* allocatestack.c (allocate_stack): Initialize robust_list.

Browse Source 
* init.c (__pthread_initialize_minimal_internal): Likewise.
	* descr.h (struct xid_command): Pretty printing.
	(struct pthread): Use __pthread_list_t or __pthread_slist_t for
	robust_list.  Adjust macros.
	* pthread_create.c (start_thread): Adjust robust_list handling.
	* phtread_mutex_unlock.c: Don't allow unlocking from any thread
	but the owner for all robust mutex types.
	* sysdeps/unix/sysv/linux/i386/bits/pthreadtypes.h: Define
	__pthread_list_t and __pthread_slist_t.  Use them in pthread_mutex_t.
	* sysdeps/pthread/pthread.h: Adjust mutex initializers.
