QLayout(QWidget *parent) directly calls parent->setLayout(this) which
can lead to a runtime warning later on when someone tries to set the
layout on the parent again.

This was the missing counter-part to indexOf(QWidget *), which is
sometimes implemented in user code.
Not sure why the original code doesn't use a for-loop and instead accesses
an out-of-bounds element, but I'll preserve the behavior of very old working code.

We can't just static_cast a child to QLayout, because the child might
not be a QLayout, and even if it was, we might be called from the
QObject destructor so we would not be a layout anymore.
Instead we can just qobject_cast the deleted object to a QLayout and
remove it from the layout with removeItem.
This would not take in account the case where we would be called because
the QLayout gets destroyed, so we handle this case from ~QLayout by
removing ourself from the parent.
Note that the comment in ~QLayout was wrong, as the layout gets destroyed
explicitly from ~QWidget, not from ~QObject.

Tell the compiler so it can move the error handling

This change contains the changes to the accessible/,

we could always use Q_UNLIKELY, instead of having to
revert to Q_LIKELY here and there.
In QWidgetPrivate::setWindowModified_helper(), as a

more readable and more efficient (cheaper check
first) at the same time.
In qDraw* (qdrawutil.cpp), simplified boolean

Since we cannot support heightForWidth constraints on toplevel
windows, it is impossible to solve this perfectly: if the
window is resizable at all, the user will be able to resize it
too small. Our old solution was just to give up and allow
completely free resizing, even down to 0x0. This makes
very little sense. It is clearly better to use the minimum
size that we have already computed, even though it is not
perfect.
This reverts a behavior change introduced in commit

Widgets and layouts added or inserted to a layout are checked for:
- Not being NULL
- Not being the parent widget of a layout or the layout itself,
respectively
Without this commit, adding a widget to its own layout would result in a
CPU-hogging infinite loop. Now, a warning is written to stderr and the
add or insert function call is ignored.
The checks are implemented as public functions of QLayoutPrivate and
thus accessible in QLayout's descendants to be used in various
"addWidget", "insertWidget", etc functions.
Unlike 'classical' layouts like QGridLayout, QFormLayout does indeed
accept widgets that are NULL. To not break this behavior, any call for
the check functions first tests if the widget or layout, respectively,
to test is NULL or not and calls the check only in the latter case.
Automated tests for QBoxLayout, QGridLayout, and QFormLayout were added.
For an unpatched Qt 5.3, each of those automated tests will freeze as
explained in QTBUG-40609. For a fixed version, warning messages about
invalid parameters to addWidget/addLayout/... calls will be read by
QTest::ignoreMessage, resulting in a passed test.

If the menu bar is subject to height for width (HFW) we should of
course respect that, but in addition we should ensure that the HFW is

QGridLayout calculates the effective minimum row height.
This fixes a regression because change 4780f94e391b5e881497c5228661dead
