[PATCH v1 0/4] add ref content check for files backend

Hi All:

This patch aims at adding ref content check for files backend. By the
RFC we have discussed, I add three types of checks.

1. Check regular ref content. I enhance the "parse_loose_ref_contents"
to validate the content of the regular ref and warn the user about the
trailing garbage.
2. Check symbolic ref content. Check the trailing garbage and content.
3. Check symlink ref by reusing the function introduced by #2.

The CI is passed:

Thanks,
Jialuo
