Dieter Plaetinck	cda025b5b5	TSDB: demistify SeriesRefs and ChunkRefs (#9536) ... * TSDB: demistify seriesRefs and ChunkRefs The TSDB package contains many types of series and chunk references, all shrouded in uint types. Often the same uint value may actually mean one of different types, in non-obvious ways. This PR aims to clarify the code and help navigating to relevant docs, usage, etc much quicker. Concretely: * Use appropriately named types and document their semantics and relations. * Make multiplexing and demuxing of types explicit (on the boundaries between concrete implementations and generic interfaces). * Casting between different types should be free. None of the changes should have any impact on how the code runs.

Bryan Boreham	87d909df4a	Remove symbols map from TSDB head (#9301) ... This saves memory, effort and locking. Since every symbol is also added to postings, `Symbols()` can be implemented there instead. This now has to build a map for deduplication, but `Symbols()` is only called for compaction, and `gc()` used to rebuild the symbols map after every compaction so not an additional cost.
