 * @title: QmiProxy
 * @short_description: QMI proxy handling routines
 *
 * The #QmiProxy will setup an abstract socket listening on a predefined
 * address, and will take care of synchronizing the access to a set of shared
 * QMI ports.
 *
 * Multiple #QmiDevice objects may be connected to the #QmiProxy at any given
 * time. The #QmiProxy acts as a stateless proxy for non-CTL services (messages
 * are transferred unmodified), and as a stateful proxy for the CTL service (all
 * remote #QmiDevice objects will need to share the same CTL message sequence
 * ID).
