Make valid_atom as a function parameter, there could be another variable further. Need that for further reusing of formatting logic in cat-file.c. We do not need to allow users to pass their own valid_atom variable in global functions like verify_ref_format because in the end we want to have same set of valid atoms for all commands. But, as a first step of migrating, I create further another version of valid_atom for cat-file.
