optimize get_current_dir_name to reduce stack bloat our getcwd already (as an extension) supports allocation of a buffer when the buffer argument is a null pointer, so there's no need to duplicate the allocation logic in this wrapper function. duplicating it is actually harmful in that it doubles the stack usage from PATH_MAX to 2*PATH_MAX.
