include/linux/sched.h: don't use task->pid/tgid in same_thread_group/has_group_leader_pid
commit e1403b8edf669ff49bbdf602cc97fefa2760cb15 upstream. task_struct->pid/tgid should go away. 1. Change same_thread_group() to use task->signal for comparison. 2. Change has_group_leader_pid(task) to compare task_pid(task) with signal->leader_pid.
