abv e7195ab476 0024023: Revamp the OCCT Handle -- handle
Macro defining Handle class is replaced by template class implementing the same concept (defined in Standard_Handle.hxx and Standard_Transient.hxx), opencascade::handle<>.

Header file Standard_DefineHandle.hxx becomes deprecated: the only useful macro DEFINE_STANDARD_RTTI is defined now in Standard_Type.hxx. Standard_DefineHandle.hxx is kept for compatibility, it defines macros previously used for definition of Handles and RTTI as empty. Macro DEFINE_STANDARD_HANDLE(C1,C2) is also kept for compatibility; now it expands to typedef "Handle_C1" to corresponding handle class.

Definitions of macro Handle() and STANDARD_TYPE() moved from Standard_Macro.hxx to Standard_Handle.hxx (new file) and Standard_Type.hxx, respectively.

New template class NCollection_Shared added, allowing to define sub-class manipulated by handle, for any non-transient class.

Adaptations for compiling with GCC 4.7
