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 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.

After recent changes allowing ThreadItems to have IDs, they can now
also have warnings about duplicate IDs.

Ed Sanders 3aca622894 Treat headings like comments now they have IDs
Use the same logic for marking ranges in the document, and ensure
that the heading range does not include section edit links or
section numberings.

Bartosz Dziewoński 044bc50fb6 Fix some TODOs about test data
We avoided fixing these because it causes changes in just about all of
the test data, which is annoying when reviewing or blaming changes.

But the previous several commits also caused changes in just about all
of the test data, so we might as well do this too.

Bartosz Dziewoński 0ddc171c8a Add oldest timestamp in the thread to heading IDs
To avoid old threads re-appearing on popular pages when someone
uses a vague title (e.g. dozens of threads titled "question" on
[[Wikipedia:Help desk]]: https://w.wiki/fbN), include the oldest
timestamp in the thread (i.e. date the thread was started) in the
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 3137d76f40 Connect sub-threads to their parent threads
Our threads now also contain all replies to their sub-threads.
This is similar to how sections work in MediaWiki, where the parent
section also contains the content of all the lower-level sections.
We're going to need this for notifications about replies in a thread.

Bartosz Dziewoński 9ee0fd69f5 Allow headings to have IDs
Previously, only comments could have IDs, because we only needed IDs
for replying. But we might also use them for notifications soon.

Bartosz Dziewoński 432a959436 Ignore empty paragraphs at the beginning of comments
The wikitext parser outputs `<p><br></p>` for empty paragraphs, so we
need to ignore `<br>` tags when searching for an "interesting" node
that marks the beginning of a comment. Otherwise the empty paragraphs
mess up the detection of indentation levels.

which previously wasn't being tested, leading to T261706.
