Update.
* pthread_attr_setschedparam.c: Don't test priority against limits here. Set ATTR_FLAG_SCHED_SET flag. * pthread_attr_setschedpolicy.c: Set ATTR_FLAG_POLICY_SET flag. * pthread_create.c (__pthread_create_2_1): Copy scheduling attributes from parent thread to child. If attribute is used and scheduling parameters are not inherited, copy parameters from attribute or compute them. Check priority value. * pthread_getschedparam.c: If the parameters aren't known yet get them from the kernel. * pthread_setschedparam.c: Set ATTR_FLAG_SCHED_SET and ATTR_FLAG_POLICY_SET flag for thread. * sysdeps/unix/sysv/linux/internaltypes.h: Define ATTR_FLAG_SCHED_SET and ATTR_FLAG_POLICY_SET. * sysdeps/pthread/createthread.c: Use tgkill if possible.
