Based on #15124; only the last commit is new here.

On Linux, with -R -H, a symlink met in the tree was stat'd itself but the change went to the file it points to, so --from was judged on the link's owner, and -v reported the link's owner. GNU 9.12 judges and reports the target.

Under -R -H the target is now stat'd for --from and the report, and with --from held for the change. A link whose target can't be stat'd is reported ("cannot dereference") and left alone, as with GNU 9.12. Tests: test_chown_from_judges_symlink_target_under_big_h, test_chown_dangling_symlink_under_big_h.
