* sysdeps/generic/libc-tls.c (__libc_setup_tls): Cope with zero ALIGN.
	* malloc/hooks.c [_LIBC && (USE___THREAD || (USE_TLS && !SHARED))]
	(malloc_starter, memalign_starter, free_starter): Don't define these.
	* malloc/malloc.c [_LIBC && (USE___THREAD || (USE_TLS && !SHARED))]:
	Don't declare them either.
	* malloc/arena.c (ptmalloc_init) [_LIBC && USE_TLS]: Don't call
	__pthread_initialize, so no need to set hooks to *_starter.
	(ptmalloc_init_minimal): New function, broken out of ptmalloc_init.
	[_LIBC && SHARED && USE_TLS && !USE___THREAD]
	(__libc_malloc_pthread_startup): New function.
	* malloc/Versions (libc: GLIBC_PRIVATE): New set, add that function.

	* malloc/hooks.c (memalign_starter): New function.
	* malloc/malloc.c: Declare it.
	* malloc/arena.c (save_memalign_hook): New variable.
	(ptmalloc_init): Set __memalign_hook to memalign_starter.

	* elf/dl-minimal.c (free): Clear the memory.
	(calloc): Just call malloc, knowing all memory it returns is cleared.

	* sysdeps/generic/dl-tls.c (allocate_dtv): Use calloc instead of
	malloc and memset; calloc can avoid the zeroing when redundant.
	(_dl_tls_setup): Likewise.
	* elf/dl-load.c (decompose_rpath): Likewise.
	* sysdeps/generic/libc-tls.c (__libc_setup_tls): Comment out memset
	call, since memory from sbrk at startup is already zero.

	* elf/rtld.c (_dl_start, dl_main): TLS_INIT_TP macro now returns an
	error string for failure, null for success.  Update callers.
	* sysdeps/generic/libc-tls.c (__libc_setup_tls): Likewise.
	* elf/dl-load.c (_dl_map_object_from_fd): Likewise.
