The q_items list is only used to hold a full list of all items in the
layout. They are kept in order for a linear layout, so that users see
them in the right order, but there's no real guarantee for that anyway
if combined with spacers and other non-items.
Continue to try keeping the order, but ensure indices that are out of
bounds are treated as appends to the list.

For gridlayout items the x position is rounded, but the QRectF changes
the width to keep the right edge. The width is yet calculated exactly
for the text so we need to preserve it.

Including math.h can pollute the default namespace, and break
some compilers if cmath versions of the method are declared as using.
Switching to C++ math functions also greatly simplifies handling of
float qreal as C++ automatically chooses the right method.
[ChangeLog][QtCore][QtMath] qmath.h no longer includes math.h, so any
sources depending on that indirect inclusion may fail to build.

Qt copyrights are now in The Qt Company, so we could update the source
code headers accordingly. In the same go we should also fix the links to
point to qt.io.
Outdated header.LGPL removed (use header.LGPL21 instead)
Old header.LGPL3 renamed to header.LGPL3-COMM to match actual licensing
combination. New header.LGPL-COMM taken in the use file which were
using old header.LGPL3 (src/plugins/platforms/android/extract.cpp)
Added new header.LGPL3 containing Commercial + LGPLv3 + GPLv2 license
combination

This enables us to do more intelligent distribution than simply doing the
rounding on each individual items geometry (which often leads to larger
spacings than specified).
Instead of doing the rounding on the output geometries, we now do the
snapping inside the layout engine. This allows us to do more intelligent
distribution of items, and spacings should always be respected.
There are some cases where items with fractional size hints might overlap
with less than a pixel. This was also the case before this patch. Those
cases are impossible to fix properly, since fractional size hints
conflicts with the snapping in some cases.
(Fractional size hints is normal for Text items.)

The problem was that the span we stored in the multiCellMap was the
"effective" span (i.e. the given span subtracted with the number of
ignored rows it would span). Later we used that span to distribute its
size across all its cells. However, since the span now could be smaller
that the given span, we could sometimes fail to distribute to the last
span(s).
[ChangeLog][QtWidgets][layouts] Fixed a bug where spans sometimes didn't
distribute themselves to the last cells they covered.

It can be removed now because we now have a better caching
mechanism than before. It should therefore not be needed anymore.
Since nothing else calls hasChanged, we can finally get rid of it.
This simplifies the code and enables us to further improvements to the
code.

This tests
* default spacing
* explicit positive spacing
* negative spacings
Negative spacings that causes the layout to shrink down to 0 or
a negative spacing are not supported.
(But make sure they don't crash the whole engine)
This is a partial cherry picked from

Only the Q_ASSERT had to be cherry-picked. This is because of that the
qgridlayoutengine* is moved to qtbase.
Therefore, any changes to qgridlayoutengine* won't be merged properly to
dev (they will be lost).

For MacOS 10.6 the exported symbols must be the same regardless of
debug/release configuration, because for debug builds it will by
default link to a release library.
We therefore cannot let some exported symbols depend on if QT_DEBUG
is defined or not. We therefore introduce QGRIDLAYOUTENGINE_DEBUG,
which is independent of debug/release configuration.
The whole dump() function concept should probably be revisited, but
I don't want to clutter this commit too much with such unrelated
things.
