scmutil: introduce deprecated alias for revpair()

revsingle() returns a context object, revpair() returns nodeids,
revrange() returns integer revisions (in a revset). I'm going to
reduce this inconsistency by making revpair() return context
objects. Changing the return type is not nice to extensions, so this
patch introduces a nodeid-returning version of revpair() that they can
detect and use. Update callers to the new function so we can change
revpair() itself and then migrate them back one by one.
