Subject: * elf/dl-lookup.c (_dl_debug_bindings): Remove unised symbol_scope

	argument.
	(_dl_lookup_symbol_x): Adjust caller.

	* sysdeps/generic/ldsodefs.h (struct link_namespaces): Remove
	_ns_global_scope.
	* elf/rtld.c (dl_main): Don't initialize _ns_global_scope.

	* elf/dl-libc.c: Revert l_scope name changes.
	* elf/dl-load.c: Likewise.
	* elf/dl-object.c: Likewise.
	* elf/rtld.c: Likewise.
	* elf/dl-close.c (_dl_close): Likewise.
	* elf/dl-open.c (dl_open_worker): Likewise.  If not SINGLE_THREAD_P,
	always use __rtld_mrlock_{change,done}.  Always free old scope list
	here if not l_scope_mem.
	* elf/dl-runtime.c (_dl_fixup, _dl_profile_fixup): Revert l_scope name
	change.  Never free scope list here.  Just __rtld_mrlock_lock before
	the lookup and __rtld_mrlock_unlock it after the lookup.
	* elf/dl-sym.c: Likewise.
	* include/link.h (struct r_scoperec): Remove.
	(struct link_map): Replace l_scoperec with l_scope, l_scoperec_mem
	with l_scope_mem and l_scoperec_lock with l_scope_lock.
