Ævar Arnfjörð Bjarmason 9b1cdd334d transport: rename "fetch" in transport_vtable to "fetch_refs"
Rename the "fetch" member of the transport_vtable to "fetch_refs" for
consistency with the existing "push_refs". Neither of them just push
"refs" but refs and objects, but having the two match makes the code
more readable than having it be inconsistent, especially since
"fetch_refs" is a lot easier to grep for than "fetch".
