Update.

Browse Source 
* elf/rtld.c (_dl_start_final): Allocate TLS and initialize
	thread-pointer as soon as possible.
	* sysdeps/generic/ldsodefs.h: Include <tls.h>.  Define first TLS
	elements in rtld_global.
	* sysdeps/generic/tls.h: New file.
	* elf/Makefile (distribute): Add tls.h.
	* sysdeps/i386/dl-machine.h (elf_machine_rel): Add support for TLS
	relocations.  Not complete yet.

	* resolv/resolv.h: Allow user to define __need_res_state and only
	define __res_start structure then.
	* include/resolv.h: Only declare functions if _RESOLV_H_ is defined.
