	* elf/dladdr.c: Remove #include <setjmp.h>, we don't use it.

	* shlib-versions: Set libdl=2.

	* elf/dl-deps.c (_dl_map_object_deps): Use a linked list of alloca'd
 	elements and then scan it to fill the single malloc'd array, instead
 	of using realloc to grow the array in the first pass.  _dl_map_object
	may do some mallocs that break our stream of reallocs, and the minimal
	realloc can't handle that.

	* elf/dl-init.c (_dl_init_next): Take argument, link_map whose
 	searchlist describes the piece of the DT_NEEDED graph to be
 	initialized.
	* elf/link.h: Update prototype.
	* sysdeps/i386/dl-machine.h (RTLD_START): Pass _dl_loaded as argument
	to _dl_init_next.
	* sysdeps/m68k/dl-machine.h: Likewise.
	* elf/dl-deps.c (_dl_open): Pass new object as arg to _dl_init_next.

	* elf/link.h (struct link_map): Add `l_reserved' member, soaking up
	extra bits in last byte.
	* elf/dl-deps.c (_dl_map_object_deps): Use that for mark bit to avoid
	putting dup elts in search list.

	* elf/dlclose.c: Use MAP->l_searchlist to find deps to close.

	* elf/dlsym.c: Don't tweak linked list.  Scope array given to
	_dl_lookup_symbol does the right thing.
