Clean up assoc_array library
Nils Ollrogge reported a bug in the assoc_array library and had a patch to fix it too, but that code was too obscure for me to follow, so I did what I preach: use modern LLM tools to help make sense of it all. So this is an LLM-assisted branch which makes the code more readable by splitting up some of the larger and hard-to-read functions. The code was then run through a test harness in user space, which not only confirmed the bug Nils reported, but found three other bugs too - all going back to the very first commit adding this library back in 2013. v2: David Howells asked for a fix-up of a couple of comments and rename assoc_array_segment_leaves() to assoc_array_fill_segment_cache(), and added his Tested-by: and Reviewed-by:
