[PATCH v3 1/2] [GSOC] ref-filter: add objectsize to used_atom

["ZheNing Hu via GitGitGadget" <gitgitgadget@xxxxxxxxx>]

From: ZheNing Hu <adlternative@xxxxxxxxx>

Since "objectsize:size" is composed of two parts,
"type:attribute". However, the original implementation
did not decouple the two parts "type" and "attribute" well,
we still need to judge separately whether the atom is
"objectsize" or "objectsize:disk" in `grab_common_values()`.

Add a new member `objectsize` to the union `used_atom.u`,
so that we can separate the judgment of atom type from the
judgment of atom attribute, This will bring scalability to
atom `%(objectsize)`.
