revlog: allow flag processors to be applied via store options This allows flag processors to be registered to specific repos in an extension by wrapping localrepo.resolverevlogstorevfsoptions(). I wanted to add the processors via a function on localrepo, but some of the places where the processors are globally registered don't have a repository available. This makes targeting specific repos in the wrapper awkward, but still manageable.
