Do not crash on Symbian

The qml debugging enabler in QtDeclarative made any Qt app crash
which used QDeclarative. Reason was that QtDeclarative.dll tried
to directly access (private) writable static data from QtGui.dll.

This patch adds an accessor function for the data to QtGui, and
the crash is gone.
