    Make get_data/async/tmp_dir explicit

    functools.partial is all well and good in code, but apparently it
    doesn't play real well with docs.

    Leave less garbage in /var/tmp

    All our tests that invoked broker.set_sharding_state() created
    /var/tmp/tmp, when it called DatabaseBroker.get_device_path(),
    then added "tmp" to it. We provided 1 less level, so it walked up
    ouside of the test's temporary directory.

    The case of "cleanUp" instead of "tearDown" didn't break out of
    jail, but left trash in /var/tmp all the same.

    Rebuild frags for unmounted disks

    Change the behavior of the EC reconstructor to perform a fragment
    rebuild to a handoff node when a primary peer responds with 507 to the
    REPLICATE request.

    Each primary node in a EC ring will sync with exactly three primary
    peers, in addition to the left & right nodes we now select a third node
    from the far side of the ring. If any of these partners respond
    unmounted the reconstructor will rebuild it's fragments to a handoff
    node with the appropriate index.

    To prevent ssync (which is uninterruptible) receiving a 409 (Conflict)
    we must give the remote handoff node the correct backend_index for the
    fragments it will recieve. In the common case we will use
    determistically different handoffs for each fragment index to prevent
    multiple unmounted primary disks from forcing a single handoff node to
    hold more than one rebuilt fragment.

    Handoff nodes will continue to attempt to revert rebuilt handoff
    fragments to the appropriate primary until it is remounted or
    rebalanced. After a rebalance of EC rings (potentially removing
    unmounted/failed devices), it's most IO efficient to run in
    handoffs_only mode to avoid unnecessary rebuilds.

    Stop using duplicate dev IDs in write_fake_ring

    This would cause some weird issues where get_more_nodes() would actually
    yield out something, despite us only having two drives.

    encryption: Stop being cutesy with os.path.join()

    Turns out, we *care* about the path, and object paths *don't follow
    filesystem semantics*!

    Be explicit: /<account>/<container>/<object>

    Bump the key version number so we know whether we can trust the full path
    or not.
