Introduce \newoperator 

\newoperator mimics amsamth's \DeclareMathOperator; that is, it
defines a macro for an operator name which is consistent with the
standard operators like \max, \lim, and \lim w.r.t. appearance and
behavior.

The star variant \newoperator* permits the operator to take limits
like \max and \lim (e.g. \lim_{x\rightarrow\infty}) instead of a
subscript.
