Start a new WAL segement on head truncation. (#605) 
This reduces disk space usage to not be a minimum of 3 128MB files
in small setups. This will possibly also help debug wal data issues,
by making things a bit more deterministic.

Simplify mergedPostings.Seek (#595) 
The current implementation leads to very slow behaviour when there's
many lists, this no worse than n log k, where k is the number of posting
lists.

Adjust benchmark to catch this.

Remove flattening of without lists, not needed anymore.

Benchmark versus 0.4.0 (used in Prometheus 2.7):

Correctly handle empty labels. (#594) 
Currently a time series with empty labels is not treated the same
as one with missing labels. Currently this can only come from
ALERTS&ALERT_FOR_STATE so it's unlikely anyone has actually hit it.

Be smarter in how we look at matchers. (#572) 
* Add unittests for PostingsForMatcher.

* Selector methods are all stateless, don't need a reference.

* Be smarter in how we look at matchers.

Look at all matchers to see if a label can be empty.

Optimise Not handling, so i!="2" is a simple lookup
rather than an inverse postings list.

All all the Withouts together, rather than
having to subtract each from all postings.

Change the pre-expand the postings logic to always do it before doing a
Without only. Don't do that if it's already a list.

The initial goal here was that the oft-seen pattern
i=~"something.+",i!="foo",i!="bar" becomes more efficient.
