The *NSYNC linked list API is good enough that it deserves to be part of the C libray, so this change writes an improved version of it which uses that offsetof() trick from the Linux Kernel. We vendor all of the *NSYNC tests in third_party which helped confirm the needed refactoring is safe This change also deletes more old code that didn't pan out. My goal here is to work towards a vision where the Cosmopolitan core libraries become less experimental and more focused on curation. This better reflects the current level of quality we've managed to achieve.
