waitTurn now checks the context before taking a host's slot, so a request canceled before Fetch takes none. The request let through takes the slot and gets a release; limitedTransport calls it when the round trip fails before the request headers are written (traced with httptrace), restoring the host's previous send time and waking requests waiting for their turn. Adds TestFetchUnsentRequestHoldsNoSlot (canceled before Fetch and failed dial on a host with no previous request; the next request does not wait) and TestReleaseWakesWaiter.
