  This series fixes the std::shared_timed_mutex negative timeout bug[0] and
adds test cases to the other standard library wait functions that take
a timeout. Those test cases revealed a similar bug in std::binary_semaphore
and std::counting_semaphore which I've also fixed.

This series does nothing to address the problems I identified[1] in how
std::shared_timed_mutex deals with error returns that made this bug even
more serious[2]. I'll deal with that separately, ideally once I receive
some guidance as to the best way forward.

Thanks.

Mike.
