demandimport: disable if chg is being used In chg's case, making modules lazily loaded could actually slow down things since chg pre-imports them. Therefore disable demandimport if chg is being used. This is not done by setting `HGDEMANDIMPORT` chg client-side because that has side-effects on child processes (hooks, etc). Differential Revision: https://phab.mercurial-scm.org/D351
