Adaptations for compiling with GCC 4.7 and 4.8: - Construction semantics is used for Handle objects being initialized by const Handle objects of derived type, to avoid overload resolution error in GCC 4.7. - Missing includes added. - Fixed bugs related to misuse of direct casts of handle. - Eliminate CLang warnings on uninitialized and unused variables, functions, and expressions
