Remarks
A node can deregister a key anytime after registration. Additionally, if an application calls DrtClose, all keys are deregistered by the DRT infrastructure.
Only the application that registered they key may deregister it. An application can deregister a key from the local node. Upon completion the function triggers a DRT_EVENT_LEAFSET_KEY_CHANGE event; informing the application and other nodes participating in the DRT mesh of the deregistration.
