Change in wxWindow the access specifier of the wxEvtHandler event processing and queuing functions

from public to protected. Adapt wxWidgets code and wxWidgets samples to always use wxWindow::GetEventHandler()
when calling such functions on a wxWindow rather than directly using wxWindow::ProcessEvent, etc.
This enables correct event dispatching to the event handlers which have been pushed (with PushEventHandler) on the 
windows.
