2e02de1651 Fix QtDBus deadlock inside kded/kiod
Whenever a message spy was installed, we failed to actually process
looped-back messages by queueing them for processing by the spy. That
had as a consequence that the caller got an error reply. Worse, since
the message had been queued, QtDBus would attempt to deliver it later.
Since that message had isLocal==true, bad things happened inside the
manager thread.

The correct solution is not to queue the message for the filter. If the
message is local, then simply deliver directly, as we're still in the
user's thread. This used to be the behavior in Qt 5.5.

7c7ece9442 QMacStyle: Ensure proper focus ring clipping
By rendering the focus ring directly on the backing NSView, we
would ignore the painter's clipping information. It would also
require creating a custom CGContext and attached NSGraphicsContext
every time.

The first step is to render the focus ring on a pixmap and then
use the painter to render that pixamp. This ensures the clipping
is done properly. The second step is to cache said pixmap and
render it as a nine-patch image.

0307c008bf Make QWindowsPipeWriter thread-free.
Re-work QWindowsPipeWriter to not use a thread anymore but the
WriteFileEx API, similar to QWindowsPipeReader. This saves us a lot of
thread synchronization code and enables us to directly write data
without yet another buffering layer.
  Also, this fixes the dreaded deadlocks in the QWindowsPipeWriter
destructor that could occur when the reading end was closed before
the write was finished.

5c89e2eeee Rework QWindowsPipeReader
The use of QWinOverlappedIoNotifier in QWindowsPipeReader restricts us
in the following ways:
  - The handle that gets assigned to QWinOverlappedIoNotifier is forever
    tied to an I/O completion port.
  - Other notification mechanisms like I/O completion routines of
    WriteFileEx do not work with such a handle.
  - No other QWinOverlappedIoNotifier can be registered for this handle.

To achieve the ultimate goal of making QWindowsPipeWriter thread-free
(to fix QTBUG-23378 and QTBUG-38185) we remove the usage of
QWinOverlappedIoNotifier from QWindowsPipeReader and use the
ReadFileEx API instead.
This has the additional advantage of removing the need for any thread
synchronization, as the I/O completion routine runs in the thread that
ReadFileEx was called on, leading to simpler and faster code.

09acf326db QCocoaMenu: Decouple NSMenuItem from NSMenu
While Cocoa requires an NSMenu to be coupled to an NSMenuItem
(just as Qt requires a QMenu to be coupled to a QAction), making
that a hard coupling comes with some limitations. This is because
Cocoa won't allow the NSMenu object to be simultaneously coupled
to more than one NSMenuItem and, similarly, an NSMenuItem can
only be added to a single parent NSMenu. Therefore, it becomes
difficult to share one QMenu between two different QMenuBars in
different windows, or to use a QMenu as context menu while being
accessible from the menu bar.

Previous solutions to circumvent those limitations were less than
ideal (see 119882714f for the
QMenuBar shared QMenu issue). Other workarounds that relied on
that hard coupling, like 996054f5e6,
also added gratuitous complexity.

In this patch, we break that hard NSMenuItem-NSMenu coupling, and
we replace it with a temporary, looser coupling. As a consequence,

   * QCocoaMenu only contains and manages a NSMenu instance,
     removing the previously used NSMenuItem. It gets a temporarily
     attached NSMenuItem instead.
   * QCocoaMenuItem gains a safe pointer to its QCocoaMenu property
     removing the necessity containingMenuItem() in QCocoaMenu.
   * QCocoaMenuBar manages its own NSMenuItems.

With this setup, we bind the NSMenu to its parent NSMenuItem at the
last moment. In QCocoaMenuBar, when we call updateMenuBarImmediately().
In QCocoaMenu, we use the delegate's -[QCocoaMenuDelegate menu:
updateItem:atIndex:shouldCancel:] method which is called when Cocoa
is about to display the NSMenu.

Note: There's still one use case we don't support, which is sharing
a toplevel QMenuBar menu. This is because Cocoa's menu bar requires
each of its menu items to have a submenu assigned, and therefore we
can't rely on that last moment assignment.

c27d4eeac6 don't force our runpath upon user projects anymore
now that we rely on consistently sane runpath semantics everywhere

in forcing our runpath downstream: our libraries will find their
dependencies due to their embedded runpath.

