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.

Layout items with a Preferred size policy would be treated as fixed
size if they were in the same layout as an Expanding item (or one with
a stretch factor).
This occurred e.g. if a layout was configured similar to this:
1. One item with ExpandFlag/stretch but with a maximumSize set,
e.g. (100x100).
2. Another item with 'just' GrowFlag, and a maximum size bigger than
its size hint.
If the above layout was resized to e.g. (200x50) it would cause the
expanding item to correctly get the size (100x50), but the 'growing'
item would not stretch beyond its size hint.
Instead, it would distribute space around both items, behaving as if
the 'growing' item was fixed'.
The expected behavior is to continue to grow the 'growing' item after
the expanding item has reached its size limit.

Previously if l had a parent, addChildLayout would warn and skip the
reparenting, but it would still add the sub layout to the layout.
This caused some inconsistencies in the hierarchy which in worst case
could cause crashes.
