pytalloc: fixed py_talloc_steal()
py_talloc_steal() was implemented as a macro which evaluated it's 2nd argument twice. It was often called via a macro with a 2nd argument that was a function call, for example an allocation in py_talloc_new(). This meant it allocated memory twice, and leaked one of them. This re-implements py_talloc_steal() as a function, so that it only does the allocation once.
