    Dump SQLite table into various formats.

    This function is not exported.

    Arguments ('*' denotes required arguments):

    *   dbpath => *filename*

    *   exclude_columns => *array[str]*

    *   include_columns => *array[str]*

        Table name.

    *   wheres => *array[str]*

        Add WHERE clause.

    Returns an enveloped result (an array).

    First element (status) is an integer containing HTTP status code (200
    means OK, 4xx caller error, 5xx function error). Second element (msg) is
    a string containing error message, or 'OK' if status is 200. Third
    element (payload) is optional, the actual result. Fourth element (meta)
