For root the functions util_path_is_readable() and util_path_is_writable() do not take the path's permissions into account. The function access() succeeds as root is allowed to read/write any file regardless of its permissions. Introduce the functions util_path_is_readonly_file() and util_path_is_writeonly_file() to test whether a path is a regular file and is either read-only (neither user, group, nor other have write permission, but one or more of user, group, and other have read permission) or write-only (neither user, group, nor other have read permission, but one or more of user, group, and other have write permission).
