shiboken: Fix race condition with unprotected Py_INCREFs
The signalmanager module contains a PyObjectWrapper object
into which PySide::SignalManager::qt_metacall calls via many
hard-to-track indirections.
Finding this problem was quite tricky. It was done by modifying
the Py_INCREF and Py_DECREF macros of a debug Python
interpreter and using the new PyGILState_Check function to
provoke a crash if the GIL was not held.
See the online documentation for details.
