Why is this a breaking change :)

[jiangliu]

Why is this a breaking change :)

This PR introduces new crates, so existing code may fail to compile, so marked as "breaking changes".
It doesn't mean incompatibility,

[imeoer]

Is it necessary to keep it?

[jiangliu]

They should be removed:)

Is this file specially added?

[jiangliu]

The builder has a ut case, which uses this file, though it's ignored currently.

   #[ignore]
    #[test]
    fn test_build_stargz_toc() {
        let tmp_dir = vmm_sys_util::tempdir::TempDir::new().unwrap();
        let tmp_dir = tmp_dir.as_path().to_path_buf();
        let root_dir = &std::env::var("CARGO_MANIFEST_DIR").expect("$CARGO_MANIFEST_DIR");
        let source_path =
            PathBuf::from(root_dir).join("../tests/texture/stargz/estargz_sample.json");
