*                        Important Behavior Changes                        *
****************************************************************************

 - [QTBUG-57602] Introduce an extension interface for the virtual keyboard.
   All the current input methods and some special keyboard layouts (e.g.
   Hunspell, OpenWnn, etc.) have been moved to extensions. The extension
   interface allows third party to create a new input method without having
   to modify or rebuild the virtual keyboard. In addition, this change
   makes it possible to add features and languages independently by copying
   the desired extension to the system.
 - [QTBUG-57602] Introduce a virtualkeyboard module, which can be linked
   against an extension plugin. This module provides the C++ API necessary
   for creating an input method.
 - [QTBUG-57602] Wrap the entire virtual keyboard API into Qt namespace
   (e.g. QT_BEGIN_NAMESPACE/QT_END_NAMESPACE).
