Add asserting verifying that a QCoreApplication exists when

makes invalid use much more visible. Without the assertion
only a message about invalid nullptr used with QObject::connect()

QEventDispatcherGlib: it used the out-parameter timespec to set a
timeout in milliseconds, making timerWait() return milliseconds is more
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.

Those are "public-ish" and exported functions (qstringalgorithms.h), so
one wouldn't expect that they get inlined most of the time. But they can

with LTO.
More importantly, we want the compiler to inline qustrXXX_avx2() into

no-op but has one very important difference: backtraces will point to an
exported, function instead of an internal symbol. This will then allow

These classes are not exported, so we don't run into duplicate vtables
here, but the header is included in a few TUs other than qhostinfo.cpp
(all, when building with PCH), so make sure we compile dtors only once.

Upstream change: https://github.com/intel/tinycbor/pull/238
Says it in the upstream commit message:
> Unfortunately, the container's initialization code doesn't exactly
> lend itself to making the container const (not even IILE
> (Immediately-Invoked Lambda Expression) would help here, due to the
> interdependency with len), so the idiomatic solution would be to use
> std::as_const()/qAsConst().

> The former is available from C++17, which we don't require, yet, and
> the latter is not available under QT_NO_AS_CONST (the default for Qt

> switches between a manual implementation of std::as_const and the
> real thing, depending on __cpp_lib_as_const. The t17 here mimicks

QPaintDeviceWindowPrivate::markWindowAsDirty() is used to signal that
the entire window needs repaint, for example when the window is being
resized. If multiple resize events come in before we have a chance to
redraw the window, we'll end up redrawing the window based on the
window's current size and exposed region, as we should, but we'll
still have a dirty region, because we didn't redraw the window at
any of its old (larger) sizes. Resetting the dirty region instead
of appending to it should be enough.
