Fix KHR_Debug segfault errors Calls to functions ObjectLabel, ObjectPtrLabel, GetObjectLabel, GetObjectPtrLabel were resulting into segfaults due to improper validation and parameter handling. It could be that the implementations of those functions were based on an earlier version of the KHR_Debug extension. The patch fixes the segfault error and almost all failing dEQP 3.1 tests related to KHR_Debug. The failing tests were also relevant to older ES versions. There is still one failing test, but that one fails since ES3.1 is not fully supported yet. List of reasons for the segfault error and failing tests: - the segfault error was caused by strlen called on a null pointer - another segfault was caused by writing out the length to a null pointer - even if the buffer size for getObject(Ptr)Label is 0, still the length of the label can be returned. That was not handled.
