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.
