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.

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).

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.

If the revision from which we generated the notification has been
deleted, we shouldn't include the content snippet, nor the direct link
to the comment (because the fragment ID is generated from the content).
This matches how Echo handles mention notifications.
Change-Id: Ica939f3a4efd39d0c295511d58280d3f9d584129
As it happens, most of Echo does not actually parse this message,
but it is for some reason parsed in HTML email notifications.

We don't display [subscribe] buttons on your user talk page,
but the API still allows those subscriptions.
Use the same approach as for mentions to ensure this doesn't cause
duplicate notifications.
Remove some code in SubscribedNewCommentPresentationModel,
now guaranteed to be unused.

Otherwise, the global context is used (RequestContext::getMain()),
which is undesirable when you're building a rubegoldbergian
contraption and we're already inside an internal action API request
with a fake context.

Per Manuel Arostegui in T263817#7033384. The limit is 5000.
(I picked it arbitrarily, there's no real rationale for it.)
Also log a warning when any user reaches half of the limit,
so that we might make a decision about changing this mechanism
before it starts affecting users. Maybe at that time we'll
have data to show that it's safe to remove the limit.

Using `updateCacheExpiry()` in this way appears to be established
with examples of other use in WMF production such as:
- CategortyTree extension:
custom cache expiry for pages with `<categorytree>`.
- RSS extension:
custom cache expiry for pages with `<rss>`.
- intersection extension:
custom cache expiry for pages with `<DynamicPageList>`.
- Math extension:
custom cache expiry if `<math>` failed.
- Wikibase extension, Flow extension:
no caching for certain namespaces or content types.
- Graph extension, Kartographer extension:
via onParserAfterParse hook, no caching if on preview.

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).

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).
