8738d9a6a8 QVariant: move the check for std::nullptr_t a bit up in customConstruct
Avoids having to do work after QMetaType::construct() returns. That
can't get the tail-call optimization right now because it is a non-
inline non-static member function, so the QMetaType must be spilled to
the stack.

In one of the three calls to customConstruct() -- QVariant::detach() --

2e6398bd46 QMetaType: don't record trivial construction function pointers
We can implement the trivial {default,copy,move} construction outselves
inside qmetatype.cpp and qvariant.cpp, simplifying the QMetaType
interface object, removing up to three relocations per QMTI.

This adds the testing for QMetaType::isXxxConstructible and
isDestructible that couldn't be added before.

effc8be3ce Add nullptr guard in QStyleSheetStyle::drawPrimitive(PE_PanelLineEdit)
Drawing PE_PanelLineEdit in QStyleSheetStyle with the default argument
widget = nullptr causes a segfault.

drawPrimitive tries to fall back to a container widget's render rule
and therefore calls containerWidget() - which crashes when called with
nullptr.

Container widget fallback is pointless when drawPrimitive() is called
with widget == nullptr. This patch skips it in that case.

0e0352ab4d CMake: Fix install destination of in-tree examples
Previously we called _qt_internal_override_example_install_dir_to_dot
in Qt6CoreConfigExtras.cmake as part of a
find_package(Qt6 COMPONENTS Core) call, and we assumed that the
Extras file would always be included in each example project.

But our package dependencies handling code skips calling
find_package(Qt6Core) if Qt6Core_FOUND is already set to TRUE,
which will definitely happen due to root-scope find_package
calls when configuring other repos.
That means we wouldn't override INSTALL_EXAMPLEDIR to "."
and the install destination would end up being something like
${CMAKE_INSTALL_PREFIX}/example_relative_path/example_relative_path
aka a double nested path.

Make sure we call the
_qt_internal_override_example_install_dir_to_dot function
in Qt6ConfigConfig.cmake in addition to Qt6CoreConfig.cmake.

That way, even if Qt6Core is skipped during dependency resolution,
it's still handled by the Qt6 package itself.

Because the function is defined in the Core package, guard the call
with an if(COMMAND) and only call the function if it wasn't previously
called within the current or ancestor scopes.

578f4ba00c CMake: Add per-target support for iOS launch screens
To support per-target iOS launch screens we need a way to specify
custom Info.plist entries without using cache variables, which we were
forced to use due to the implicit configure_file done for
MACOSX_BUNDLE_INFO_PLIST.

We now introduce an extra configure_file call done in a finalizer,
before we hand off the Info.plist file to MACOSX_BUNDLE_INFO_PLIST.

This extra configure_file call allows us to insert / substitute
additional Info.plist entries that CMake does not allow setting.

If a custom Info.plist file is provided, the finalizer will simply
skip the logic for creating a new one.

999654fec7 QByteArray: inline QByteArray::isNull()
Keeping it out-of-line is unnecessary and has been since 5.0. In Qt 4.x,
it was necessary to compare to the shared_null, which for QByteArray was
a static variable. The one for QString has always been inline because
the shared null was a static member of QString (in Qt 3, QString::null
was a QString variable).

74fac865cf QMetaType: add registerType() and qRegisterMetaType(QMetaType)
This also rewrites QMetaType::id() on top of the helper, with the benefit
of calling a member static function, so QMetaType doesn't need to be
spilled onto the stack. In some upcoming changes I need to ensure that
QMetaTypes are registered so they can be found by name and I'd like to
have a dedicated function name for that, instead of calling .id().

Since I needed to add docs for the new function, I've updated for the
old one too.

[ChangeLog][QMetaType] Added QMetaType::registerType() and an overload
of qRegisterMetaType() taking QMetaType (the two functions do the same
thing). These two functions ensure a given QMetaType is registered with
the Qt global registry, so they can be found by name later. Using
qRegisterMetaType<T>() also accomplishes the same thing, but is slightly
better for completely generic code because it will avoid emitting the
registration for built-in types.

f73833809b Fix QString::vasprintf for strings > 2GiB
Both format strings > 2GiB, as well as result strings > 2Gi characters
were affected by the append_utf8() helper function being left unported
from int to qsizetype.

There were actually two bugs in that 5LOC function:

1. The len argument was an int, but the caller feeds a difference of
   pointers (even explicitly cast to qsizetype) to the function, so
   any stretch of verbatim text > 2GiB in the format would cause the
   output string to be corrupted.

2. If the result string was already > 2Gi characters in size, a call
   to append_utf8() would truncate it mod INT_MAX, because the
   string's size() was stored in an int variable and the used in a
   resize() call.

