Review request for giraph.


Summary (updated)
-------

refactoring that gives BasicVertex this 3 new methods:

    public abstract Iterable<M> getMessages()

returns an unmodifiable iterable allowing access to the current messages

    public abstract void setMessages(Iterable<M> messages);

replacement for getMsgList().clear() followed by getMsgList().addAll(...);

    public abstract void releaseResources();

after a vertex voted to halt, all references to messages it could still hold should be removed
to enable earlier GC, instead of externally calling replacement for getMsgList().clear(),
this method should be used

Local unit tests pass, unfortunately I wasn't yet able to run the tests on my hadoop cluster
(still have problems because I can only access it via a socks proxy)


This addresses bug GIRAPH-80.
