merge: replace magic strings with NAMED_CONSTANTS (API)

.. api::

    `mercurial.hg.update*` and `mercurial.merge.update` now expect a value
    from a set of NAMED_CONSTANTS (`merge.UPDATECHECK_*` constants)
    rather than a collection of magic strings. As of now, the values
    are the same, but code should be prepared for these values to
    change in the future.