4720735103 CMake: Change __qt_internal_include_plugin_packages to be a macro
The __qt_internal_include_plugin_packages function includes
PluginConfig.cmake files which in turn might look for dependencies
with find_dependency. The dependencies that were found not have their
_FOUND variables set in the calling scope, which could cause multiple
lookups of the same dependency packages.

Change the function to be macro, so that all relevant _FOUND variables
are set and no unnecessary package lookups are done.

As a result, no need to set the QT_ALL_PLUGINS_FOUND_BY_FIND_PACKAGE
variable using set(PARENT_SCOPE)

63db26a47e CMake: Don't look for Qt6 components that are already found
This matches what we do in Dependencies.cmake files, except this time
for COMPONENTS passed to the Qt6 package.

For example if a project does
 find_package(Qt6 COMPONENTS Widgets Core)
we'd end up looking for Core twice. Once as a dependency of Widgets
and once as a standalone request of the project.
Make sure to skip the second lookup if it was already found.

3892e86d6e CMake: Don't unset Qt6Qml_FOUND when including Qml plugins
Removing the variable would cause nested find_dependency calls of
FooQmlPluginDependencies.cmake files to look for the Qml package
again and again.

If we got to the point of including QmlPlugins.cmake, we already know
that the Qml package was found.

Set it to TRUE after every inclusion to avoid repeated Qml package
loading.

The second inclusion pass will ensure to set the found variable to
FALSE in case if some dependency is actually missing.

dffcc2370e CMake: Record the precise package name where Private modules live
Previously if a target depended on CorePrivate, we would write a
_qt_internal_find_qt_dependencies(... Qt6CorePrivate) call into a
FooDependencies.cmake file.
That find_qt_deps call would remove the 'Private' suffix and would run
find_dependency with NAMES set to both the altered and non-altered
names.
This would find the relevant package but it would set the wrong
_FOUND variable name, e.g it would set Qt6CorePrivate_FOUND instead
of Qt6Core_FOUND.
This in turn could cause multiple lookups of the Qt6Core package
during dependency handling because the correct _FOUND var would not be
set.

Instead of always looking for the Qt6CorePrivate package, make sure
we look for an appropriately named package for all Privates modules,
because we have the necessary info to determine the correct name.

Note that INTERNAL modules will still be looked up via a Private
suffixed package name because that's how the package name is chosen
for them.

Remove the code that accounted for Private modules in
qt_internal_remove_qt_dependency_duplicates because it's not needed
anymore.

Warn when a package name can't be queried from a target's property
because the target might not exist yet.

Add a TODO comment for the code that searches with two NAMES.
We can't remove it right now, because it might break user projects
that use stale Dependencies.cmake files.

The dbus subdirectory is added before the tools subdirectory
to ensure that the new package name extraction does not error out, due
to trying to access a target that does not yet exist.

d48e596b3c CMake: Split 3rd party libs to be built before and after corelib
The ZLIB and the PCRE2 should be created before Core, because
src/corelib does qt_find_package to find the bundled / built
libraries.

The libpng, libjpeg, and the rest of the 3rd party libraries should be
created after the Core target is created, because they reference
Core conditionally in qt_internal_extend_target.

Targets should ideally be referenced only after they are created, when
creating linking relationships, but if code needs to extract
properties from those targets, then the targets must exist.
This will be the case in a future change which will extract the
package name from a target's property via qt_internal_extend_target ->
qt_register_target_dependencies chain.

976539b4af CMake: Create aliases for Internal targets using common function
Previously we did not create Qt6:: namespaced aliases.
This is needed as a workaround preparation for getting the package name
of a module target from one of it's properties.

Before it would fail in qtinterfaceframework because
ifvehiclefunctions-simulation-server uses PUBLIC_LIBRARIES
in its qt_internal_add_app call, and because _add_app does not handle
such an option, some weirdness in qtbase's _add_app -> _add_executable
-> _extend_executable -> _register_target_dependencies ended up trying
to register PlatformAppInternal as package dependency.
That issue will be handled in separate changes.

7b24ffa936 CMake: Improve Qt6HostInfo package lookup condition
Instead of checking if QT_HOST_PATH is set during user project
configuration to find out if Qt6HostInfo should be looked up,
record if QT_HOST_PATH was provided during Qt configuration
into Qt6Dependencies.cmake and look up the package in a user
project based on that information.

This improves handling of the case where cmake is directly used
to configure a Qt project (instead of qt-cmake), which means no
QT_HOST_PATH might be set by the user, and then cmake would error out
saying that e.g. Qt6CoreTools is not found, instead of saying that
Qt6HostInfo is not found.
