e5ce2bef43 Add explicit error to Querier.Select
This has been a frequent source of debugging pain since errors are
potentially delayed to a much later point. They bubble up in an
unrelated execution path.

1dad3370fd Close WAL when closing the DB
Also, the `wal` field of the `DB` was not used anywhere, so this removes
it.

82796db37b Ensure near-empty chunks end at correct boundary
We were determining a chunk's end time once it was one quarter full to
compute it so all chunks have uniform number of samples.
This accidentally skipped the case where series started near the end of
a chunk range/block and never reached that threshold. As a result they
got persisted but were continued across the range.

This resulted in corrupted persisted data.

fb9da52b11 Add more verbose error handling for closing, reduce locking
This commit introduces error returns in various places and is explicit
about closing persisted blocks.
{Index,Chunk,Tombstone}Readers are more consistent about their Close()
method. Whenever a reader is retrieved, the corresponding close method
must eventually be called. We use this to track pending readers against
persisted blocks.

Querier's against the DB no longer hold a read lock for their entire
lifecycle. This avoids long running queriers to starve new ones when we
have to acquire a write lock when reloading blocks.

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.

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.

bceb5c1b16 When checking for amended points, do it in terms of bits.
NaN != NaN, so the previous code would incorrectly report
it as changed.

There's also plans to take advantage of the NaN payload,
so look at the entire value.

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.
