hg: have `updatetotally` more thoroughly check updatecheck argument (API)

.. api::

    `mercurial.hg.updatetotally` is now more thorough about checking
    its `updatecheck` keyword argument. Previously invalid values
    would have used the configured default updatecheck method, but now
    will raise ValueError.
