René Kijewski b54962689a posix: Add pthread_cleanup handlers ... With `pthread_cleanup_(push|pop)` you can define a function that should be ran if the thread is exited while it is inside this scope. A thread can be ended here through an explicit call to `pthread_exit()`, or if cancellation was requested and a cancellation point was hit. `pthread_cleanup_*` is mostly only useful together with cancellation points, and cancellation points are only useful with a cleanup functionality. Cancellation points are at least partially implemented by means of `pthread_testcancel()`. C.f. ["Cancellation Points"][1].
