Add GET message integration test

[hazen]

• Make unit testing write more complete test objects
• Make the number of buckets/keys in dummy object configurable to optimize testing time
• Add several helper functions like comparing binaries and objects
• Improve error reporting in testing async callbacks
• Clean up all outstanding memory leaks in current integration tests (but not unit tests)

Seems to work fine for me on OSX 10.9.2 and Ubuntu 12.04:

Which version of Riak are you testing against? I'm using Riak 1.4.7
