    Determine the per-course verification statuses for a given user.

    The possible statuses are:
        * VERIFY_STATUS_NEED_TO_VERIFY: The student has not yet submitted photos for verification.
        * VERIFY_STATUS_SUBMITTED: The student has submitted photos for verification,
          but has have not yet been approved.
        * VERIFY_STATUS_RESUBMITTED: The student has re-submitted photos for re-verification while
          they still have an active but expiring ID verification
        * VERIFY_STATUS_APPROVED: The student has been successfully verified.
        * VERIFY_STATUS_MISSED_DEADLINE: The student did not submit photos within the course's deadline.
        * VERIFY_STATUS_NEED_TO_REVERIFY: The student has an active verification, but it is
            set to expire before the verification deadline for the course.

    It is is also possible that a course does NOT have a verification status if:
        * The user is not enrolled in a verified mode, meaning that the user didn't pay.
        * The course does not offer a verified mode.
        * The user submitted photos but an error occurred while verifying them.
        * The user submitted photos but the verification was denied.

    In the last two cases, we rely on messages in the sidebar rather than displaying
    messages for each course.

        user (User): The currently logged-in user.

        dict: Mapping of course keys verification status dictionaries.
            If no verification status is applicable to a course, it will not
            be included in the dictionary.

                * status (str): One of the enumerated status codes.
                * days_until_deadline (int): Number of days until the verification deadline.
