* pthread/pt-alloc.c: Don't include <bits/atomic.h>.
(__pthread_free_threads): Change to a struct __pthread *.
(__pthread_free_threads_lock): New variable.
(__pthread_alloc): When looking for a TCB to reuse, iterate over
__pthread_free_threads taking the first for which the STATE field
is PTHREAD_TERMINATED. When reusing a TCB, first call
__pthread_thread_halt on it.
* pthread/pt-dealloc.c: Don't include <bits/atomic.h>.
(__pthread_free_threads): Change to a struct __pthread *.
(__pthread_free_threads_lock): New declaration.
(__pthread_dealloc): Enqueue PTHREAD on __PTHREAD_FREE_THREADS.
Set PTHREAD->STATE to PTHREAD_TERMINATED after everything else.
* pthread/pt-join.c (pthread_join): Call __pthread_thread_halt
before destroying the thread. When destroying the thread, call
__pthread_thread_dealloc on it.
* pthread/pt-detach.c (pthread_detach): If destroying the thread,
call __pthread_thread_halt before deallocating the stack. In this
case, also call __pthread_thread_dealloc on the tcb.
* pthread/pt-exit.c (pthread_exit): Call __pthread_dealloc only if
the thread is detached and then as the last thing we do before
calling __pthread_thread_halt.
* pthread/pt-internal.h (__pthread_thread_halt): Remove argument
NEED_DEALLOC. Update users.
* sysdeps/mach/pt-thread-halt.c (__pthread_thread_halt): Remove
argument need_dealloc.
* sysdeps/mach/hurd/pt-sysdep.h (PTHREAD_SYSDEP_MEMBERS): Add field
have_kernel_resources.
* sysdeps/mach/hurd/pt-thread-alloc.c (__pthread_thread_alloc): If
THREAD->HAVE_KERNEL_RESOURCES is true, just return. After
allocating the resources, set THREAD->HAVE_KERNEL_RESOURCES to
true.
