The PHP `global` statement actually creates a global variable if it
does not exist yet, setting it to null. Who'd have thunk.
This is reported as a new issue type 'MediaWikiNoIssetIfDefined' by
mediawiki/mediawiki-phan-config to 0.15.0.

Follow-up to 3d9585acbe.
* Avoid deprecated method StatusValue::getErrors()
* Don't use exceptions for control flow
* Don't re-use Parsoid's ResourceLimitExceededException,
it seems unexpected to me and might limit future refactoring
* Use dieStatus() instead of dieWithException(), which will produce
better localised error messages
* Add missing error handling in ApiDiscussionToolsThank

I tried to benchmark this. It's not really a big bottleneck in this
codebase, but can still be seen. For example, the relative runtime
of the method CommentUtils::isCommentSeparator (the heaviest user of
this feature) goes down from 1.5% to 0.3%.

Instead of checking section->exists() everywhere we have to call
getTruncatedSectionTitle(), override the method inside
PlaintextEchoPresentationModelSection class to make it always
return string for our case.
Call to getTruncatedSectionTitle() in the following classes now use
the method override:
* RemovedTopicPresentationModel
* SubscribedNewCommentPresentationModel
* AddedTopicPresentationModel
The call to getTruncatedSectionTitle() in CommentThanksPresentationModel
does not need nor use the override.

If the subject page/user doesn't exist it usually makes sense
not to show the "Start a discussion about X" message, but when
the talk page itself exists but without any discussions
(e.g. after a Flow archiving), then we _should_ show message to
start a new discussion.

EchoPresentationModelSection::getTruncatedSectionTitle() has a note that
it should not be called if ::exists() returned false. Among the reason
the section may not exist includes suppressing the revision where the
topic title was added or edited.
Add placeholder message text "(topic removed)", to be used in place of
the unavailable topic title. This is analogous to "(user removed)" which
would be shown along if the username is also suppressed.

Implicitly marking parameter $... as nullable is deprecated in PHP
8.4. The explicit nullable type must be used instead.

For interface messages, like the talk page header, tranformHtml isn't
run so no value is set while parsing it. The double negative in
I5c1877f7f9eb73f88a33e001ca3c2f3d06bb90e4 failed to account for that and
was reverted in I23a3f937201d93c7c7645a09c4fccfcf1c14008a.
By always setting a value, we'll overwrite a value that may have been
set when Parsoid calls the legacy parser to parse extension content for
which it doesn't have a native extension, which then gets merged into
the metadata for the main parse. However, setting with a different
value is deprecated and will eventually throw, but we already need to
find a solution for T372592 so what's one more.

Some extraSignaturesNamespaces often have pages which are never
used as talk pages. This check will suppress "topic not found"
messages from appearing on those pages.

Silence the deprecation warning instead to avoid regressing T372193.
I filed T372592 about the bigger problem we have here.

Record if a talk page is not empty, rather than empty.
This helps prevent Parsoid from mislabelling pages as empty when they
contain extension tags it needs to call out to the legacy parser to
process. Metadata from the legacy parse is merged into the overall
metadata for the page.
For example, a templatestyles extension tag parsed in the context of a
talk page would set the empty state which would then fail to cleared if
the overall parse of the page wasn't empty.
Bartosz (@matmarex) proposed this idea in T371125#10053043
Setting and using these flags all appear to be post-retrieval from
cache.

While investigating primary database queries as part of T370304,
we found that EventDispatcher currently issues a primary DB query
to fetch the previous revision of the newly created revision on
every edit, but discards the result for non-talk pages. So, as an
optimization, have it fetch the previous revision only after the page
has been established to be a talk page.

The previous approach no longer works due to changes in MediaWiki.
We must now pass the data between the hook which has access to request
state needed to determine if we should show this, and the hook that is
capable of showing it in the right place.
