The validator classes have their definition in a header located in mutation/, while their implementation is located in a .cc in readers/mutation_reader.cc. This patch fixes this inconsistency by moving the implementation into mutation/mutation_fragment_stream_validator.cc. The only change is that the validator code gets a new logger instance (but the logger variable itself is left unchanged for now).
