AMP channels can be moved between BR/EDR and AMP controllers using a
sequence of signals. Every attempted channel move involves a series of
four signals:

   Move Initiator                 Move Responder
        |                                 |
        |       Move Channel Request      |
        |  ---------------------------->  |
        |                                 |
        |       Move Channel Response     |
        |  <----------------------------  |
        |                                 |
        |       Move Channel Confirm      |
        |  ---------------------------->  |
        |                                 |
        |  Move Channel Confirm Response  |
	|  <----------------------------  |

All four signals are sent even if the move fails.
