	Value: operator=(): Check for identical instance.

	* libgda/libgdamm/value.cc: This is generally a good idea in operator=()
	implementations.

	Value: operator=(): Check for the identical underlying GValue.

	* libgda/libgdamm/value.cc: Otherwise we unset the gobject, which 
	unsets the src, because it is the same gobject, and then we reject that
	src as invalid.

	Value::set_binary(): reinit the type.

	* libgda/libgdamm/value.cc: Call value_reinit(), as we do in other set()
	methods.
