Bryan Boreham 8d350d9e0c Update package model/textparse tests for new labels.Labels type
We don't want to touch the result labels now we create them differently.

Bryan Boreham 1f04899ae3 Update package model/textparse for new labels.Labels type
Parse metrics using labels.ScratchBuilder, so we reduce assumptions about
internals of Labels.

Bryan Boreham 8120af22e2 benchmarks: SetBytes takes bytes per operation
Where the code was multiplying bytes by number of operations, this
resulted in absurdly high throughput numbers.

Also, in `BenchmarkParse()`, don't run the `expfmt` case twice.

beorn7 a7c519930e histograms: Add Compact method to the normal integer Histogram
And use the new method to call to compact Histograms during
parsing. This happens for both `Histogram` and `FloatHistogram`. In
this way, if targets decide to optimize the exposition size by merging
spans with empty buckets in between, we still get a normalized
results. It will also normalize away any valid but weird
representations like empty spans, spans with offset zero, and empty
buckets at the start or end of a span.

The implementation seemed easy at first as it just turns the
`compactBuckets` helper into a generic function (which now got its own
file). However, the integer Histograms have delta buckets instead of
absolute buckets, which had to be treated specially in the generic
`compactBuckets` function. To make sure it works, I have added plenty
of explicit tests for `Histogram` in addition to the `FloatHistogram`
tests.

I have also updated the doc comment for the `Compact` method.

Based on the insights now expressed in the doc comment, compacting
with a maxEmptyBuckets > 0 is rarely useful. Therefore, this commit
also sets the value to 0 in the two cases we were using 3 so far. We
might still want to reconsider, so I don't want to remove the
maxEmptyBuckets parameter right now.
