A new API is available for AddEventHandlers, to get errors but also be
able to cancel handlers.
Doing the easy thing for the release, which is just to log errors.
We could see how to improve this in the future to handle the errors
properly and cancel the handlers.

We have 2 bugfixes, one which is important for Windows users and
another one on native histograms. I think it is worth cutting another
bugfix release before 2.41 comes out.

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.

Typical parameters are one hour by 1 minute step, where the
function would allocate a slice of 3.6 million samples instead of 60.

* Switch from 'sanity' to more inclusive lanuage
"Removing ableist language in code is important; it helps to create and
maintain an environment that welcomes all developers of all backgrounds,
while emphasizing that we as developers select the most articulate,
precise, descriptive language we can rather than relying on metaphors.
The phrase sanity check is ableist, and unnecessarily references mental
health in our code bases. It denotes that people with mental illnesses
are inferior, wrong, or incorrect, and the phrase sanity continues to be
used by employers and other individuals to discriminate against these
people."

For performance reasons we may use a different implementation of Hash()
in future, so note this so callers can be warned.
