attaching basically the same patch as yesterday -- just updated to account for a few conflicts & test-tweaks needed because of the SOLR-12326 changes.

> while simple {{type:range}} facets don't benefit from refinement, because every shard returns the same set of buckets, some bugs currently exist when a range facet contains sub facets that use refinement:
> # the optional {{other}} buckets (before/after/between) are not considered during refinement
> # when using the {{include}} option: if {{edge}} is specified, then the refinement of all range buckets mistakenly includes the lower bound of the range, regardless of whether {{lower}} was specified.
> ----
> #1 occurs because {{FacetRangeMerger extends FacetRequestSortedMerger<FacetRange>}} ... however {{FacetRangeMerger}} does not override {{getRefinement(...)}} which means only {{FacetRequestSortedMerger.buckets}} is evaluated and considered for refinement. The additional, special purpose, {{FacetBucket}} instances tracked in {{FacetRangeMerger}} are never considered for refinement.
> #2 exists because of a mistaken in the implementation of {{refineBucket}} and how it computes the {{start}} value.
