* Enable MATCHED and UNMATCHED mode for index prefetch
MATCHED mode returns index entries whose secondary KVs are present,
UNMATCHED mode returns index entries whose secondary KVs are absent.
Note that the conflict read range of this txn is set in 2 steps:
* Set the conflict range for primary query according to request
* Set the conflict ranges for secondary queries according to responses.
As a result, conflicts of different match_index mode are taken care of.
* Fix c binding
* Fixing leaked stream with explicit notify failed before destructor
* better logic to prevent races in change feed fetching
* Found new race that makes assert incorrect
* handle server overloaded in initial read from fdb
* Handling more blob error types in granule retry
* Fixing rollback metadata problem, added better debugging
* Fixing version race when fetching change feed metadata
* Better racing split request handling
* fixing assert
* Handle change feed popped check in the blob worker
* fix: do not use a RYW transaction for a versionstamp because of randomize API version (#6768)
* more merge conflict issues
* Change feed destroy fixes
* Fixing change feed destroy and move race
* Check error condition in BG file req
* Using relative endpoints for blob worker interface
* Fixing bug in previous fix
* More destroy and move race fixes
* Don't update empty version on destroy in case it gets rolled back. moved() and removing will take care of ensuring it is not read
* Bug fix (#6796)
* fix: do not use a RYW transaction for a versionstamp because of randomize API version
* fix: if the initialSnapshotVersion was pruned, granule history was incorrect
* added a way to compress null bytes in printable()
* Fixing durability issue with moving and destroying change feeds
* Adding fix for not fully deleting files for a granule that child granules need to re-snapshot
* More destroy and move races
* Fixing change feed destroy and pop races
* Renaming bg prune to purge, and adding a C api and unit test for it
* more cleanup
* review comments
* Observability for granule purging
* better handling for change feed not registered
* Fixed purging bugs (#6815)
* fix: do not use a RYW transaction for a versionstamp because of randomize API version
* fix: if the initialSnapshotVersion was pruned, granule history was incorrect
* added a way to compress null bytes in printable()
