From: ZheNing Hu <adlternative@xxxxxxxxx>
Add new formatting option `%(raw)`, which will print the raw
object data without any changes. 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
a structured string (end with '\0').
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)` should not combine 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.
