Backport reap_children() and threading_cleanup() enhancements from master to 3.6 to make tests more reliables, reduce random failures on Python CIs.

See also bpo-31258 for Python 2.7

At this point, I'm not sure that I want to make threading_cleanup() stricter, since it's tricky to fix all dangling threads in all tests. At least, I opened an issue for 3.6 as a placeholder if we need to backport a few fixes.

See also bpo-31234 where I already backported a few fixes to 3.6.

While backporting fixes on tests make sense, I'm not sure that it's doable to make regrtest more strict. It took me a while to fix all "dangling threads" and "dangling processes" on the master branch, and 6 months later, I'm not done yet. There are tricky issues the socketserver module (bpo-31233, bpo-31151). So I prefer to abandon this issue, and only backport test fixes.
