    Mark new threads as global signal receivers
    
    * sysdeps/mach/hurd/pt-sigstate-init.c (__pthread_sigstate_init):
    Call _hurd_sigstate_set_global_rcv for newly created threads.
    * sysdeps/mach/pt-thread-halt.c (__pthread_thread_halt):
    Call _hurd_sigstate_delete on terminated threads.
