* include/link.h (struct link_map): Remove l_opencount. Add l_removed.
	Change type of l_idx to int.
	* elf/dl-close.c: Basically rewrite.  Do not use l_opencount to
	determine whether a DSO has to be unloaded.  Instead compute this
	in this function.
	* elf/dl-deps.c: No need to manipulate l_opencount anymore.
	* elf/dl-lookup.c: Likewise.
	* elf/rtld.c: Likewise
	* elf/dl-open.c: Likewise.  Use l_init_called to determine whether
	object was just loaded.
	* elf/dl-fini.c: Bump l_direct_opencount instead of l_opencount.
	* elf/dl-load.c (_dl_map_object_from_fd): Do not recognize DSO which
	is about to be unloaded as a match.
	(_dl_map_object): Likewise.
	* elf/do-lookup.h (do_lookup_x): Do not look into DSO which is about
	to be unloaded.
	* elf/circleload1.c: Don't use l_opencount anymore.
	* elf/neededtest.c: Likewise.
	* elf/neededtest2.c: Likewise.
	* elf/neededtest3.c: Likewise.
	* elf/neededtest4.c: Likewise.
	* elf/unload.c: Likewise.
	* elf/unload2.c: Likewise.
	* elf/loadtest.c: Likewise.

	* elf/rtld.c: Preloading errors are now never fatal.

	* elf/Makefile: Add rules to build and run unload5 test.
	* elf/unload5.c: New file.
