* Merge forward * Tidy up a bit * TODO: What to do with NextBatch here? * Replace SyncPosition with PaginationToken throughout syncapi * Fix PaginationTokens * Fix lint errors * Add a couple of missing functions into the syncapi external storage interface * Some updates based on review comments from @babolivier * Some updates based on review comments from @babolivier * argh whitespacing * Fix opentracing span * Remove dead code * Don't overshadow err (fix lint issue) * Handle extremities after inserting event into topology * Try insert event topology as ON CONFLICT DO NOTHING * Prevent OOB error in addRoomDeltaToResponse * Thwarted by gocyclo again * Fix NewPaginationTokenFromString, define unit test for it * Update pagination token test * Update sytest-whitelist * Hopefully fix some of the sync batch tokens * Remove extraneous sync position func * Revert to topology tokens in addRoomDeltaToResponse etc * Fix typo * Remove prevPDUPos as dead now that backwardTopologyPos is used instead * Fix selectEventsWithEventIDsSQL * Update sytest-blacklist * Update sytest-whitelist
