Tests for push passes, downloads, OPML round trips and directory refresh

Each against a local stand-in server: Apple's push service answering per token, a feed host
serving a login page and a torrent, a directory refresh of feeds that cannot be read. push.rs
takes the APNs address as a parameter so the test can point it at the stand-in. coverage.sh asks
for 8 GB free, not 9: its container is capped at 6.
