Add asserting verifying that a QCoreApplication exists when
the application static variable is dereferenced. This is a
requirement described in the documentation. Added assertion
makes invalid use much more visible. Without the assertion
only a message about invalid nullptr used with QObject::connect()
is emitted. This message is much less informative and does
not cause tests to fail.

straightforward. Also timerWait() returns the time rounded to
milliseconds, so the code in QEventDispatcherGlib that rounded up the

operator=(~) and assign(~) share similar names but, until now, have not
shared the same functionality. This patch introduces the usage of
QByteArray::assign() within the non-sharing assignment operator to
effectively boost efficiency by reusing the available capacity.
Since these assignment operators are frequently used in many places,
both within Qt and non-Qt code, this patch comes with benchmarks.
The preview of the benchmark results are compared with this patch and
before this patch. The findings indicate a slight enhancement in
performance associated with the assignment operator. Despite the results
displaying only a minor improvement, progress has been made. Therefore
use assign(QByteArrayView) as replacement.

The MIME database appears to use underscore to join its locale tags,
where QLocale::uiLanguages() uses dashes. This meant that lookups by
anything but the raw language were failing even when there was an
entry in the MIME database for the desired locale. Also, since 6.5,
the uiLanguages() list always does contain the locale's own name, so
don't add it to the list again.
At the same time, the search was putting the "default" key (used by
the MIME database parser for the entry with no locale specified) at
the end of the list but macOS (at least) uses that for the "en_US"
version, omitting "en_US" itself from the locale-specific data, with
the result that those using en_US as locale, but with some other
languages later in the list, got the translation for one of those
languages instead of the en_US one, since they were found before
"default" was reached. So insert "default" after the first block of
en-entries in which en_US appears, if it does, rather than at the end.
As a drive-by, amend a comment about using "pt" as fall-back for
"pt_BR"; as it happens, for pt_BR, uiLanguages() will contain "pt" in
any case, as pt_BR is the default for "pt". (Like en, pt anomalously
defaults to a territory other than the one the language is named
after.) So use de_CH -> de as example, instead (and place the comment
where the decision is taken).

ElideNone was originally introduced as a way of modifying behavior
of specific widgets, such as QTabBar. The text would previously
always be a elided and an ellipsis character would be added somewhere
to indicate this to the user. Given that context, it makes sense
that the documentation says the effect of ElideNone is that ellipsis
does not appear in the text, since the text would still be elided
if it were too long, given that the painter would draw it clipped to
the widget.
When QFontMetrics::elidedText() was introduced later, this became more
confusing. In the context of this function, you would expect the text
to be returned truncated to the width but without the ellipsis character.
Instead it just returns the full string.
Since this has been the effect of ElideNone since the start and multiple
places use it as a way of disabling the truncation of the string, we
simply update the documentation to make this more clear.
