* Push the matchers for LabelNames all the way into the index.
NB This doesn't actually implement it in the index, just plumbs it through for now...

* Revert changes I don't understand
Can't see why do we need to hold a mutex on symbols, and the purpose of
the LabelNamesFor method.
Maybe I'll need to re-add this later.

* Implement LabelNamesFor
This method provides the label names that appear in the postings
provided. We do that deeper than the label values because we know
beforehand that most of the label names we'll be the same across
different postings, and we don't want to go down an up looking up the
same symbols for all different series.

However, I still don't understand why do we need a mutex here.

I still don't see why we need to grab that unrelated mutex, but at least
now we're grabbing it consistently

I did not want to move those in previous PR to make it easier to review. Now small cleanup time for readability. (:
## Changes
* Merge series goes to `storage/merge.go` leaving `fanout.go` for just fanout code.

* Unskiped one test: TestFanout_SelectSorted/chunk_querier
* Moved block series set codes responsible for querying blocks to `querier.go` from `compact.go`
