The PHP DOM extension measures lengths and offsets in Unicode codepoints.
Our PHP code used UTF-8 bytes, causing some offsets to be slightly off.
Now it mostly uses Unicode codepoints as well (we're forced to use bytes
in a few places, because preg_match returns offsets in bytes).
In practice, this had no visible effect to the user. It caused the
markers `<span data-mw-comment-end="..."></span>` to be placed at
the end of their container instead of the correct position when the
timestamp contained multibyte characters (e.g. "ź" in Polish); but
the correct position is usually at the end of the container anyway.
In the test cases, the only difference is placing these markers before
a trailing line break inside `<p>...</p>` tags rather than before it.
The patch also accidentally fixes another bug, where element nodes
with no children (mostly <img>) were incorrectly excluded when calling
cloneContents(), because they were treated as if they were text nodes.

If the user talk edit or mention coincides with exactly one new comment:
* Change the primary link to be a direct link to the comment
* Add a text snippet to notifications that don't already include one
(user talk edits that are not new sections).
This is done for all such notifications, regardless of whether anyone
has topic subscriptions enabled.

* ThreadItem::getText
* CommentItem::getBodyText (used when generating notifications)
* ThreadItem::getHTML (may soon be used in API)
* CommentItem::getBodyHTML (may soon be used in API)
* ImmutableRange::cloneContents (the common implementation for all
of the above)
The outputs are only lightly reviewed. This is mostly meant to
document the current behavior rather than the expected behavior,
to avoid making unintentional changes while refactoring.

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.

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.

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).

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).

Disable the legacy htmlPrefilter from jquery.migrate.js, which is
causing noisy warnings when running tests because we use HTML
templates with wacky content in the test module. They look like this:
"JQMIGRATE: HTML tags must be properly nested and closed: <200 KB of HTML>"

The issue occurred when replying to a comment consisting of multiple
list items, starting with a <dt> (instead of the expected <dd>), so
that the comment is considered to be unindented.
Modifier tried to add the reply directly inside the list (<dl>) rather
than inside the last list item (<dt>), which caused it to be confused
about indentation levels and try to un-indent more times than there
were indentations.
The simplest solution, given the existing code, is to add the reply
outside the list instead, in a new list. This results in a "list gap"
(<dl><dt>...</dt><dd>...</dd></dl><dl><dd>...</dd></dl>), but I think
it's acceptable for this rare case.
There are separate tests cases for old Parser and for Parsoid HTML,
because they parse the original wikitext differently (with the old
Parser producing HTML with a list gap too).

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.

The existing comment IDs can't be used to find the same comment on
a different revision or page (when it's transcluded), because they
depend on the comment's parent and its position on the page.
Comment names depend only on the author and timestamp. The trade-off
is that they can't distinguish comments posted within the same minute,
or in the same edit, so we will still need the IDs sometimes.
Prefer using comment names when replying, if they're not ambiguous.
This fixes T273413 and T275821.
Heading names depend on the author and timestamp of the oldest comment.
This way we don't have to detect changes to the heading text, but we
can't distinguish headings without any comments.

The code we're testing already produces a string of serialized HTML,
no need to parse and re-serialize it.
Also, we recently learned that the precise format matters here
(T274709), and now this test *actually* covers the fix for that bug.
Follow-up to 5b26e9664b.
As a downside, this test might now spuriously fail if the format of
the output of Parsoid's XMLSerializer changes. Hopefully that won't
happen too often.
