[PATCH 00/19] [GSOC] cat-file: reuse ref-filter logic

This patch series make cat-file reuse ref-filter logic.

Change from last version:

 1. Declare buf_size in if (atom_type == ATOM_RAW) block.
 2. Modify the code style of the test.
 3. Delete "use_textconv" and "use_filter" flag. Instead, add member
    cat_file_cmdmode to struct ref_array_item.
 4. Add function reject_atom() to enhance the readability of the code.
 5. Create p1006-cat-file.sh for performance regression testing.
 6. Use a "fast path" to output object data to reduce the performance
    degradation of cat-file --batch with the suggest of Ævar Arnfjörð
    Bjarmason.
