Remove bits/pt-atomic.h

* pthread/pt-create.c: Include <atomic.h> instead of <bits/pt-atomic.h>.
(__pthread_total): Change type from __atomic_t to unsigned int.
(__pthread_create_internal): Use atomic_increment and atomic_decrement
instead of __atomic_inc and __atomic_dec.
* pthread/pt-dealloc.c: Include <atomic.h> instead of
<bits/pt-atomic.h>.
(__pthread_dealloc): Use atomic_decrement_and_test instead of
__atomic_dec_and_test.
* pthread/pt-exit.c: Include <atomic.h> instead of <bits/pt-atomic.h>.
(__pthread_exit): Use atomic_decrement_and_test instead of
__atomic_dec_and_test.
* pthread/pt-internal.h: Include <atomic.h> instead of
<bits/pt-atomic.h>.
(struct __pthread): Use unsigned int type for nr_refs field instead of
__atomic_t.
(__pthread_total): Use unsigned int type instead of nr_refs.
