repoview: add a new filtername for accessing hidden commits
This patch adds a new filter 'visible-hidden' for repository and will be used to
return a repo object with user passed revisions unhidden. Unlike the
directaccess extension in fb-hgext and previous series adding the functionality,
this time we introduce only one new filter as whether to warn user or not is
handled by scmutil.unhidehashlikerevs().
