Since the removed function has an inline definition, it suffices to

We have in the past found ourselves in need of disambiguating new
overloads from older, QT_REMOVED_SINCE'ed ones, which we usually did
by adding a defaulted int argument, cf. e.g. QMetaType::id().
The problem with a defaulted int argument is twofold: First, an int is
a valid argument type, and users may get confused as to its meaning
when presented with the signature in the IDEs auto-completion popup,
and a lot of things implicitly convert to an int, so any errornous
parameter passing may stay unnoticed until we remove these fake
arguments come Qt 7.
Second, this way of doing things requires a lot of ifdef'ery to keep
the additional argument out of both the docs and future Qt 7 builds.
The solution presented in this patch is to create a tag type,
QDisambiguated_t, which a) more clearly communicates its purpose and
b) doesn't implicitly convert from anything.
To help with the invariably ugly ifdef'ery, provide a set of macros
that hide this stuff from qdoc and Qt 7 builds.
Use the macros to replace the fake int arguments that were added for
6.4.

43ef22045c turned dark mode support on for
both styling and window frames. However, the default palette and style
support in Qt is too incomplete, resulting in unreadable UIs when using
certain styles (e.g. fusion). Also the vista style is not supporting
dark mode.
If we don't turn on dark style support, then dark frame support doesn't
look good either. However, many application developers have implement a
dark theme themselves, and we should have a dark frame for those
applications.
So partially revert 43ef22045c so that
dark style support is disabled by default, and leave dark frame support
on. However, only activate dark frames if the palette is dark, i.e. if
the window background color in the default palette is darker than the
text color (or if DarkModeStyle is explicitly turned on by running the
application with -platform windows:darkmode=2).
This way, dark-themed applications get a dark frame on dark Windows, and
a light frame on light Windows; and light-themed applications (including
default Qt applications) get a light frame all the time.

So far we always recommended that developers set CMAKE_PREFIX_PATH to
point to the location of the Qt installation so that Qt packages are
found by CMake.
In Qt5 one could also set the Qt5_DIR variable to $qt/lib/cmake/Qt5
to allow the following signature to work:
find_package(Qt5 COMPONENTS Core)
This was not sufficient in Qt6 because the CoreTools dependency would
not be found.
Fix this by also looking into the parent folder of
CMAKE_CURRENT_LIST_DIR as well as _qt_cmake_dir, like we already do
for regular non-Tools packages in _qt_internal_find_dependencies.
Note that setting Qt6_DIR is not sufficient for cross-compilation if
the qt.toolchain.cmake file is not used.
Aside from platform specific options that would have to be passed
manually to CMake (like -DCMAKE_SYSTEM_NAME=iOS for iOS) and
passing a QT_HOST_PATH value, the code would also need to be
adapted to do the necessary CMAKE_FIND_ROOT_PATH manipulations
to ensure that dependent packages are found.

We were allowing up to 1 million elements for each array, which meant 16
MB (32 for maps), and we considered that sufficient. However, because we
do allow up to 1024 levels of recursion, the memory consumption was
actually limited to 16 GB (32 for maps), which is a bit too high for
64-bit applications, and definitely too high for 32-bit ones.
So further clamp down, to a mere 16k elements on 32-bit and 64k on 64-
bit, which limits the memory use to 256 MB on 32-bit and 1 GB on 64-bit.
And additionally apply this exact limit to maps, instead of allowing
them to double the size.

fork() works by implementing Copy-On-Write for all pages that either the
parent or the child process write to. So if the parent process continues
running while the child is between fork(2) and execve(2), then it will
keep causing page faults and requiring the OS to duplicate those pages,
which may be expensive (page table updates, TLB flushes, etc.). This
problem is aggravated if the parent process is multithreaded, as the
simple act of running in the parent will cause those threads' stacks to
cause page faults.
The BSD solution for that was vfork(), which has two differences in
behavior: (1) it blocks the parent from running and (2) it shares memory
with it. But it's always been tricky, so POSIX.1-2001 deprecated it and
2008 removed its definition completely. Still, it is available somewhat
widely, and on Linux that can be achieved with clone(2) and the
CLONE_VFORK and CLONE_VM flags, for those two behaviors respectively.
Because of (2), we can't return from the forkfd() function in the child
(as that would trash the stack in the parent process), so to implement
this functionality vforkfd() adds a callback of the same signature as
glibc's clone(2) wrapper (something that hadn't occurred to me when we
attempted to use CLONE_VFORK last time).
On Linux, (1) is no problem, as clone(2) has native forkfd support. But
on other OSes, forkfd() requires the parent to run before the child
execve()s, in order to save the child PID in the list of children we're
going to handle SIGCHLD for in a non-racy way. Investigating if it is
possible to use vfork() anyway is left as an exercise for the reader.

Refactoring of the logic around QWasmCompositor::processMouse has been
performed for readability and easier modification, in preparation for
further fixes for event delivery and handling in windows. There should
be no logic changes, just cleaner code.
Change groups:
Members of QWasmCompositor have been prefixed by m_ for easier discerning
of stateful and stateless variables in functions.
Variables renamed to more descriptive, e.g. window2->targetWindow,
globalPoint->targetPointInScreenCoords.
Magic numbers eliminated, e.g. mouseEvent->button == 0 is now
button == Qt::MouseButton::LeftButton.
Some common condition checks have been wrapped into single constants,
e.g. !(htmlWindow->m_windowState & Qt::WindowFullScreen) &&
!(htmlWindow->m_windowState & Qt::WindowMaximized) ==
isTargetWindowResizable
Some nested if-conditions were collapsed.
Some unnecessary checks have been moved to outer if conditions (e.g. for
draggedWindow in EMSCRIPTEN_EVENT_MOUSEMOVE, since the code would crash
anyway because only some parts are guarded against it being nullptr).
Consts introduced so that variables are only used for one purpose.
Made QWasmEventTranslator::translateMouseButton constexpr
Made QWasmWindow::isPointOnTitle behave correctly when the window has
no title bar so that no flag probing is needed prior to calling it.
Made QWasmCursor::setOverrideWasmCursor accept a const ref - having it
accept pointer suggested it might dangle.
