Callum Styan a971f52ac8 clean up after running repair tests (#372) 
implement a `CopyDirs` helper to walk all dirs and subdirs and copy all files within to a destination folder.

Refactor `TestRepairBadIndexVersion` to use the `CopyDirs` so it works on a copy db and remove the copy after the test.
This allows running the test more than once and doesn't confuse git.

Fabian Reinartz d951140ab8 wal: avoid heap allocation in WAL reader 
The buffers we allocated were escaping to the heap, resulting in large
memory usage spikes during startup and checkpointing in Prometheus.
This attaches the buffer to the reader object to prevent this.

Fabian Reinartz 7841d417b3 Ensure blocks are time-ordered in memory

A regression caused us to hold them ordered by ULID, i.e. by creation
