Re: [PATCH v3 02/16] ref-filter: include reference to 'used_atom' within 'atom_value'

> Ensure that each 'atom_value' has a reference to its corresponding
> 'used_atom'. This let's us use values within 'used_atom' in the
> 'handler' function.
>
> Hence we can get the %(align) atom's parameters directly from the
> 'used_atom' therefore removing the necessity of passing %(align) atom's
> parameters to 'atom_value'.
>
> This also acts as a preparatory patch for the upcoming patch where we
> introduce %(if:equals=) and %(if:notequals=).
