Notifications are bundled by section, so instead of linking to the
comment, link to the section.
Additionally, add a parameter to the URL listing all the comment IDs
from the bundle, and highlight them all and scroll to the topmost one.
Having to handle both URL fragments and URL query parameters makes
this code kind of a mess :(
Also, some unexpected changes became necessary:
* EventDispatcher.php: Store the section title in events using
HeadingItem::getLinkableTitle() instead of ThreadItem::getText().
The result is mostly the same, except in case of wacky markup like
images or extension tags. We can more reliably use it to link to the
section on the page, and we already use getLinkableTitle() when
generating edit summaries in the reply tool for this reason.
* dt.init.less: Change the mix-blend-mode for the highlights from
'multiply' to 'darken', so that multiple overlapping highlights do
not look more opaque. This affects how the highlights look on
non-white backgrounds and images (they're less blue, and on darker
backgrounds entirely invisible), but it seems worth it.

The code (prior to d25825a754) assumed
that level 3+ headings would always follow a level 2 heading or the
placeholder heading, but we don't generate a placeholder heading if
there are no comments in section zero.
Add more tests to confirm that comments under level 3+ headings (that
are not sub-headings of level 2), and level 1 headings, are ignored
when generating notifications, and do not mess with normal headings.

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.

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

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.

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).

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.
