REVISION SUMMARY
  Currently we don't have a defined way in core to make some hidden revisions
  visible in filtered repo. Extensions to achieve the purpose of unhiding some
  hidden commits, wrap repoview.pinnedrevs() function.
  
  To make the above task simple and have well defined API, this patch adds a new
  attribute '_visibilityexceptions' to localrepository class which will contains
  the hidden revs which should be exception.
  
  This patch also adds API to add revs to the attribute set and get them.
