5e76cb1692 Fix menu position when highdpi scaling
Certain display and scale factor configurations would
cause menus to pop up in incorrect locations or not
be shown at all.

This was due to QDesktopWidget::screenNumber() having
a toNativePixels(QRect, QWindow) call which requires
that QWindow::screen() returns the correct screen.

Break the circular dependency by converting coordinates
the other way for the intersection test: transform screen
geometry to device independent coordinates.

Clang does the same, according to a comment in the code, did not test

Hence, define the fallthrough declaration (as C++11 attributes)
only when compiling as C++, otherwise we pick them up even in C mode,
and they cause build failures.

e0e6cbdacb xcb: prevent dangling pointer when window focus changes
With the current implementation, the QXcbConnection::m_focusWindow
was holding a dangling pointer during the focus transition from a
dying modal window to other modal window.

1) QXcbConnection::m_focusWindow holds a pointer to A;
2) A is closed;
3) relayFocusToModalWindow B;
   => m_focusWindow now points to a dead window.
4) We get a reply back from WM in a respone to
   relayFocusToModalWindow (_NET_ACTIVE_WINDOW)
   => m_focusWindow now points to a valid window.

The fix is to update m_focusWindow to nullptr, when the current
focus window was destroyed and the new focus window has not been
set yet by WM.

This patch actually solves a more general case - whenever we get a
focus-out event, we should set m_focusWindow to nullptr. It is ok
for none of the windows to be in-focus while focus transition is
happening. The focusInPeeker will make sure to "optimize out" (when possible)
this no-window-in-focus state, and GUI won't be bothered by this
extra event. This is how things were working before relayFocusToModalWindow
was introduced. Having a focus-relay mechanism in-between is ok,
but it should not have changed the original behavior.

a03390a8b0 Detect the (stated) C++ standard edition at build time
The configure-time detection (cxx11default) isn't enough if the compiler
can be changed. This is especially necessary if Qt is compiled with a
compiler that defaults to >= C++11 (e.g., GCC 6) and then the user
selects a compiler another compiler (e.g., Clang) via -spec option. In
that case, we'd miss adding the -std=c++11 or -std=gnu++11 option to the
command-line, causing the compilation to fail.

As a nice side-effect, even moc without moc_predefs.h will now get the
__cplusplus setting.

62013d7772 Mark to remove const from function parameters in QtCore public headers
Some compilers are known to complain about this with a warning. GCC
complains about const on return values on -Wignored-qualifiers (enabled
at -Wextra), so it's not too much of a jump to assume that others do
too. Besides, this is not Qt Library API policy. As maintainer for
QtCore, I'm exercising my prerrogative in specifying certain unspecified
parts of the coding style, like I've done for constructor initializer
lists.

Since all the classes involved are exported (including QVector, through
derived classes), we can't remove the qualifier until Qt 6, since there
are compilers known to encode the qualifier in the mangled name
(suncc). I'm not introducing #ifdef to silence unknown compilers unless
we get an actual complaint.

The SHA3 family is a modified version of Keccak. We were

to calculate a SHA3 digest, it calculated a Keccak digest instead.

9a0d47bcf1 tst_largefile: fix the mapOffsetOverflow case to match actual behavior
Unix mmap(2) system calls do allow for mapping beyond the end of the
file, though what happens after you try to dereference the pointers it
gives is unspecified. POSIX[1] says that implementations shouldn't allow
it:
 The system shall always zero-fill any partial page at the end of an
 object. Further, the system shall never write out any modified portions
 of the last page of an object which are beyond its end. References
 within the address range starting at pa and continuing for len bytes to
 whole pages following the end of an object shall result in delivery of
 a SIGBUS signal.

However, Linux allows this in read-write mode and extends the file
(depending on the filesystem).

Windows MapViewOfFile never allows mapping beyond the end.

Q_DECL_OVERRIDE to the keyword in affected classes, to match.

ee84af00d1 Fix floating dock widget having the wrong parent
When dragging out a tabbed group which contains placeholder
for floating QDockWidget, the floating QDockWidget would not
be reparented to the new QDockWidgetGroupWindow. That's because
QDockAreaLayoutInfo::reparentWidgets does not reparent floating
widget (because of the item.skip test)

However, we need to be careful when reparenting to pass the
flags so it does not get docked.
Also do not reparent QDockWidgetGroupWindow which may end up
temporarily in the layout during animation when dragging a
QDockWidgetGroupWindow onto another.

Step to reproduce a crash that if fixed by this patch (with
the mainwindow example):

1. Enable QMainWindow::GroupedDragging from the "Main window" menu
2. Add a new dock widget, "Foo", from the "Dock Widgets"
3. Tab "Foo" together with the black dock widget
4. Drag "Foo" out.  (Now, Foo is still a child of the QMainWindow,
and is still in the layout as tabbed, but is skipped)
5. Drag the black dockwidget out. (This, in fact, crates a
QDockWidgetGroupWindow which contains the black dockwidget and the
floating "Foo", but since "Foo" is floating, it is not reparented)
6. Destroy "Foo" using the "Dock Widgets" menu. (Since Foo's parent
is the QMainWindow, it is not removed from the QDockWidgetGroupWindow's
layout, which will cause crash on the next relayout)"

This commits amends commits d57bb19902
and 0feeb6f6d2

97be8253fb fix bootstrapped modules in framework builds, take 2
the borrowing of headers always happens from "proper" modules which are
actually built as frameworks if so requested. that means that even
though the borrowing module itself never is a framework, it needs a
framework path and include paths that point into frameworks.

87e14eb7cb don't try to use system zlib if it's not enabled
... as that would error out unhelpfully.
but hypothetically, there could be dynamic builds of system libpng and
sqlite3 against a static zlib, so allow it. however, it's a tad
unlikely, so default to -qt-libpng when using -qt-zlib (and -qt-sqlite3
is the default anyway).

amends dab013804.

cd58abb1db Autotest: make tst_QDir more reliable on tests being run out of order
mkdir(data2) depended on mkdir(data1) being run before, or it would
fail. In addition, the rmdir() test required the equivalent mkdir() test
being run before. So drop these annoying dependencies and make the tests
cleaner by having clear separation of the test data and merging the two
tests into one

The entryList() test still depends on the testdir being clean: it will
fail if mkdirRmdir() previously failed.

99fc96fd37 QMetaType & QVariant: "load" and "save" std::nullptr_t
We don't load and save pointers usually because the pointer value cannot
be guaranteed to remain across program invocations. However, nullptr is
an exception: a null pointer is always a null pointer.

We don't actually have to read or write anything: there's only one value
possible for a std::nullptr_t and it is nullptr.

[ChangeLog][Important Behavior Changes] A QVariant containing a
std::nullptr_t is now streamable to/from QDataStream.
