Fabian Reinartz b09d90c79c Add decoding method to retrieve unsafe strings
When decoding data from mmaped blocks, we would like to retrieve
a string backed by the mmaped region. As the underlying byte slice
never changes, this is safe.

Fabian Reinartz 6892fc6dcb Finish old WAL segment async, default to no fsync
We were still fsyncing while holding the write lock when we cut a new
segment. Given we cannot do anything but logging errors, we might just
as well complete segments asynchronously.

There's not realistic use case where one would fsync after every WAL
entry, thus make the default of a flush interval of 0 to never fsync
which is a much more likely use case.

Fabian Reinartz 5bed8af4cb retrieval: pool scrape buffers
This adds a bucketed buffer pool to the scrapers so we don't have to
allocate a new buffer on each scrape or hold it fixed to the scrape
loop.

The latter can consume significant amounts of unused memory, e.g. 4GB
when scraping 2MB /metrics from 2000 targets.

Fabian Reinartz c36d574290 Replace single head lock with granular locks
This adds various new locks to replace the single big lock on
the head. All parts now must be COW as they may be held by clients
after initial retrieval.
Series by ID and hashes are now held in a stripe lock to reduce
contention and total holding time during GC. This should reduce
starvation of readers.

Fabian Reinartz 3901b6e70b Remove multiple heads
This changes the structure to a single WAL backed by a single head
block.
Parts of the head block can be compacted. This relieves us from any head
amangement and greatly simplifies any consistency and isolation concerns
by just having a single head.
