[RTNETLINK]: Add rtnetlink notification interface
Adds rtnl_notify() to send rtnetlink notification messages and rtnl_set_sk_err() to report notification errors as socket errors in order to indicate the need of a resync due to loss of events. nlmsg_report() is added to properly document the meaning of NLM_F_ECHO.
