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 78780cd2ba Segment chunk file
This adds write path support for segmented chunk data files.
Files of 512MB are pre-allocated and written to. If the file size
is exceeded, the next file is started. On completion, files
are truncated to their final size.

Fabian Reinartz f734773214 Replace per-file locking with single PID lock file
File locks have a multitude of problems that make them hard to use
correctly. As they are just advisory, they are only meaningful to
prevent accidents like running the same process twice.
A simple PID file lock works reliably in those cases and is simpler.

Fabian Reinartz 30efe4a58c Support writing to multiple head blocks
This is an initial (and hacky) first pass on allowing
appending to multiple blocks simultaniously to avoid
dropping samples right after cutting a new head block.
It's also required for cases like the PGW, where a scrape may
contain varying timestamps.
