Couple 'o CUnit Integration Tests

[hazen]

• Ported all tests from CppUTest back to CUnit to keep things 99.44% pure
• Tested build on OSX 10.9.2 and Ubuntu 13.10
• Fixed how CUnit was reporting its errors back to make
• Fixed a riak_binary test
• Added integration tests for ping, server info, list keys and list buckets
• Other messages to follow in subsequent PRs

Those are all debug messages for multi-theading. I debated keeping them in. I guess I could #ifdef them out and only use them for debug builds.

Seg fault reproducible if you have security enabled in Riak: riak-admin security enable

[bookshelfdave]

tests pass without security enabled, which is outside the scope of this PR:
