lfs: infer the blob store URL from an explicit pull source

I don't see any easier way to do this because the update part of `hg pull -u`
happens outside exchange.pull(), and commands.postincoming() doesn't take a
path.  So (ab)use the mechanism used by subrepos to redirect where subrepos are
pulled from when an explicit path is given.  As a bonus, this should allow lfs
blobs to be pulled into a subrepo when it is checked out.

An explicit push path can be handled within exchange.push().  That can be done
next, outside of this dirty hack.

# Dummy extension to define a namespace containing revision names

def reposetup(ui, repo):
    names = {b'r%d' % rev: repo[rev].node() for rev in repo}
    namemap = lambda r, name: names.get(name)
    nodemap = lambda r, node: [b'r%d' % repo[node].rev()]

    ns = namespaces.namespace(b'revnames', templatename=b'revname',
                              logname=b'revname',
                              listnames=lambda r: names.keys(),
                              namemap=namemap, nodemap=nodemap)
    repo.names.addnamespace(ns)
