ref-filter: add objectsize to used_atom

Browse Source 
When the support for "objectsize:disk" was bolted onto the
existing support for "objectsize", it didn't follow the
usual pattern for handling "atomtype:modifier", which reads
the <modifier> part just once while parsing the format
string, and store the parsed result in the union in the
used_atom structure, so that the string form of it does not
have to be parsed over and over at runtime (e.g. in
grab_common_values()).

Add a new member `objectsize` to the union `used_atom.u`,
so that we can separate the check of <modifier> from the
check of <atomtype>, this will bring scalability to atom
`%(objectsize)`.
