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 5cf2662074 Refactor WAL into Head and misc improvements 2017-09-01 11:50:58 +02:00
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.
