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.

* Ignore rendering-transparent nodes between discussion comments.
* Improve isRenderingTransparentNode() so that <link> nodes
representing TemplateStyles are not considered transparent,
otherwise this would undo ae920b831f.

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>).

As a result of 0fc71f60cd, "empty" text
nodes (containing only whitespace) at the end of the comment may be
inside the comment's range, and trying to ignore them caused the
ranges not to match and the frame not to be detected.
Now the code works whether they're inside the comment's range or not.
Add a test case for wrapped discussion comments with HTML comments and
with whitespace.

Move the code so that we check for "?title=" query parameter first,
because we don't handle this right in the other code path.
Use parse_url() instead of wfParseUrl() because the latter doesn't
accept relative URLs, and we don't care about the other differences.

When a comment ended before the end of a paragraph, the next
comment would begin right there in the middle of the paragraph.
This could result in the detected indentation level of that
comment being incorrect, and replies being inserted in wrong
places, as seen in the 'signatures-funny' test case.
The code moved to the parser was previously repeated twice in
addListItem() and addReplyLink(), which should have been a hint
that something isn't quite right.
Also, fix the code guarding against overlapping signatures,
now that signatures may not be at the end of a comment.

When adding a reply, we take a node at the end of the previous comment,
compare that comment's indentation level to the expected indentation level
of the reply, and add (or remove) that number of wrapper lists.
The existing code did not consider that comments may have lists within
them, and so the indentation of that node may not match the indentation
of the comment.
