[tablet] a small cleanup on DeltaTracker and around
I was briefly looking at the compaction-related code and noticed a bit
of room for improvement. This patch is the result. It introduces
a bunch of minor changes to DeltaTracker and compaction-related code:
* updated DeltaTracker::Update() to accept nullptr for the
OperationResultPB output parameter
* removed per-block heap allocated instance of OperationResultPB
in ReupdateMissedDeltas()
* switched to std::atomic<bool> instead of AtomicBool for the
DeltaTracker::dms_exists_ field
* renamed delta_tracker() --> mutable_delta_tracker() for DiskRowSet
* introduced DiskRowSet::delta_tracker() to return const reference
(this is going to be used in a follow-up patch)
* updated RowSetMetadata::Commit{Redo,Undo}DeltaDataBlock() to
return 'void' instead of 'Status'
* added a few DCHECK macros to spot inconsistencies
* updated related code to be more style-compliant
