Update.
	* elf/elf.h: Add various DF_1_*, DTF_1_*, and DF_P1_* entries.
	* elf/dl-close.c (_dl_close): Don't close an object if it is marked
	with nodelete.
	* elf/dl-open.c (dl_open_worker): Pass RTLD_NOLOAD as new parameter
	to _dl_map_object.  Return immediately if no object loaded.
	Set DF_1_NODELETE bit in l_flags_1 if RTLD_NODELETE was passed.
	* elf/dynamic-link.h (elf_get_dynamic_info): Copy DT_FLAGS_1 entry
	if it exists into l_flags_1 word.
	* elf/dl-load.c (_dl_map_object_from_fd): Take no parameter and use
	it to determine whether loading is wanted or not.
	(_dl_map_object): Likewise.
	Call _dl_map_object_from_fd with new parameter.
	* sysdeps/generic/ldsodefs.h: Update prototype.
	* elf/dl-deps.c: Add new parameter to _dl_map_object calls.
	* elf/rtld.c: Likewise.
	* elf/Makefile (tests): Add noload.  Add rules to generate noload.
	* elf/noload.c: New file.
	* include/link.h (struct link_map): Add l_feature_1 and l_flags_1.
	* sysdeps/generic/bits/dlfcn.h: Define RTLD_NOLOAD and RTLD_NODELETE.
	* sysdeps/mips/bits/dlfcn.h: Likewise.
