, or level 1, or if the comment is added before
the first heading on the page).

This is the same method as used by VisualEditor
(ve.init.mw.DesktopArticleTarget.prototype.replacePageContent).

We used an internal API requests to fetch page content because it was
easy, but there's no way to guarantee that it returns data from the
primary database.
Use ParserOutputAccess::getParserOutput() to fetch from cache if
available. Also, use canonical output instead of user-specific,
not that it should matter.

* Move getTitleFromUrl() from parser to utils. It's a generic method,
the PHP equivalent is already in utils.

I noticed that the NWE new section editor would open sometimes even
though we attempt to prevent it. This way seems to work more reliably.

Problems with the current setup:
* Each CommentController must have exactly one link.
For T277371 we want multiple, and for T282205 we might want zero.
* CommentController objects must be constructed immediately.
They are implemented to make this pretty fast, but it's still
unnecessary work to do on page load.
* Only one link may be activated at a time, and activating one affects
the styling of others, so CommentController has to use global state
to check if it can set up and to update them.
Instead introduce ReplyLinksController, which knows about all reply
links and which one is active, and emits events that allow
CommentControllers to be constructed on demand.
