* mh-acros.el (require): Remove defadvice of require as defadvice is

verboten within Emacs and our implementation was returning the wrong
value from require. Upcoming restructuring should make this
unnecessary.
(mh-assoc-ignore-case): Replace with defsubst assoc-string.

* mh-alias.el (mh-alias-local-users, mh-alias-reload, mh-alias-expand,
mh-alias-minibuffer-confirm-address): Use it.

* mh-identity.el (mh-identity-field-handler): Use it.
