The yang NB API does not handle the mpls configuration
on its leaf.
Add an mpls leaf to stick to the mpls configuration.
- true or false to mean if config
- not defined, means no config.

Add the support of Extended Admin-Group (RFC7308) to the zebra interface
link-params Traffic-Engineering context.
Extended admin-groups can be configured with the affinity-map:
> affinity-map blue bit-position 221
> int eth-rt1
> link-params
> affinity blue
> exit-link-params

The parent node of "vrf" MUST be non-NULL, so the check is unnecessary and
misleading. Otherwise, there will be a branch of NULL parent node, it makes
no sense, remove it.

The global vrf in zebra is always non-NULL. In general, it is bound to
default vrf by `zebra_vrf_init()`, at other times bound to some specific
vrf. Anyway, non-NULL.
So remove all redundant checkings for the returned value of
`zebra_vrf_get_evpn()`.
Additionally, remove the unnecessary check for `zvrf` in
`zebra_vxlan_cleanup_tables()`.

This is to fix the crash reproduced by the following steps:
* ip link add red type vrf table 1
Creates VRF.
* vtysh -c "conf" -c "vrf red"
Creates VRF NB node and marks VRF as configured.
* ip route 1.1.1.0/24 2.2.2.2 vrf red
* no ip route 1.1.1.0/24 2.2.2.2 vrf red
(or similar l3vni set/unset in zebra)
Marks VRF as NOT configured.
* ip link del red
VRF is deleted, because it is marked as not configured, but NB node
stays.
Subsequent attempt to configure something in the VRF leads to a crash
because of the stale pointer in NB layer.
Fixes#8357.

Zebra routing tables are not controlled by the user and can not be
created/deleted manually. Current NB create/destroy callbacks are
incorrectly implemented because instead of creating/deleting the RIB
they are only checking for it's existence. YANG model should reflect
the real situation.

There are places in the code where function nb_running_get_entry is used
with abort_if_not_found set to true during the config validation stage.
This is incorrect because when used in transactional CLI, the running
entry won't be set until the apply stage, and such usage leads to crash.

If a route-map in zebra has `set src X` and the interface
X is on has not been configured yet, we are rejecting the command
outright. This is a problem on boot up especially( and where I
found this issue ) in that interfaces *can* and *will* be slow
on startup and config can easily be read in *before* the
interface has an ip address.
Let's modify zebra to just warn to the user we may have a problem
and let the chips fall where they may.

As part of PR 6758 vrf vni converted to transactional cli.
Handle a scenario where vrf is not created yet (inactive) and vni
is mapped to the inactive vrf.
Testing Done:
bharat(config-vrf)# do show vrf
vrf vrf1 id 11 table 1001
vrf vrf5 inactive (configured)
bharat(config)# vrf vrf5
bharat(config-vrf)# vni 5005
bharat(config-vrf)# do show vrf vni
VRF VNI VxLAN IF L3-SVI State Rmac
vrf5 5005 None None Down None
bharat(config-vrf)# no vni 5005
bharat(config-vrf)# do show vrf vni

The northbound configuration callbacks should now print error
messages to the provided buffer (args->errmsg) instead of logging
them directly. This will allow the northbound layer to forward the
error messages to the northbound clients in addition to logging them.
NOTE: many callbacks are returning errors without providing any
error message. This needs to be fixed long term.

Walk over RIB tables using keys.
The first RIB table will be IPV4/unicast (table-id 254)
will be fetched.

afi-safi and table id as the keys.
remove mandatory true statement from the leaf which
is part of the list key.

Having a fixed set of parameters for each northbound callback isn't a
good idea since it makes it difficult to add new parameters whenever
that becomes necessary, as several hundreds or thousands of existing
callbacks need to be updated accordingly.
To remediate this issue, this commit changes the signature of all
northbound callbacks to have a single parameter: a pointer to a
'nb_cb_x_args' structure (where x is different for each type
of callback). These structures encapsulate all real parameters
(both input and output) the callbacks need to have access to. And
adding a new parameter to a given callback is as simple as adding
a new field to the corresponding 'nb_cb_x_args' structure, without
needing to update any instance of that callback in any daemon.
This commit includes a .cocci semantic patch that can be used to
update old code to the new format automatically.
