89f7a2759c Deliver Quit event when calling QCoreApplication::quit()
Instead of QCoreApplication::quit() directly calling exit(0), which would
leave QGuiApplication and client code out of the loop, we now send the
Quit event, and let it pass through event delivery, before finally ending
up in QCoreApplication::event(), where we call exit(0).

This has the advantage that QGuiApplication can ensure all windows are
closed before quitting, and if any of those windows ignore the close
event the quit will be aborted. This aligns the behavior of synthetic
quits via QCoreApplication::quit() with spontaneous quits from the
platform via QGuiApplicationPrivate::processApplicationTermination.

Clients who wish to exit the application without any event delivery or
potential user interaction can call the lower level exit() function
directly.

[ChangeLog][QtGui] Application termination via qApp->quit() will now
deliver Quit events to the application, which in turn will result in
application windows being closed as part of the application quit,
with an option to cancel the application quit by ignoring the close
event. Clients who explicitly want to exit the application without
any user interaction should call QCoreApplication::exit() explicitly.

9cc040a806 Prepare for deprecating the QDesktopWidget
QDesktopWidget is marked as obsolete in docs, but it is not yet
completely deprecated, some of its methods are still in use.

Replace uses of the following methods marked as obsolete:
- QDesktopWidget::screenNumber(QWidget*) -> QWidget::screen()
- QDesktopWidget::screenGeometry(QWidget*) -> QWidget::screen()->geometry()
- QDesktopWidget::availableGeometry(QWidget*) -> QWidget::screen()->availableGeometry()

ad4d25589f Add recent file handling to SDI/MDI and remove the recentfiles example.
The existing recentfiles example was basically a clone of the SDI
example with a "Recent" menu added. Assuming it is better to have
it all in one place, the functionality is merged into the existing
SDI/MDI examples.

- Implement recently opened files handling using a submenu and a
  QSettings array in the SDI/MDI examples.
- Remove recentfiles example.

bdbd26a3b7 Polish the widgets/mainwindows/mdi example.
- Introduce Qt 5 signals & slot syntax and remove the QSignalMapper
  used to map the triggered() signals of the per-MDI-child actions
  of the window menu to the activation slot by a functor to demonstrate
  the flexibility of the new connection syntax (the functor can
  in turn be replaced by a lambda expression once we have C++ 11).
- Merge MainWindow::createMenus()/createQToolBars()
  into MainWindow::createActions(), removing the need
  to store the actions as member variables.
  Use QMenu::addAction() for brevity.
- Use QIcon::fromTheme() to obtain system icons and use
  resource icons as fallback.
- Rewrite settings code to use
  QWidget::saveGeometry(), Widget::restoreGeometry() since
  saving size and position does not work well with multiple
  screens. Query the available size when determining
  the initial size instead of using hard-coded values
  for High-DPI screens.
- Fix minor issues in code, use multi-argument version
  of QString::arg(), QDir::toNativeSeparators() to
  present file paths to the user and static method invocation.

83a5694dc2 Update copyright headers
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
