It's annoying when other people move something around in the Sage library
and it's no longer available in the previous location to be imported.
Sage currently has some mechanisms for alleviating this problem
(`sage.misc.superceded.deprecated_callable_import` and
`sage.structure.sage_object.register_unpickle_override` for example).
This ticket adds another option: lazily import the old name so that a
deprecation warning is issued whenever it is referred to.
