Merge branch 'rtnetlink-event-type'

====================
rtnetlink: Updates to rtnetlink_event()

This series came out of the conversation that started as a result
my first attempt to add netdevice event info to netlink messages.

This series converts event processing to a 'white list', where
we explicitely permit events to generate netlink messages.  This
is meant to make people take a closer look and determine wheter
these events should really trigger netlink messages.

I am also adding a V2 of my patch to add event type to the netlink
message.  This version supports all events that we currently generate.

I will also update my patch to iproute that will show this data
through 'ip monitor'.

I actually need the ability to trap NETDEV_NOTIFY_PEERS event
(as well as possible NETDEV_RESEND_IGMP) to support hanlding of
macvtap on top of bonding.  I hope others will also find this info usefull.

V2: Added missed events (from David Ahern)
