beorn7 5f366e9b62 histograms: Improve tests and fix exposed bugs 
This adds negative buckets and access of float histograms to
TestHistogramChunkSameBuckets and TestHistogramChunkBucketChanges.

It also exercises a specific pattern of reusing an iterator (one where
no access has happened).

This exposes two bugs (where entries for positive buckets where used
where the corresponding entries for negative buckets should have been
used). One was fixed in #11627 (not merged), which triggered the work
in this commit.

This commit fixes both issues, so #11627 can be closed.

It also simplifies the code in the histogramIterator.Next method that
aims to recycle existing slice capacity.

Furthermore, this is on top of the release-2.40 branch because we
should probably cut a bugfix release for this.

scrape: Fix accept header, now for real (#11552) 
This reinstates the behavior of v2.39. The header got messed up in the
sparsehistogram when the change of the version in main was merged into
it (and the merge conflict had to be resolved).

I don't think the current state will actually break anyone, although
it is technically possible. I propose to merge this into the bugfix
branch in any case, but I think we can wait for other bugfixes before
cutting a v2.40.1. (Unless, of course, somebody reports an actual
breakage because of the header.)

scrape: Fix accept header (#11542) 
First of all, there was a typo: `encoding=delimited` was a left-over
in the `scrapeAcceptHeader`.

Second, the recently updated `version=1.0.0` prevents current versions
of client_golang to negotiate OpenMetrics, as they expect
`version=0.0.1` or no version at all. This commit adds, with lower
priority, the latter (no version at all) to the accept header.

Fixes #11540,

chunkenc: Slightly optimize xorWrite/xoRead (#11476) 
With these changes, the "happy path" when the leading and trailing
number of bits don't need an update, fewer operations are needed.

The change is probably very marginal (no change in the benchmark added
here, but the benchmark also doesn't cover non-changing values), and
an argument could me made that avoiding pointers also has its
benefits.

However, I think that reducing the number of return values improves
readability. Which convinced me that I should at least propose this.
