* sysdeps/generic/ldsodefs.h (struct rtld_global): Move all [USE_TLS]

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

	* sysdeps/i386/i486/bits/string.h (__strcpy_g): Add dummy output
	operand for DEST memory.  Fix dummy input operand to use SRC.
	Reported by Davin McCall <davmac@ozonline.com.au>.

	* sysdeps/generic/libc-tls.c (__libc_setup_tls): Account for TCB
	alignment when initializing the DTV entry.

	* elf/dl-load.c (_dl_map_object_from_fd): If we hit a TLS segment
	when TLS has not been set up, try to set it up if we can.
	* elf/tst-tls4.c: Revert last change.
	* elf/tst-tls5.c: Likewise.
	* elf/tst-tls6.c: Likewise.
	* elf/tst-tls7.c: Likewise.
	* elf/tst-tls8.c: Likewise.
	* elf/tst-tls9.c: Likewise.

	* sysdeps/generic/dl-tls.c [SHARED] (_dl_tls_setup): New function.
	* sysdeps/generic/ldsodefs.h: Declare it.
	* elf/Versions (ld: GLIBC_PRIVATE): Add it.
	* sysdeps/generic/libc-tls.c (init_slotinfo): New static inline
	function, broken out of __libc_setup_tls.
	(init_static_tls): Likewise.
	(__libc_setup_tls): Call them.
	(_dl_tls_setup): New function, uses new subroutines.

	* elf/dl-close.c (free_slotinfo): Make argument pointer to pointer.
	Clear the pointer when returning true.
	(libc_freeres_fn) [SHARED]: If GL(dl_initial_dtv) is null, free the
	first element of the slotinfo list too.

	* sysdeps/generic/dl-tls.c (_dl_determine_tlsoffset): Define only if
	[SHARED].

	* sysdeps/generic/ldsodefs.h (_dl_next_tls_modid): Declare as hidden.
	(_dl_determine_tlsoffset): Likewise.

	* elf/rtld.c (_dl_initial_error_catch_tsd): Renamed from
	startup_error_tsd, made global.
	(dl_main): Update initialization.
	* elf/dl-tsd.c: Likewise.
	* sysdeps/generic/ldsodefs.h: Declare it.
