thread: use pthread_cleanup_{push,pop} Each xthr_create wraps the passed in user function in hopes of executing code after the function returns to clean up some libjeffpc-internal thread-local state. This needs to happen even if the thread called pthread_exit. The pthread_cleanup_{push,pop} functions are the POSIX-provided way to run such cleanup code.
