Patch to use XXHash algorithm. Brunt of the algorithm was implemented by

> Currently we are using murmur hash algorithm for performing hash operations.
> We would like to move to XXHash which is a fast non-cryptographic hash
> algorithm. More information can be found here:
> https://code.google.com/p/xxhash/
> The implementation should also eliminates an extra copy of the ByteBuf to be
> consumed by the hash function.
