Returning 'SQL_DOWN' allows sql.c to reconnect and try again, in most cases

sql_select_query: returns -1 on failure, SQL_DOWN on 'socket not connected'
sql_query: returns -1 on failure, SQL_DOWN on 'socket not connected'
sql_store_result: returns -1 on failure, SQL_DOWN on 'socket not connected'
sql_num_fields: cannot return an error, complains if zero fields
sql_finish_select_query: returns 0 always
sql_finish_query: does nothing, returns 0
sql_free_result: returns 0 always, mysql_free_result has no return value
sql_release_socket: returns 1 always
sql_fetch_row: returns 0 if ok, SQL_DOWN on 'socket not connected', row is
		in sqlsocket->row now

TODO:

db2/freetds/iodbc/unixodbc:
     for the above functions, where it can return SQL_DOWN, determine if an
     error with the database exists, if it is down, and return SQL_DOWN
