This doesn't run any separate tasks: sending and receiving are done in
the task that calls those methods. It's suitable for implementing servers:
several worker tasks can receive requests and send replies.
For a typical client pattern, see :class:`DBusRouter`.
Implements trio's channel interface for Message objects.

To be used like::
async with conn.router() as req:
reply = await req.send_and_get_reply(msg)
While the router is running, you shouldn't use :meth:`receive`.
Once the router is closed, you can use the plain connection again.

You can call methods on the proxy object, such as ``await bus_proxy.Hello()``
to make a method call over D-Bus and wait for a reply. It will either
return a tuple of returned data, or raise :exc:`.DBusErrorResponse`.
The methods available are defined by the message generator you wrap.
:param msggen: A message generator object.
