storageutil: extract copy metadata retrieval out of filelog
As part of implementing an alternate storage backend, I found myself
reinventing this wheel.
Let's create a utility function for doing the work.

====================================
Testing head checking code: Case B-1
====================================
Mercurial checks for the introduction of new heads on push. Evolution comes
into play to detect if existing branches on the server are being replaced by
some of the new one we push.
This case is part of a series of tests checking this behavior.
Category B: simple case involving pruned changesets
TestCase 1: single pruned changeset
.. old-state:
..
.. * 1 changeset branch
