3ffc471385 Accessibility: make sure childAt calls isValid
Generally isValid should be called by the bridge, but in this case, we
must verify the validity internally since we derefernce the interface
internally.

8b64f93362 Ensure that RC_FILE is correctly handled in a single configuration
When generating the Visual Studio project XML, the filter "Root Files"
was not being output. Specifically, this means that even if RC_FILE was
specified, it would not be included properly as a resource compilation
target in the resultant Visual Studio project file.

This is essentially a rather belated cherry-pick of qt/d6de960b7f.

64666b9ee0 Windows: Check if the fallback key matches the shift modifier case too
There are some keyboard layouts where pressing shift will give something
different to what the expected key would be. For example, on a French
keyboard layout, pressing SHIFT+! gives 1 as opposed to SHIFT+1 giving
! on a US keyboard layout. Therefore it should check against both cases
to ensure it does not end up adding a new entry.

1d1b60dee4 QStylesheetStyle: don't lose precision when drawing a progress bar
When qreal is float, it cannot represent all values an int can take,
so we may lose precision in the expression

  qreal(a) / b

as opposed to the double result

  double(a) / b

For lack of trying, I do not know of a value where this would change
the resulting 'fillWidth' value, but better be safe than sorry, and
use double instead of qreal arithmetic.

Also, when calculating fillRatio, we were converting values back and
forth between qreal and double. Using double everywhere avoids that.

the code for setting up rpath now also sees the longer list of

sub-projects just adds noise to the make output and misleads users.

note that this specifically does not support qmake -r, which will break
if the subprojects rely on the arguments being absent. this isn't a
problem, because the qt build doesn't support qmake -r anyway.

52d64fca66 revert to building qmake with qconfig.cpp
turns out that just appending builtin-qt.conf isn't a good idea:
executable-editing tools (objcopy, prelink, etc.) will happily drop the
"attachment".

a safe method would be adding a proper section to the executable, but
there doesn't appear to be an objcopy equivalent in msvc, and using
entirely different methods of embedding the file with different
toolchains seems like a rather bad idea.

so instead go back to the old method of building qmake with a generated
qconfig.cpp. of course, as said file is now created by qmake itself, we
have to compile qlibraryinfo.cpp a second time, and link a second qmake
executable.

17b6967f68 don't unnecessarily pass -qtconf to qmake
it makes the call more noisy for no particular reason.
and the new code is even easier to read ...

cfba3fff05 move emission of final messages to qmake-based configure
now qmake is the last command called by the unix configure script.
as it happens, this was already the case in the windows script, but only
because it didn't print these messages at all, which it implicitly does
now.

another effect of this is that repositories outside qtbase will now also
get the installation note in modular builds, which makes sense.

4a738424aa Fall back to platform theme in QPlatformSystemTrayIcon::createMenu()
Commit 824f08046 introduced QPlatformSystemTrayIcon::createMenu() as a way
for platforms to provide a system tray menu independently of the menu
created by QPlatformTheme::createPlatformMenu(), which would on some
platforms be null.

Commit 063997f44f then made menu creation lazy, which meant that the
logic in QSystemTrayIconPrivate::addPlatformMenu() to create the menu
turned from "create menu via QPSTI::createMenu() if QPT::createPlatformMenu()
returned null", to "create menu via QPSTI::createMenu() if menu was not
created yet". The latter logic relied on each platform having implementations
of QPlatformSystemTrayIcon::createMenu() which they didn't, resulting in
missing menus for system trays on e.g. macOS.

With the new lazy logic, the reasonable approach is for the default
implementation of createMenu() to use createPlatformMenu(), which will
ensure system tray menus on platforms that implement createPlatformMenu(),
while still allowing platforms that don't to override createMenu() for
special-casing system tray menus.
