scmutil: allowing different files to be prefetched per revision

The old API takes a list of revision separate from the file matcher, and thus
provides no way to fetch different sets of files from each revision. In
preparation for adding one such usage, I'm changing the API to take a list of
(revision, file matcher) tuples instead.
