	* pthread/pt-alloc.c (alloc_init): Update to new semantics.  Do

	__hurd_threadvar_location with the initial stack.  This is
	completely bogus; removed.  Neither can we use the TSD on the new
	stack: once the initial thread returns to the libc initialization
	code, libc overwrites it.  Thus, we shift the TSD by a pointer and
	use the first word of the stack to store the self pointer.
	* sysdeps/mach/hurd/pt-sysdep.h (_HURD_THREADVAR_THREAD): Removed.
	(_pthread_self): Update to reflect new semantics.
