util.stanza: Add add_error() to simplify adding error tags to existing stanzas Some fiddling is required now in error_reply() to ensure the cursor is in the same place as before this change (a lot of code apparently uses that feature).

local record lib
	create : function (narr:integer, nrec:integer):table
	pack : function (...:any):{any}
	move : function (table, integer, integer, integer, table) : table
end
return lib
