[Development] Preparing to release repackaged version of Qt 4.8.3 with Digia copyrights

[Peter Kümmel]

This discussion shows another problem.

ATM it is not possible to release a Qt4 version
(has Qt5 the same problem?) with a proper version
number based on an already released version and
containing only some patches.

This is not only a scenario when the Qt copyright
changes. It could happen all the time for security
related fixes.

So I think it is worth to change the current
release/tagging procedure in a way that a Qt4
release with a incremented patch level release
number doesn't depend on the current state of
the 4.8 branch.
