Port the Murmur hash functions from Java to C++. This is ironic, because these functions actually originated in C code, which the Cassandra guys converted to Java :-) The Murmur hash is used in Cassandra for several things, including the bloom filter (which is part of each sstable), and the default data partitioner (Murmur3Partitioner). I tested on some example string that all three methods (hash32, hash2_64 and hash3_x64_128) produce exactly the same output in the new C++ code as they do in the original Java functions. This is important, because we want the C++ node to be able to run alongside Java nodes, so they have to agree on the same hash function.
