* This ensures that getText() transforms are completed before
additional output page transformations (and hook handlers) run.
* This change lets us implement DiscussionTools DOM transforms in
a post-parsercache output transform hook. While this hook currently
modifies the ParserOutput object in place (and is considered bad
practice), when the OutputTransform pipeline is instantiated, the
post-cache parser output object is cloned before the pipelines
modify it.
That also opens the possibility of being able to cache the transformed
ParserOutput object separately for scenarios where the transforms
are expensive.
* This is needed by I9846193656cdc658f5237df0a133d9d4dcc20d00 to
make it work as intended.

== Skin::wrapHTML ==
Skin::wrapHTML no longer has to perform any guessing of the
ParserOutput language. Nor does it have to special wiki pages vs
special pages in this regard. Yay, code removal.
== ImagePage ==
On URLs like /wiki/File:Example.jpg, the main output handler is
ImagePage::view. This calls the parent Article::view to handle most of
its output. Article::view obtains the ParserOptions, and then fetches
ParserOutput, and then adds `<div class=mw-parser-output>` and its
metadata to OutputPage.
Before this change, ImagePage::view was creating a wrapper based
on "predicting" what language the ParserOutput will contain. It
couldn't call the new OutputPage::getContentLanguage or some
equivalent as Article::view wouldn't have populated that yet.
This leaky abstraction is fixed by this change as now the `<div>`
from ParserOutput no longer comes with a "please wrap it properly"
contract that Article subclasses couldn't possibly implement correctly
(it coudln't wrap it after the fact because Article::view writes to
OutputPage directly).
RECENT (T310445):
A special case was recently added for file pages about translated SVGs.
For those, we decide which language to use for the "fullMedia" thumb
atop the page. This was recently changed as part of T310445 from a
hardcoded $wgLanguageCode (site content lang) to new problematic
Title::getPageViewLanguage, which tries to guestimate the page
language of the rendered ParserOutput and then gets the preferred
variant for the current user. The motivation for this was to support
language variants but used Title::getPageViewLanguage as a kitchen
sink to achieve that minor side-effect. The only part of this
now-deprecated method that we actually need is
LanguageConverter::getPreferredVariant().
Test plan: Covered by ImagePageTest.
== Skin mainpage-title ==
RECENT (T331095, T298715):
A special case was added to Skin::getTemplateData that powers the
mainpage-title interface message feature. This is empty by default,
but when created via MediaWiki:mainpage-title allows interface admins
to replace the H1 with a custom and localised page heading.
A few months ago, in Ifc9f0a7174, Title::getPageViewLanguage was
applied here to support language variants. Replace with the same
fix as for ImagePage. Revert back to Message::inContentLanguage()
but refactor to inLanguage() via MediaWikiServices::getContentLanguage
so that LanguageConverter::getPreferredVariant can be applied.
== EditPage ==
This was doing similar "predicting" of the ParserOutput language to
create an empty preview placeholder for use by preview.js. Now that
ApiParse (via ParserOutput::getText) returns a usable element without
any secret "you magically know the right class, lang, and dir" contract,
this placeholder is no longer needed.
Test Plan:
* EditPage: Default preview
1. index.php?title=Main_Page&action=edit
2. Show preview
3. Assert <div class="mw-content-ltr mw-parser-output" lang=en dir=ltr>
* EditPage: JS preview
1. Preferences > Editing > Show preview without reload
2. index.php?title=Main_Page&action=edit
3. Show preview
4. Assert <div class="mw-content-ltr mw-parser-output" lang=en dir=ltr>
5. Type something and 'Show preview' again
6. Assert old element gone, new text is shown, and new element
attributes are the same as the above.
== McrUndoAction ==
Same as EditPage basically, but without the JS preview use case.
== DifferenceEngine ==
Test:
1. Open /w/index.php?title=Main_Page&diff=0
(this shows the latest diff, can do manually by viewing
/wiki/Main_Page, click "View history", click "Compare selected revisions")
2. Assert <div class="mw-content-ltr mw-parser-output" lang=en dir=ltr>
3. Open /w/index.php?title=Main_Page&diff=0&action=render
4. Assert <div class="mw-content-ltr mw-parser-output" lang=en dir=ltr>
== Special:ExpandTemplates ==
Test:
1. /wiki/Special:ExpandTemplates
2. Write "Hello".
3. "OK"
4. Assert <div class="mw-content-ltr mw-parser-output" lang=en dir=ltr>

We'll remove ::getTOCHTML() and ::setTOCHTML() shortly as well, but
we need to adjust our parser cache serialization tests first.

It is difficult to distinguish this method from OutputPage::addJsConfigVars()
in code search:
https://codesearch.wmcloud.org/deployed/?q=%5BOo%5Dut%28put%29%3F%28%5C%28%5C%29%29%3F-%3EgetCategories%5C%28&files=&excludeFiles=&repos=
We generally try to replace $output with $parserOutput or $pOutput
as we touch code to improve the ability of codesearch to dig up
deprecated ParserOutput methods.

This has effectively been deprecated since 1.40, since it would
involve a call to ParserOutput::setTOCHTML() which was itself
hard-deprecated in 1.40. But emit a deprecation warning on this
branch just to clarify the downstream messaging further.

Change-Id: I02b40290717e07927a4995de4b06e83a879fc734
The page title is expected to be HTML, albeit "safe" HTML which is stripped
of many tags. FORMAT_PARSE/FORMAT_BLOCK_PARSE and FORMAT_ESCAPED are the
three Message types which emit HTML, and ::escaped() is the most reasonable
(aka fastest) one to use by default for page titles. For callers which
do want literal HTML in the title, they can use Message::rawParams()
or pass the argument as a string.
However, historically ::setPageTitle() has used ::text() to format
Message objects passed as its argument. In my survey, I could not find
any caller which used HTML metacharacters and would be affected by
changing the formatting from TEXT to ESCAPED, but in order to prevent
regressions I've introduced a new method ::setPageTitleMsg() and
soft-deprecated the use of ::setPageTitle() with a Message argument.
Eventually I hope ::setPageTitle() will only take strings and all
callers passing a Message will use ::setPageTitleMsg(), which should
also help out phan-taint-check.

ParserOutput::addOutputHook() has been deprecated since 1.38, and without
any calls to ::addOutputHook() the associated ::getOutputHooks() and
$wgParserOutputHooks configuration do nothing.
