largefiles: restore standins according to restored dirstate

Before this patch, standins are restored from the NEW parent of the
working directory at "hg rollback", and this causes:

  - standins removed in the rollback-ed revision are restored, and
    become orphan, because they are already marked as "R" in the
    restored dirstate and expected to be unlinked

  - standins added in the rollback-ed revision are left as they were
    before rollback, because they are not included in the new parent
    (this may not be so serious)

This patch replaces the "merge.update" invocation with a specific
implementation to restore standins according to restored dirstate.

This is also the preparation to centralize the logic of updating
largefiles into the function wrapping "merge.update" in the subsequent
patch.

After that patch, "merge.update" will also update largefiles in the
working directory and be redundant for restoring standins only.
