[PATCH 0/8] [GSOC] [RFC] ref-filter: code logic optimization

["ZheNing Hu via GitGitGadget" <gitgitgadget@gmail.com>]

Last time I submitted a very long patch series:
https://lore.kernel.org/git/pull.1016.git.1628842990.gitgitgadget@gmail.com/
My mentor Christian suggested to split the performance optimization part
out, so this patch series used to optimize code logic in ref-filter.

Changes in this patch series:

 1. Remove grab_oid to reduce unnecessary string comparison.
 2. Use atom_type in grab_person() and merge the two for loops.
 3. Remove strlen() and introducing xstrvfmt_len() and xstrfmt_len() to
    reduce strlen() overhead.
 4. Introduction ref_filter_slopbuf[1] to reduce memory allocation.
 5. Add deref to struct used_atom to increase the readability of the code.
 6. Introduction symref_atom_parser() to increase the readability of the
    code.
 7. Use switch/case instread of if/else to increase the readability of the
    code.
