QSlotObjectBase, which can handle free functions, member functions,

According to the Freedesktop spec[1], a mimetype that has glob-deleteall
overwrites other glob-pattern definitions for a mimetype if it is in a
higher precedence dir, the default order is (from high to low)
~/.local/share/mime, /usr/local/share/mime, /usr/share/mime. Or if the
XDG_DATA_DIRS env var is set, then it takes precedence. The
QMime*ProviderS in m_providers are constructed/stored in that same

For QMimeXMLProvider, we can just clear the glob patterns associated

however, we can't change the binary (mmap'ed) cache file, instead check

Add helper that allows us to determine the argument list and return type

operator()() overloads (we only support zero-argument call operators, but
there might be const/noexcept variations). Use that helper to declare a
ZeroArgFunctor type which also declares a ReturnType and Arguments alias.

It seems glibc's extrapolation of existing DST-rules cuts off at some
point in the distant future, where the IANA DB gives no end-time for
such rules, leading QTimeZone to keep applying them. This lead to
tst_QDateTime::fromSecsSinceEpoch() not getting an invalid date in one
of its bounds-probing tests, due to a within-bounds datetime getting
glibc's offset and then the out-of-bounds one falling back to the IANA
rule's offset that put it back within the bounds.
This directly affected Australasian zones (which glibc locks into
daylight-saving time in this distant future) which were fixed by using
the IANA DB's offset; but the relevant date is in August so other
zones, north of the equator, that glibc locks into standard time, then
had the reverse problem, so we have to take the minimum of the two
sources' offsets to get all zones on board.

[ChangeLog][QtCore] Introduced Q_NODISCARD_CTOR which resolves to
[[nodiscard]] attribute for constructors on compilers that support
it, and does nothing on other compilers.
Using [[nodiscard]] attribute on a constructor is a C++20 feature,
however in practice it is supported on most of the compilers that
we use in Qt 6. Clang generates a [-Wunused-value] warning, GCC
and MinGW generate a [-Wunused-result] warnings, and MSVC
generates a C4834 warning.
However, there are some exceptions.
The Integrity compiler provides the following warning:
"tst_qglobal.cpp", line 699: warning #3435-D:
the "nodiscard" attribute doesn't apply to constructors,
destructors, or routines with void return type
[[nodiscard]] explicit Test(int val) : m_val(val) {}
The QNX compiler (QCC 8.3.0) and GCC 9.3.1 on OpenSUSE generate
the [-Wattributes] warning:
tst_qglobal.cpp: In member function
'void tst_QGlobal::nodiscardConstructor()':
tst_qglobal.cpp:699:44: warning: 'nodiscard' attribute applied to
'tst_QGlobal::nodiscardConstructor()::Test::Test(int)' with void
return type [-Wattributes]
[[nodiscard]] explicit Test(int val) : m_val(val) {}
These warnings will lead to build failures when compiled with
-warnings-are-errors flag, so for these compilers the macro
does not do anything.
An attempt to use __attribute__((__warn_unused_result__)) was
also unsuccessful on these compilers, so this patch goes for
an easy solution, and simply checks
__has_cpp_attribute(nodiscard) >= 201907L
to decide if the attribute is supported or not.
This commit also introduces a syntax-only test, and also applies
the new macro to QMutexLocker, because not all platforms in the
CI build and run unit tests.

In Qt >= 6.1, < 6.5, a trivially constructible type would have the
NeedsDestruction flag set, but it's dtor pointer would have been null.
In Qt 6.5, the meaning of the NeedsDestruction flag was changed to be
more aligned with what the name suggests, and thus would only be set for
non-trivially destructible types. For QMetaType this was fine, but
QVariant has a check for acceptable metatypes which attempts to verify
whether a QMetaType is usable for QVariant. The check assumes the
semantics of Qt 6.5, and thus fails for metatypes created by older Qt
versions.
To fix this issue, we increment the QMetaType revision field, and only
check the metatype's destruction support if the revision is high enough.
In theory, that allows passing unsuitable metatypes from older Qt
versions to QVariant; however, such code would have been broken in prior
Qt releases already (which didn't attempt the check), and no code that
used to work in any released Qt version will break (as we simply skip a
check that was passing before).

Functions in Qt that take a callback need to support callables with or
without context objects, and member functions of an object. The
implementation of those overloads follows a pattern that ultimately
results in a QSlotObjectBase implementation being created and
passed to an implementation helper that takes care of the logic.
Factor that common pattern into a new helper template in QtPrivate
that returns a suitable QSlotObjectBase after checking that the
functor is compatible with the specified argument types.
Use that new helper template in the implementation of
QCoreApplication::requestPermission and QHostInfo::lookupHost.
The only disadvantage of centralizing this logic is that we cannot print
a more detailed error message indicating which argument types the
caller expects. However, that information is visible from the detailed
