Setting a cancel button on QProgressDialog more than once caused the layout
to be invalid. The layout was only applied when the dialog resizes or the
style changes, but not when a new cancel button is set.
The solution is to update the layout() before showing the dialog when adopting
new child widgets.

Complete search and replace of QtTest and QtTest/QtTest with QTest, as
QtTest includes the whole module. Replace all such instances with
correct header includes. See Jira task for more discussion.

Current implementation of QProgressDialog always calls
QCoreApplication::processEvents() when the user calls
QProgressDialog::setValue() if the PD is modal. For most cases this is
fine, but when using a Qt::WindowModal PD with setValue() connected to
a signal in another thread using Qt::QueuedConnection a reentrancy
issue is present if setValue() is triggered too frequently as the
execution of its previous call may not have finished. If this happens
too many times in a row a stack overflow will occur.
Current documentation notes this potential issue but offers no way it
avoid it while still using QProgressDialog (user must implement a
custom dialog) without resorting to using Qt::BlockingQueuedConnection,
which unnecessarily reduces performance.
Introduces the boolean reentrancy guard "processingEvents" that is
checked before calling QCoreApplication::processEvents() in a modal
PD when setValue() is used. It is set before the first call to
processEvents() and cleared after that call returns. This ensures that
only one invocation of processEvents() is possible from within
setValue() at a time, and thereby minimizes iterations of the main event
loop and eliminates the aforementioned stack overflow condition.

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Outdated header.LGPL removed (use header.LGPL21 instead)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

1) everyone forgets to do so (proof: tst_qnetworkaccessmanager_and_qprogressdialog.cpp
forgot too, which led to a valgrind warning, the elapsed timer was never started)
2) setValue(0) makes no sense if the progress dialog goes from 50 to 60,
or any other non-zero minimum value.
Fixed by starting the timer in the constructor (most code doesn't reuse
progress dialogs, so this fixes the most common case), and by also starting
the timer when calling setValue(minimum()) for well-behaved dialogs.
setValue(0) special case kept for compatibility.

It is documented to be, and the LanguageChange event is caught and processed.
However, retranslateStrings() uses QProgressDialog::setCancelButtonText(),
which unconditionally sets useDefaultCancelText=true, blocking any further
changes to the button text by subsequent LanguageChange events.
The fix is to use extracted QProgressDialogPrivate::setCancelButtonText()
which - quite intentionally - doesn't set useDefaultCancelText.
