sctp: add SCTP_AUTH_FREE_KEY type for AUTHENTICATION_EVENT
This patch is to add SCTP_AUTH_FREE_KEY type for AUTHENTICATION_EVENT, as described in section 6.1.8 of RFC6458. SCTP_AUTH_FREE_KEY: This report indicates that the SCTP implementation will no longer use the key identifier specified in auth_keynumber. After deactivating a key, it would never be used again, which means it's refcnt can't be held/increased by new chunks. But there may be some chunks in out queue still using it. So only when refcnt is 1, which means no chunk in outqueue is using/holding this key either, this EVENT would be sent. When users receive this notification, they could do DEL_KEY sockopt to remove this shkey, and also tell the peer that this key won't be used in any chunk thoroughly from now on, then the peer can remove it as well safely.
