Fixes to replication job status handling:

- success, error and cancelled states now correctly reported
- source and target reports now correctly provided for each of above

Changes:
- deprecated TransferService interface, replaced by TransferService2
  - introduces new sync transfer methods
  - new TransferServiceImpl2 class, old TransferServiceImpl delegates to new class
- sync transfer now returns TransferEndEvent
- sync transfer now raises TransferFailureException
- success, error and cancelled events are now end events (raised after report events)
- transfer client handling refactored to support cancel and errors appropriately
  - converted to event loop with polling of server status for all states
  - cancel request may now end with success or error (depending on when cancel requested)
  - extract transfer errors from server
  - only raise exception for errors (cancelled now returns)
  - source and destination reports written for all states
- Added TransferEndEvent interface for end events - reports attached to end event
- replication service fixed to record source and dest reports in error case
- action service fixed to record cancelled state
