[SYSTEMDS-2581] Serialization, deserialization of dedup DAGs

This patch includes:
 - a new approach to hook the dedup patches to the main trace.
   Now the dedup opcode also encodes details needed for mapping
   the item back to the correct dedup patch after deserialization.
 - Two methods to serialize and deserialize the compressed dedup
   DAGs. Serialization logic merges all the patches in a single
   string and maintains headers with all the information.
   Deserialization logic parses the headers to map the DAGs to
   the right dedup entries from the main trace.
