Change trunk from 4.2 to 5.0

– update MessagingService (remove the 4.1 version that was only a placeholder in test code bc serialisation test files were previously incorrectly serialising random UUIds for TimeUUIDs)
 – update upgrade jvm-dtests
 – remove older serialization binary files we are no longer testing against

 patch by Mick Semb Wever; reviewed by Brandon Williams for CASSANDRA-17973
