Since we are moving some code handling out of the dataplane
and into zebra proper, lets move the protodown r bit as well.

Read in STP state changes for a Single Vxlan Device
via bridge vlan netlink messages. Map the vlanid to a
VNI in the SVD table and treat it similar to how
we handle proto down of the Vxlan device traditionally
in a non-SVD device scenario.
Forwarding == Interface UP
Blocking == Interface DOWN

'bridge vni add vni <id> dev <vxlan device>'
generates new RTM_NEWTUNNEL and RTM_DELTUNNEL
to add or remove vni to l3vxlan device.
Register new RTNLGRP_TUNNEL group to receive
new netlink notification.
Callback for the new RTM_xxxTUNNEL.

Remove the old protodown dplane path install on the main thread.

Add support for setting the protodown reason code.
https://github.com/torvalds/linux/commit/829eb208e80d6db95c0201cb8fa00c2f9ad87faf
These patches handle all our netlink code for setting the reason.
For protodown reason we only set `frr` as the reason externally
but internally we have more descriptive reasoning available via
`show interface IFNAME`. The kernel only provides a bitwidth of 32
that all userspace programs have to share so this makes the most sense.
Since this is new functionality, it needs to be added to the dplane
pthread instead. So these patches, also move the protodown setting we
were doing before into the dplane pthread. For this, we abstract it a
bit more to make it a general interface LINK update dplane API. This
API can be expanded to support gernal link creation/updating when/if
someone ever adds that code.
We also move a more common entrypoint for evpn-mh and from zapi clients
like vrrpd. They both call common code now to set our internal flags
for protodown and protodown reason.
Also add debugging code for dumping netlink packets with
protodown/protodown_reason.

Move the handler for incoming interface address events
to a neutral source file - it's not netlink-specific and
shouldn't have been in a netlink file.

Add new apis for dplane interface address handling, based on
the existing api. The existing api is basically split in two:
the first part processes an incoming netlink message in the
dplane pthread, creating a dplane context with info about
the event. The second part runs in the main pthread and uses
the context data to update an interface or connected object.

This action is initiated by nhrp and has been stubbed when
moving to zebra. Now, a netlink request is forged to set
the link interface of a gre interface if that gre interface
does not have already a link interface.

The FSF's address changed, and we had a mixture of comment styles for
the GPL file header. (The style with * at the beginning won out with
580 to 141 in existing files.)
Note: I've intentionally left intact other "variations" of the copyright
header, e.g. whether it says "Zebra", "Quagga", "FRR", or nothing.

The reading if unicast routes from the kernel acts subtly differently
between reading in the routes from the kernel on startup and
reading a new route or getting a response for a route.
Add startup flag(currently ignored) so that we can start
consolidating the functionality.
