* sysdeps/generic/libc-tls.c: Undo last patch.

* 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.

* 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.

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.

members to the end, so a libpthread compiled with !USE_TLS will still
find other members properly.

operand for DEST memory. Fix dummy input operand to use SRC.

first element of the slotinfo list too.

argument TCBSIZE <= TLS_INIT_TCB_SIZE, not just if it's zero.
* sysdeps/generic/dl-tls.c (_dl_allocate_tls_init): Check l_tls_offset

* include/pthread.h: Don't declare __pthread_initialize_minimal as
weak here; we declare it weak or strong in the one place we use it.
* sysdeps/generic/libc-start.c: ... which is here.
Don't make the decl weak if [USE_TLS], since static programs need TLS
setup even when single-threaded.
