* allocatestack.c (allocate_stack): Initialize robust_list.cvs/fedora-glibc-20060213T0650
* 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.
