/**
* DConfEngineMessage:
*
* This structure represents a number of DBus method call messages that #DConfEngine would like to send.
*
* #DConfEngine itself is unaware of a particular DBus or main loop implementation. As such, all requests are
* synchronous and non-blocking, but most of them produce a #DConfEngineMessage describing messages that must be
* sent in order for the operation to be completed.
*
* @bus_name, @object_path, @interface_name, @method_name specify the respective header fields of the method
* call. These are always equal for all of the calls contained within a single #DConfEngineMessage.
*
* @reply_type is the expected reply type of the method call. This is also the same for all calls contained
* within a single #DConfEngineMessage.
*
* @n_messages is the number of messages to send.
*
* @bus_types and @parameters are both arrays, of length @n_messages. Each element of @bus_type is the bus type
* to send each method call on and each of @parameters is the body of that call. The reason that there may be
* several messages is that a single dconf "watch" operation may need to send multiple DBus "AddMatch" calls
* (and usually to multiple busses).
*
* Each element in @bus_types is either 'y' for system bus or 'e' for session bus.
*
* A #DConfEngineMessage is always stack-allocated by the caller. It must be cleared using
* dconf_engine_message_destroy() when done. It may be copied using dconf_engine_message_copy().
