Fabian Reinartz 9c93f8f2aa Fix various races 
This fixes different race condition encoutnered when running Prometheus.
It reduces the overall performance in the synthetic benchmark a fair bit
but has no indiciations of impacting a real-world setup notably.

Fabian Reinartz 2c999836fb Add Queryable interface to Block 
This adds the Queryable interface to the Block interface. Head and
persisted blocks now implement their own Querier() method and thus
isolate customization (e.g. remapPostings) more cleanly.

Fabian Reinartz 11be2cc585 Add composed Block interfaces, remove head generation 
This adds more lower-leve interfaces which are used to compose
to different Block interfaces.
The DB only uses interfaces instead of explicit persistedBlock and
headBlock. The headBlock generation property is dropped as the use-case
can be implemented using block sequence numbers.

Fabian Reinartz 4962175218 Fix deadlock between heads and headmtx 
With hundreds of concurrent appenders the locking order between the
headBlocks on instantiating appenders and write locking the headmtx
is hard to impossible to get consistent.
Just never instantiate appenders while holding the headmtx lock in any
way.

Fabian Reinartz 34efe4e2c8 Drop position mapper from head block 
The position mapper was intended to pre-computed "expensive" ordering
of label sets. It was expensive to update and caused a lot of trouble.
Skipping this optimization entirely actually revelead it was pointless
and even harmful from the e2e perspective.

Fabian Reinartz ad5812d83a Handle WAL corruption by truncating 
This adds handling for various corruption scenarios of the WAL.
If corruption is encountered, we truncate the WAL after the last valid
entry transparently and continue appending after the offset.

Fabian Reinartz a8e8903350 Use ChunkMeta references for clarity 
This has been a common source of hard to debug issues. Its a premature
and unbenchmarked optimization and semantically, we want ChunkMetas to
be references in all changed cases.

Fabian Reinartz cb4dde7659 Fix WAL log recovery bug 
This fixes a bug where the last WAL file was closed after consuming it
instead of being left open for further writes.
Reloading of blocks on startup considers loading head blocks now.

Fabian Reinartz 2841499212 Simplify and split up iterators 
This simplifies some of the iterators by loading chunks from the
ChunkReader earlier, filtering of chunks vs filtering or series is
split into separate iterators for easier testing

Fabian Reinartz 55a9b5428a Add separate head mutex 
Introduce a seperate mutex for the head blocks to avoid a race where
a post-compaction reload may run between switching the DB's base mutex
to create a new head block in an appender.
