cmdutil: introduce deprecated aliases

c8e2d6ed1f9e moved some objects used by Evolve and hence broke the latest
Evolve revision. Next Evolve version will use the new objects when available
but introduce deprecated aliases so users using older version of Evolve won't
have a broken Evolve extension.

Differential Revision: https://phab.mercurial-scm.org/D2023
