Bartosz Dziewoński c1f4668806 Change CommentParser and ImmutableRange to use offsets in codepoints instead of bytes
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.

Bartosz Dziewoński a6a547f2b2 Add some tests covering ThreadItem::getHTML() and related methods
* 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.

Bartosz Dziewoński a3f665e816 Remove <header> tags around headings for compat with MobileFrontend
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.

Bartosz Dziewoński 42ce942c86 Introduce comment "names" to identify comments across revisions/pages
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.

Bartosz Dziewoński 5a07139249 CommentFormatterTest: Avoid re-serializing the HTML
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.

Bartosz Dziewoński 0fc71f60cd Skip to the end of the paragraph if it's just text, too
We've recently decided that we want to "extend" comments until
the end of the paragraph (e36dc8e78a,
d0ae6c4e44).

However, we still had this special case that did the opposite: it
ensured that if a comment ended in the middle of a text node, the
comment would not be extended to the end of the node. Remove it.

Note the change in the test file signatures-funny-formattedreply.html,
which actually covered this case specifically.

Ed Sanders d0ae6c4e44 Skip end marker "forward" until a block tag is reached
The end marker is skipped forward until an open or close
block tag is reached. In tree traversal terms this means
moving either to the next sibling, or the parent (to skip
over close tags).

heading ID.

Bartosz Dziewoński b09bbfe668 Disambiguate comments by parent ID, rather than sequential numbers
Sequential numbers aren't great because they change when an earlier
comment is archived. Parent comment/heading IDs should change less
often.

This also makes much more sense for disambiguating subsections,
e.g. a dozen identical ===Votes=== sections for a dozen proposals.

Bartosz Dziewoński e36dc8e78a Skip to the end of the paragraph in the parser, not modifier
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.

Bartosz Dziewoński ccd9e411d2 Allow updating the expected results when running PHP tests
This is similar to the code we already have in JS tests, but instead
of printing to the console where you have to copy-paste from, it just
overwrites the files.

Also, update all of the expected results by this method.

Changes in the expected outputs:
* In JSON files, the "warnings" are now always in the same place
  regardless of the type of the warning.
* In all HTML files, self-closing tags now include the trailing slash,
  some characters are no longer encoded as entities when not necessary,
  and attributes may be single-quoted when that makes them shorter.
* In Parsoid HTML files, the header is no longer terribly mangled.

Other notes:
* CommentParserTest.php: Change the output of serializeComments()
  to be in similar order as in JS, to reduce the diffs in this commit
  and because it's a better order for humans.
* modifier.test.js: Remove some hacks that were working around small
  inconsistencies between the previous expected outputs and the actual
  outputs.
