Bartosz Dziewoński af68c835bb Update exception handling for new code conventions
Change code to match the documented consensus formed on T321683:
https://www.mediawiki.org/wiki/Manual:Coding_conventions/PHP#Exception_handling

* Do not directly throw Exception, Error or MWException
* Document checked exceptions with @throws
* Do not document unchecked exceptions

For this extension, I think it makes sense to consider DOMException an
unchecked exception too (in addition to the usual LogicException and
RuntimeException).

Bartosz Dziewoński 3a9997d6ea Improve handling for comment separators
* Detect comment separators at the end of comments too
* Consider TemplateStyles associated with ignored templates

This unexpectedly improves a lot of cases other than T313097 too,
mostly where <br> or {{outdent}} was used within a paragraph:
splitting comments that were previously jumbled together, or restoring
content that was previously ignored for apps / notifications.

Bartosz Dziewoński cfa45a5f4c Remove all stuff about legacy IDs
We can no longer change IDs so easily, because they're stored in the
permalink database, so remove this mechanism to make sure it's not
accidentally used in the future.

Bartosz Dziewoński 880f9755e0 Separate ContentThreadItem and DatabaseThreadItem etc.
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.)

Ed Sanders af54bae2ec Prefer late static binding over self::
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.

Bartosz Dziewoński 584f6a020c Use tagName rather than nodeName when we know the node is an element
`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.

using it in most places.

Bartosz Dziewoński 8e44b43df0 Split off ThreadItemSet from CommentParser
Goal:
-----
Finishing the work from Iadb7757debe000025e52770ca51ebcf24ca8ee66
by changing CommentParser::parse() to return a data object, instead of
the whole parser.

Changes:
--------
ThreadItemSet.php:
ThreadItemSet.js:
* New data class to access the results of parsing a discussion. Most
  methods and properties are moved from CommentParser with no changes.

CommentParser.php:
Parser.js:
* parse() returns a new ThreadItemSet.
* Remove methods moved to ThreadItemSet.
* Placeholder headings are generated slightly differently, as we process
  things in a different order.
* Grouping threads and computing IDs/names is no longer lazy. We always
  needed IDs/names anyway.
* computeId() explicitly uses a ThreadItemSet to check the existing IDs
  when de-duplicating.

controller.js:
* Move the code for turning some nodes annotated by CommentFormatter
  into a ThreadItemSet (previously a Parser) from controller#init to
  ThreadItemSet.static.newFromAnnotatedNodes, and rewrite it to handle
  assigning parents/replies and recalculating legacy IDs more nicely.
* mw.dt.pageThreads is now a ThreadItemSet.

Bartosz Dziewoński 4613ae78e7 Change CommentParser into a service
Goal:
-----
To have a method like CommentParser::parse(), which just takes a node
to parse and a title and returns plain data, so that we don't need to
keep track of the config to construct a CommentParser object (the
required config like content language is provided by services) and
we don't need to keep that object around after parsing.

Changes:
--------
CommentParser.php:
* …is now a service. Constructor only takes services as arguments.
  The node and title are passed to a new parse() method.
* parse() should return plain data, but I split this part to a separate
  patch for ease of review: I49bfe019aa460651447fd383f73eafa9d7180a92.
* CommentParser still cheats and accesses global state in a few places,
  e.g. calling Title::makeTitleSafe or CommentUtils::getTitleFromUrl,
  so we can't turn its tests into true unit tests. This work is left
  for future commits.

LanguageData.php:
* …is now a service, instead of a static class.

Parser.js:
* …is not a real service, but it's changed to behave in a similar way.
  Constructor takes only the required config as argument,
  and node and title are instead passed to a new parse() method.

CommentParserTest.php:
parser.test.js:
* Can be simplified, now that we don't need a useless node and title
  to test internal methods that don't use them.

testUtils.js:
* Can be simplified, now that we don't need to override internal
  ResourceLoader stuff just to change the parser config.

  analysis. This generates all kinds of confusing warnings.

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.

C. Scott Ananian 25272e7a4a Don't refer directly to PHP dom extension classes; avoid nonstandard behavior
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.

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.
