Move __cxa_thread_atexit* to its own .c file to avoid pulling the code (w/ _dlctl reference) into static executables. It's all Mark's code so put his preferred copyright on it.

Minimal maintenance to make this mess slightly less confusing: queue -> list; mention "intrusive"; element -> member at one place; delete a bogus remark that maybe referred to a long-gone implementation in VAX assembly code. Much more could be improved, but i don't want to waste too much time here.

XPG requires insque() and remque() to work with linear lists and not just circular lists. Amazingly, they managed to extend the requirements to no longer match the behavior of the VAX instructions they were modeled after, so the trivial VAX ASM versions have to go. Nice job breaking it, X/Open!

Some people still argue that rand(3) and random(3) have suitable deterministic use cases, so explain the situation a bit more. Since the 80's, I estimate around 5 algorithm changes, so any chosen seed is unrepeatable UB.

thread_atexit.c

Complete the ld.so boot cleanup: move most libc initialization from _csu_finish() to _libc_preinit(), which is an .init_array function in shared libc (and mark it INITFIRST) or a .preinit_array function in static libc, grabbing the _dl_cb callback there from ld.so. Then in _csu_finish(), invoke the dl_clean_boot() callback to free ld.so's startup bits before main() gets control.
