QTreeView makes columns movable except for the first one
(since Qt 5.0, see commit e0fc088c0c). This is indeed best
for actual trees, but not when using QTreeView as a flat
multi-column list (with no "root decoration"). Then it should
be possible to move the first column.
[ChangeLog][QtWidgets][QHeaderView] Flat treeviews can now allow
the user to move the first column (like in Qt 4.x) using the new
method QHeaderView::setFirstSectionMovable().

It hasn't been necessary for a long time now to write the recursive

Demonstrate the new QLocale::formattedDataSize() function.

The Main Window example generates icons programmatically for its

QFontMetrics(F)::width() has been deprecated and is replaced by
horizontalAdvance(). This updates all usage of it in tests and
documentation.
It is worth noting that many or most of the usages of
QFontMetrics::width() probably intended to use boundingRect().width(),
but since it currently works, I have not looked into that, just
replaced the function name mechanically.

The vast majority is actually switched to QRandomGenerator::bounded(),
which gives a mostly uniform distribution over the [0, bound)
range. There are very few floating point cases left, as many of those
that did use floating point did not need to, after all. (I did leave
some that were too ugly for me to understand)
This commit also found a couple of calls to rand() instead of qrand().
