Othercontent would often contain the opening tag of the next heading /
section. By looking for the closest node with a previousSibling we can
more-reliably escape the heading.
Also, only add the initial placeholder if there's content before the
first heading. We do this by testing for any siblings before the
startContainer of the first heading -- if there are any, assume this
means there's some sort of content. (This can still result in a
placeholder with `othercontent:""` if there's only whitespace before
the first heading.)

Rename ThreadItem to ContentThreadItem, then create a new ThreadItem
interface containing only the methods that we'll be able to implement
using only the persistently stored data (no parsing), then create a
DatabaseThreadItem. Do the same for CommentItem and HeadingItem.
ThreadItemSet gets a similar treatment, but it's basically only for
Phan's type checking. (This is sad.)

While in many cases the class will never be sub-classed, it's easier
just to always use static:: and not worry about predicting which
classes might have problems in the future.

Change the order of checks to ensure that we have at least one comment
before we try comparing ranges, to avoid issues with empty headings
having collapsed ranges. It should be a tiny bit faster this way, too.

Phan can analyze them now and reports some issues with types.
* Add some assertions on types where we're sure that we're using an
Element or non-null, but Phan can't prove it
* Fix incorrect type hints on getFullyCoveredSiblings() and
getCoveredSiblings(), luckily it was harmless

`tagName` is only defined on Element, and it returns its tag name.
`nodeName` is defined on Node, and it returns the tag name for Elements,
and a string like '#text' or '#document-fragment' for other types.
We were using both, which made it harder to reason about what types
we're dealing with.

It is friendlier for static analysis tools like Phan, which can't
infer anything from the `->nodeType === …` checks, and we were already
using it in most places.
Fix newly revealed Phan failures (and one unneeded suppression).

Previously, we required a signature at the end of the comment.
This was a pretty rough heuristic that did not correctly handle
many comments that we would consider entirely properly signed
in CommentParser (e.g. comments wrapped in formatting like
<small>…</small>, comments with a post-scriptum or in parentheses,
or comments generated by various templates).
Now we process the user input using the same code that adds reply
links, and only add a signature when we detect that there really
isn't a signature (including template-generated), or if the signature
is in the wrong place and would result in the reply link showing up
in the wrong place as well (not at the end of the comment).

When we encounter a node that doesn't represent comment contents, e.g.:
* a [reply] link we inserted (T297034#7641334)
* an {{outdent}} template (see changed test case)
…we should ignore it together with its descendants (like in
Parser#nextInterestingLeafNode), instead of processing descendants
and possibly detecting comment contents in them.

In PHP, use DOMCompat::getClassList(), provided by Parsoid.
In JS, use `.classList`, available in all supported browsers.
This may fix some bugs where we were incorrectly checking for exactly
one class. The change in isOurGeneratedNode() is needed for

Usually this isn't a problem, because the comments are marked as
template-generated and we don't allow replying to them. But we had a
special case where we were trying to skip over some invisible
elements, which was causing us to skip into the middle of the
about-group in some cases. When Parsoid sees that, it serializes the
contents twice.

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.

Use DOMCompat::querySelectorAll() instead.
CommentModifier::isHtmlSigned()
* Copied the CSS selector from the JS equivalent function.
CommentUtils::unwrapParsoidSections()
* Copied the CSS selector from the JS equivalent function (in VisualEditor).
CommentItem::getMentions()
* Trivial.
This causes Phan to report some more issues, which are also fixed.

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.

In some cases it would return the parent node, instead of the siblings
it should return.
It's a private method only called by getFullyCoveredSiblings(), and
that method had a bug that cancelled out this one, so everything
worked correctly. But I want to use it elsewhere now and ran into it.

I found this error in our logstash. I was not able to find an
existing Phabricator ticket.
Note how line #348 extracts the last element from the
$siblings array. It uses the function end() there, which
returns false in case the array is empty. $siblings[0] can't
do this but yields an error.
An alternative is to use reset(), which can return false as
well. But that's not really better. Especially not better
readable, I would argue.

Add yet another tree walking utility: CommentUtils::linearWalk().
Unlike TreeWalker, it allows handling the beginnings and ends of nodes
separately – kind of like parsing a XML token stream, or kind of like
VisualEditor's linear model.
(Add unit tests for this utility. The simple.html test case is copied
from [VisualEditor/VisualEditor]/demos/ve/pages/simple.html.)
Use this utility to stop skipping when we reach either a closing or
opening block node tag. Previously we'd skip over such tags inside
nested "transparent" nodes (like <a>, <del>, or apparently <font>).
