  Moved lower case conversion of database names to check_db_name()

  Fix to be able to use 4.0 error message files
sql/sql_db.cc:
  Moved lower case conversion of database names to check_db_name()
sql/sql_parse.cc:

  Added checking of lower_case_table_names for mysql_table_dump() and
  mysql_list_fields()

  Moved lower case conversion of database names to check_db_name()
sql/table.cc:
  Convert database names to lower case in check_db-name() if --lower-case-table-names is used.
