There are various existing tests that call pthread_attr_init and then verify properties of the resulting initial values retrieved with pthread_attr_get* functions. However, those are missing coverage of the initial values retrieved with pthread_attr_getschedparam and pthread_attr_getstacksize. Add testing for initial values from those functions as well. (tst-attr2 covers pthread_attr_getdetachstate, pthread_attr_getguardsize, pthread_attr_getinheritsched, pthread_attr_getschedpolicy, pthread_attr_getscope. tst-attr3 covers some of those together with pthread_attr_getaffinity_np. tst-pthread-attr-sigmask covers pthread_attr_getsigmask_np. pthread_attr_getstack has unspecified results if called before the relevant attributes have been set, while pthread_attr_getstackaddr is deprecated.) Tested for x86_64.