523c7e3fd5 build with explicitlib after all
unlike speculated in 2fe363514, this is not a workaround at all: it
causes that libraries' public link interfaces (LIBS) are exported in the
first place. unlike with staticlib, this does not export LIBS_PRIVATE,
so it wouldn't even be a particularly effective workaround for rpath
brokenness anyway.

the problem was pretty well hidden by the qt module system, which at the
level of libraries is pretty redundant with the .prl file handling,
which shows just how stupid the whole "design" is.

unlike before, we now enable explicitlib for all libraries, not just qt
modules - we enable create_prl for all of them as well, after all.

an immediate effect of this change is that it fixes linking on RaspPI:
the qtcore headers make the user code require linking libatomic, so we
must add it to our public link interface.

However, the windows backend does query the registry heavily, which is

Long-term we might want to switch to this version on desktop windows as

e4c6d73f92 QRect: fix UB (int overflow) in center()
QRect::center() should be defined for any
  QRect(x1,y1,x2,x2), INT_MIN <= x1, x2, y1, y2 <= INT_MAX
because the average of two signed integers is always
representable as a signed integer.

But not when it's calculated as (x1+x2)/2, since that
expression overflows when x1 > INT_MAX - x2.

Instead of playing games with Hacker's Delight-style
expressions, or use Google's patented algorithm, which
requires two divisions, take advantage of the fact that
int is not intmax_t and perform the calculation in the
qint64 domain. The cast back to int is always well-
defined since, as mentioned, the result is always
representable in an int.

Fix a test-case that expected a nonsensical result due
to overflow.

[ChangeLog][QtCore][QRect] Fixed integer overflow in
center(). This fixes the result for some corner-cases
like a 1x1 rectangle at (INT_MIN, INT_MIN), for which
the previous implementation could return anything
(due to invoking undefined behavior), but commonly
returned (0, 0).

5784c064a9 tst_QRect: drop a test that depends on int overflow
The compiler can statically check that this is undefined
behavior:

  tst_qrect.cpp:3173:52: warning: integer overflow in expression [-Woverflow]
               << QRect(QPoint(0,0), QPoint(INT_MAX+(0-INT_MIN),INT_MAX+(0-INT_MIN)));
                                                   ~^~
  tst_qrect.cpp:3173:72: warning: integer overflow in expression [-Woverflow]
               << QRect(QPoint(0,0), QPoint(INT_MAX+(0-INT_MIN),INT_MAX+(0-INT_MIN)));

Fix by skipping the test (like most of the others are
in the block).

b4fa18a996 Revert "Handle the QWidgetPrivate::mapper structure"
This reverts commit 90de48493be283b9afb249f6a0fd8dbd8958517d.

The call isn't necessary, but invokes undefined behavior.

It invokes undefined behavior because deleteTLSysExtra() is called
from deleteExtra(), which is called from ~QWidgetPrivate(), which is
called from ~QObject(). Thus, by the time we call q->windowType()
within setWinId(), q is no longer a QWidget, but only a QObject, and
calling a QWidget member function then is UB.

UBSan confirms:

  qwidget_p.h:300:5: runtime error: downcast of address 0x2afdd4053620 which does not point to an object of type 'QWidget' (the Q_Q macro)
  0x2afdd4053620: note: object is of type 'QObject'
  qwidget.cpp:1712:93: runtime error: member call on address 0x2afdd4053620 which does not point to an object of type 'QWidget'
  0x2afdd4053620: note: object is of type 'QObject'

It is also unnecessary:

deleteTLSysExtra() is called from two places: QWidget::destroy() and
deleteExtra(). deleteExtra() is only called from ~QWidgetPrivate()
which is only called from ~QObject() called by ~QWidget(), which,
however, already calls QWidget::destroy(). QWidget::destroy(), in
turn, unconditionally (for non-desktop widgets, at least) calls
setWinId(0) itself.

So fix the UB by removing the call without replacement.

add95c5510 tst_QSqlQuery: fix UBs (invalid downcasts, member calls)
The existing code derived a helper class from QSqlResult and
overloaded two protected functions as public ones so the test
could call them after casting QSqlResults to that helper class.

Both the cast (which is a C-style cast, but with combined
static_cast and const_cast semanics) and the following member
function call are undefined behavior.

Fix by making the test class a friend of QSqlResult, and
dropping the casts.
