lfs: access revlog directly
LFS is monkeypatching filelog.filelog and is then accessing
various filelog attributes in the monkeypatched function. This is all
fine.
But some of the attributes being accessed by LFS are revlog centric
and shouldn't be exposed on the file storage interface.
This commit changes the monkeypatched functions to access proxied
attributes on self._revlog instead of self.
This should be safe to do because non-revlog repositories should not
be using filelog instances: instead they should have a separate class
to represent file storage. So it is reasonable for LFS to assume the
_revlog attribute exists and points to a revlog.
