    Initial attempt at clean vnode shutdown that waits for queued work

    Vagabond authored
    bz1188
    
    This patch adds a patched supervisor module that supports graceful
    shutdown from a simple_one_for_one, so when a node stops gracefully, we
    can block shutdown long enough to process any queued work and do any
    other cleanups.

    Made it possible to pass in the app name into register and
    avoid the module/pid application lookup.

    Changed get_counter to return 0 on missing rather than undefined.

    Only consumer I could find was in riak_kv_vnode - and that was
    wrapping vclock:get_counter with a function to do the conversion.

    Updated node watcher test to add members to the ring it builds.

    Membership is no longer derived from ownership.

    Changed vnode to always use get_my_ring.

    jonmeredith authored
    Many unit tests just set up a test ring with mochiglobal
    so they don't have to start the ring manager.  This makes
    them work again if the ring manager is down.

    Overhaul cluster membership, ring format, and gossip protocol

    Change cluster membership/gossip/ring in the following manner:
    -- Partition ownership and cluster membership are decoupled concepts.
    
    -- A single node in the cluster makes all partition claim decisions
       in a deterministic manner, avoiding endless churn possible in random
       merging. This single node (the claimant) can be assumed by any node in the
       cluster, and therefore avoids introducing a single point of failure.
    
    -- All data from all vnode modules is guaranteed to be handed off to a new
       owner before the owner takes over ownership for a partition, thus avoiding
       requests prematurely being sent to a node that does not yet have the data.
    
    -- Nodes will always handoff their data before cleaning exiting the cluster,
       even if the node is restarted before finishing handoff.
    
    -- Waiting for ring convergence is now part of the gossip/membership protocol,
       and is used to ensure consistent ring transitions across the cluster.
    
    -- Joining/leaving a cluster is handled more gracefully, and there is no
       need to wait for ring convergence (riak-admin ring-ready) as is previously
       suggested. Adding 20 nodes to a cluster at once should "just work".
    
    -- Handoff related to partition ownership changes can now occur under load,
       therefore allowing a cluster to scale up/down while handling normal
       requests.
    
    Other changes:
    -- Support for new commands: member_status, ring_status.
    -- Tracking of various new riak_core stats.
