filelog: stop proxying deltaparent() (API)
deltaparent() obtains the revision number of the base revision a
delta in storage is stored against. It is highly revlog-centric and
may not apply to other storage backends. As a result, it doesn't
belong on the generic file storage interface.
This method/proxy is no longer used in core. The last consumer was
probably changegroup code and went away with the transition to
emitrevisions().
