It will help further to migrate all cat-file formatting logic from cat-file to ref-filter. The raw data of blob, tree objects may contain '\0', but most of the logic in `ref-filter` depands on the output of the atom being text (specifically, no embedded NULs in it). E.g. `quote_formatting()` use `strbuf_addstr()` or `*._quote_buf()` add the data to the buffer. The raw data of a tree object is `100644 one\0...`, only the `100644 one` will be added to the buffer, which is incorrect. Therefore, add a new member in `struct atom_value`: `s_size`, which can record raw object size, it can help us add raw object data to the buffer or compare two buffers which contain raw object data. Beyond, `--format=%(raw)` cannot be used with `--python`, `--shell`, `--tcl`, `--perl` because if our binary raw data is passed to a variable in the host language, the host languages may cause escape errors.
