Some netlink-facing code used for evpn/vxlan programming was
being run in the dataplane pthread, but accessing zebra core
datastructs. Move some additional data into the dataplane
context, and use it in the netlink path instead.

Move neighbor programming to the dataplane; remove
old apis; remove some ifdef'd use of direct netlink
code points, using neutral values outside of the netlink-
specific files.

The `destination` field of the connection structure was used to store
the broadcast address, if the connection was not p2p. This multipurpose
is not very evident and the benefits over calculating the bcast address
on the fly minimal.

Update the stats displayed by 'show zebra dplane' - some
counters had been added but not displayed. Also include
the new counters for evpn macs.

Initial data struct and api changes to support EVPN MAC
updates via the dataplane subsystem (no handlers yet).

This is mostly relevant for Solaris, where config.h sets up some #define
that affect overall header behaviour, so it needs to be before anything
else.

Field vrf_id is replaced by the pointer of the struct vrf *.
For that all other code referencing to (interface)->vrf_id is replaced.
This work should not change the behaviour.
It is just a continuation work toward having an interface API handling
vrf pointer only.
some new generic functions are created in vrf:
vrf_to_id, vrf_to_name,
a zebra function is also created:
zvrf_info_lookup
an ospf function is also created:
ospf_lookup_by_vrf
it is to be noted that now that interface has a vrf pointer, some more
optimisations could be thought through all the rest of the code. as
example, many structure store the vrf_id. those structures could get
the exact vrf structure if inherited from an interface vrf context.

Some updates may be the result of a plugin's actions - such
as an async notification. Add accessor so that we can
identify that an update was generated by a plugin.

Add a callback called at start time, once the dplane pthread
and thread_master are available. The callback is optional.

No need to check for non-null ctx at this point in the
function as that it has already been derefed.

Start using the dataplane for interface-address programming,
on netlink platforms. Other platforms just stubbed at this

Use const in the accessors for pseudowire nhlfe data; pull

The master thread handler is really part of the zrouter structure.
So let's move it over to that. Eventually zserv.h will only be
used for zapi messages.

The sequence number used should be unique and increase by 1
for netlink commands. This will allow the code to match
up batched commands to actual requests, so that we can signal
the failure correctly back.
So start the movement and tracking of sequence numbers as
an atomic uint32_t in zebra_router. Modify the dataplane
code to start tracking contexts from this value.
In future commits we will move more of the sequencing
data into using this value.

Adding infra to zebra dplane to support LSP updates. Add
kernel api for LSP updates that uses a dataplane context; add
stub apis for netlink, bsd, and 'null' kernel paths. Add
version of netlink mpls update code that takes a dplane
context struct instead of a zebra lsp struct.
