       Define a data of the m17n database. The mdatabase_define() function defines a data that has tags tag0
       through tag3 and additional information extra_info.

       loader is a pointer to a function that loads the data from the database. This function is called from the
       mdatabase_load() function with the two arguments tags and extra_info. Here, tags is the array of tag0
       through tag3.

       If loader is NULL, the default loader of the m17n library is used. In this case, extra_info must be a
       string specifying a filename that contains the data.

           If the operation was successful, mdatabase_define() returns a pointer to the defined data, which can
           be used as an argument to mdatabase_load(). Otherwise, it returns NULL.
