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.

'''browse command output with an external pager (DEPRECATED)
Forcibly enable paging for individual commands that don't typically
request pagination with the attend-<command> option. This setting
takes precedence over ignore options and defaults::
