8f61d6b6be Move memory code out, add it as layer on top of existing donut code
Just like how http.Handlers can be overlayed on top of each other
with each implementing ServeHTTP().

drivers.Driver can be overlayed on top of each other in similar manner
which would implement the drivers.Driver interface.

ac4d8fe478 Add free() method for proxyReader to aggressively de-allocate Read data, to handle certain out of memory conditions
There are still some more out there

05f8654e3d Add Append() method to trove cache for appending data to an existing key
This largely avoids a large buffer copy which would accumulate inside proxyReader{}

This patch also implements "initialize()" function to init and populate data
on all the existing buckets, avoiding the redundant ListBuckets() invoked by
every API call.

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
