ChunkVersion assumes little-endian byte order

      The _minor and _major fields in ChunkVersion are unioned with a 64-bit _combined field, which are used for fast reads/writes and comparisons in little-endian order. This doesn't work on big-endian systems and causes failures in ChunkManagerTests that can be worked around by providing slower but portable versions of the accessor methods and comparison operators when MONGO_CONFIG_BYTE_ORDER == 4321.
