d815e6adfd Changes to CreateObject() now returns back md5 along with any error 
- This change is necessary to avoid the racy calls to GetObjectMetadata()
- This change is also necessary since one has to reply back md5sum with
  PUT object response header

f8a16dd22b Memory now evicts bucket if no more objects in memory struct 
- To avoid race in expiration while accessing memory driver structs with
  in two competing write locks. Use lru Len() instead to know exact length
  to schedule for eviction.

- squash both bucket and object structs, instead use a separate map to keep
  mutable info of lastAccessTime which can be independently used inside the
  expiration routine.
