Extend Bug 5675 fix to include case where partition runs from a split-flow.  Change magic format of "subjob instance id" to always start with the top-level job instance id as "prefix".
Minor cleanup of updateStepExecution()
Fixed jbatch as hard-coded schema (by accident) and removed duplicate query altogether
Go back to item-count based on items read (See Bug 6509). Increment rollback metric by one even for 'normal' rollback (i.e. not a retry-with-rollback scenario). Clean up use of CheckpointAlgorithm
