With de_thread now calling exchange_tids has_group_leader_pid no longer
makes any sense and is equivalent to calling thread_group_leader.

As there are only 2 remaining users of has_group_leader_pid let's
update the code and get rid of has_group_leader_pid.

There is one extra patch to lookup_task that performs that unifies
to code paths that become identical when has_group_leader_pid went
away.

Eric W. Biederman (4):
posix-cpu-timer: Tidy up group_leader logic in lookup_task
posix-cpu-timer: Unify the now redundant code in lookup_task
exec: Remove BUG_ON(has_group_leader_pid)
signal: Remove has_group_leader_pid
