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.

`if ds[i].meta.MinTime < t0 || ds[i].meta.MaxTime > t0+tr `, ds[i].meta.MinTime is always larger or equal to t0, so no need for this check.
`ulid.Parse` only checks if the length is 26. So changed to  using `ulid.ParseStrict` to also check the validity of ulid.
