[PATCH v3 07/27] revisions API users: add straightforward release_revisions()

["Ævar Arnfjörð Bjarmason" <avarab@gmail.com>]

Add a release_revisions() to various users of "struct rev_list" in
those straightforward cases where we only need to add the
release_revisions() call to the end of a block, and don't need to
e.g. refactor anything to use a "goto cleanup" pattern.
