* nis/nis_table.c (nis_list): If __follow_path fails in the new

	code, make sure the nis_freeresult call doesn't crash and that the
	result is reported correctly.

	* nis/nis_table.c (nis_list): Handle FOLLOW_PATH | ALL_RESULTS
	when callback is NULL.

	* nis/Versions (libnss_nisplus): Add
	_nss_nisplus_initgroups_dyn@@GLIBC_PRIVATE.
	* nis/Makefile (libnss_nisplus-routines): Add nisplus-initgroups.
	* nis/nss_nisplus/nisplus-grp.c (tablename_val, tablename_len,
	_nss_create_tablename): Rename to...
	(grp_tablename_val, grp_tablename_len, _nss_grp_create_tablename):
	... these.  No longer static.
	(internal_setgrent): Adjust users.
	(_nss_nisplus_getgrnam_r, _nss_nisplus_getgrgid_r): Likewise.
	Don't use locking around _nss_grp_create_tablename call.
	* nis/nss_nisplus/nisplus-initgroups.c: New file.
