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

First is the patch to add IFLA_EVENT attribute to the netlink message.  It
supports only currently white-listed events.
Like before, this is just an attribute that gets added to the rtnetlink
message only when the messaged was generated as a result of a netdev event.
In my case, this is necessary since I want to trap NETDEV_NOTIFY_PEERS
event (also possibly NETDEV_RESEND_IGMP event) and perform certain actions
in user space.  This is not possible since the messages generated as
a result of netdev events do not usually contain any changed data.  They
are just notifications.  This patch exposes this notification type to
userspace.

Second, I remove duplicate messages that a result of a change to bonding
options.  If netlink is used to configure bonding options, 2 messages
are generated, one as a result NETDEV_CHANGEINFODATA event triggered by
bonding code and one a result of device state changes triggered by
netdev_state_change (called from do_setlink).

V6: Updated names and refactored to make it less tied to netdev events.

V5: Rebased.  Added iproute2 patch to the series.
V4:
  * Removed the patch the removed NETDEV_CHANGENAME from event whitelist.
    It doesn't trigger duplicate messages since name changes can only be
    done while device is down and netdev_state_change() doesn't report
    changes while device is down.
  * Added a patch to clean-up duplicate messages on bonding option changes.

V3: Rebased.  Cleaned-up duplicate event.

V2: Added missed events (from David Ahern)
