From: ZheNing Hu <adlternative@gmail.com>

Add `cat_file_mode` member to struct `ref_format`. When
`cat-file --batch` use ref-filter logic later, it can help us
reject atoms in verify_ref_format() which cat-file cannot use,
e.g. `%(refname)`, `%(push)`, `%(upstream)"...

Add batch_test_atom() to t/t1006-cat-file.sh and add check
for cat-file --batch, this can help us clearly show which
atoms cat-file accepts and which atoms it rejects.
