Fix panic, out of order chunks, and race warning during WAL replay (#9856) 
* Fix panic on WAL replay

Signed-off-by: Ganesh Vernekar <ganeshvern@gmail.com>

* Refactor: introduce walSubsetProcessor

walSubsetProcessor packages up the `processWALSamples()` function and
its input and output channels, helping to clarify how these things
relate.

* Refactor: extract more methods onto walSubsetProcessor

This makes the main logic easier to follow.

* Fix race warning by locking processWALSamples

Although we have waited for the processor to finish, we still get a
warning from the race detector because it doesn't know how the different
parts relate.

Add a lock round each batch of samples, so the race detector can see
that we never access series owned by the processor outside of a lock.

TSDB

GoPkg

This directory contains the Prometheus TSDB (Time Series DataBase) library, which handles storage and querying of all Prometheus v2 data.

Due to an issue with versioning, the "latest" docs shown on Godoc are outdated. Instead you may use the docs for v2.31.1
