This patch adds support in bpy.props for getter/setter callback functions. We already have update callbacks, but generic get/set functions can come in handy in some cases where the functionality is too complex to use a single value.

The current C callback functions are too simple allow a straightforward implementation, in particular they don't receive the PropertyRNA pointer itself as an argument, which means the callback cannot directly access the PropertyRNA's py_data pointers which store the python function objects. For this reason a second runtime variant of these callbacks has been added. It is only used for runtime callbacks and not in makesrna, but otherwise works the same way.
