Fix crash related to multiple inheritance
In the <class>_PTR_CppToPython_<class> converter function (written by CppGenerator::writeConverterFunctions()), the generated code used typeid(*ptr).name() to retrieve the name to use for the SbkObjectTypes. This construct returns the name of the outermost class (for example, "QWidget" for a QWidget-type paint device returned by QPainter::device()), as opposed to "QPaintDevice *" returned by typeid(ptr).name(). This caused a crash with multiple inheritance since QWidget inherits QObject and QPaintDevice and the "QWidget" type was associated with the QPaintDevice pointer. To fix this: - Add API to libshiboken to obtain the SbkObjectType* by name and check for the presence of a special cast function (multiple inheritance). - Generate the code of <class>_PTR_CppToPython_<class> as follows: Check whether the outermost type obtained by typeid(*ptr).name() has a special cast function. If that is the case, use the type name obtained by typeid(ptr).name() (base class) to create the wrapper.
