The files (folders) already processed are listed in each issue in epic
QTBUG-134547

These files were processed half a year ago. In order to make it clear
that all of these files are already processed, mark them with an
explicit default security header.

For the record, this was generated with this script:

find -E . -regex ".*\.(cpp|h|hpp|mm|qml|js)$" | xargs python3 ~/bin/add-cra-header.py

in the folders listed in each subtask of QTBUG-134547

(add-cra-header.py only exist at my desktop, but it simply adds the
default security header if it doesn't already have any existing security
header)

It seems that the old code assumed that all widths and heights were
limited to integers (despite that the argument was qreal)

Including moc files directly into their classes' TU tends to improve
codegen and enables extended compiler warnings, e.g. about unused
private functions or fields.

From now on we prefer nullptr instead of 0 to clarify cases where
we are assigning or testing a pointer rather than a numeric zero.

Also, replaced cases where 0 was passed as Qt::KeyboardModifiers
with Qt::NoModifier (clang-tidy replaced them with nullptr, which
waas wrong, so it was just as well to make the tests more readable
rather than to revert those lines).

Now that qmlInfo actually reports info messages, we want to change
existing callers to use warning-level messages to preserve the original
message level.

This was done through:
    perl -p -i -e "s/qmlInfo\(/qmlWarning\(/" **/*.{cpp,h,qdoc}
.. with a little care taken to only add the hunks that should be changed.

Storing the anchor-loop-detection counters in a bitfield has the
disadvantage that the full field has to be read and masked in order to
use (increment) them. The same for the subsequent store. By putting them
in their own byte, this can be done a lot faster. Those bytes were
available, because they were needed for padding. By making them signed,
there is also no need for the compiler to insert overflow handling.
