* syncapi: Rename and split out tokens Previously we used the badly named `PaginationToken` which was used for both `/sync` and `/messages` requests. This quickly became confusing because named fields like `PDUPosition` meant different things depending on the token type. Instead, we now have two token types: `TopologyToken` and `StreamingToken`, both of which have fields which make more sense for their specific situations. Updated the codebase to use one or the other. `PaginationToken` still lives on as `syncToken`, an unexported type which both tokens rely on. This allows us to guarantee that the specific mappings of positions to a string remain solely under the control of the `types` package. This enables us to move high-level conceptual things like "decrement this topological token" to function calls e.g `TopologicalToken.Decrement()`. Currently broken because `/messages` seemingly used both stream and topological tokens, though I need to confirm this. * final tweaks/hacks * spurious logging * Review comments and linting
