avg_over_time would produce +Inf count/sum and NaN zero bucket when
averaging a single histogram, because the count variable was initialized
to 0 instead of 1. This caused a division by zero at the end of the
function.

The float version of avg_over_time already correctly initializes count
to 1, this change makes the histogram version consistent with that.

Parser configuration is now per-engine/API/loader and no longer uses package-level flags, so behavior is consistent and tests don't rely on save/restore of global variables.

With native histograms being a stable feature, we should get rid of
this special line, which isn't really mapping maintainership to a
subtree, but to something that is all over the codebase.

Additionally, @beorn7 will soon retire from the project, so we needed
to remove him from this file anyway.
