Subject: include/linux/sched.h: don't use task->pid/tgid in same_thread_group/has_group_leader_pid

include/linux/sched.h: don't use task->pid/tgid in same_thread_group/has_group_leader_pid

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.
