We'd like to collect better statistics about where the time is spent in
fetches and pushes so that we can hopefully identify some areas for
future optimization. So let's add some trace2 regions around some of the
fetch/push phases so we can break down their timing.
Changes since V1:
* Use the repository struct argument in transport_push(), rather than
the global the_repository.
