the vrf_id parameter is replaced by struct vrf * parameter.
this impacts most of the daemons that look for an interface based on the
name and the vrf identifier.
Also, it fixes 2 lookup calls in zebra and sharpd, where the vrf_id was
ignored until now.

Solve issue #4198
Link-ID and Remote IP address must be set accordingly to the interface type
(Point-to-Point or Broadcast) from the neighbor information. However, this
information are only valid once the Network State Machine (NSM) is Full i.e.
when the adjacency is up. The original TE code only look to Interface State
Machine (ISM) change which not allow to collect valid neighbor information.
The patch move setup of Link-ID and Remote-IP TE parameters from
ospf_mpls_te_ism_change() to ospf_mpls_te_nsm_change() function.

1) stream allocation cannot fail
2) some warnings were removed when functions safely ignored
the calling parameters being wrong.
3) some warnings were removed when functions did not consider
the state as an error since we did not return an error code.

In all but one instance we were following this pattern
with ospf_lsa_new:
ospf_lsa_new()
ospf_lsa_data_new()
so let's create a ospf_lsa_new_and_data to abstract
this bit of fun and cleanup all the places where
it assumes these function calls can fail.

There is no need to check for failure of a ALLOC call
as that any failure to do so will result in a assert
happening. So we can safely remove all of this code.

When preforming CI test, CLI command 'no router ospf' followed by a
'router ospf' is performed to clean up the previous configuration.
Ospfd crash when configuring 'netwoark area'.
This is due to opsf_opaque_term() introduce in previous commit that cause this
crash. It remove not only Opaque LSA but also the list through the call to
'list_delete_and_null()' function. Same take place in 'ospf_mpls_te_term()',
'ospf_router_info_term()' and 'ospf_ext_term()' function.
New set of 'ospf_XXX_finish()' has been introduced to solve this issue while
keeping the possiblity to terminate properly the Opaque LSA and remove MPLS
LFIB entries set by Segment Routing.

This is an important optimization for users running FRR on systems with
a large number of interfaces (e.g. thousands of tunnels). Red-black
trees scale much better than sorted linked-lists and also store the
elements in an ordered way (contrary to hash tables).
This is a big patch but the interesting bits are all in lib/if.[ch].

Convert the list_delete(struct list *) function to use
struct list **. This is to allow the list pointer to be nulled.
I keep running into uses of this list_delete function where we
forget to set the returned pointer to NULL and attempt to use
it and then experience a crash, usually after the developer
has long since left the building.
Let's make the api explicit in it setting the list pointer
to null.
Cynical Prediction: This code will expose a attempt
to use the NULL'ed list pointer in some obscure bit
of code.

Multi-Instance OSPF configuration CLI would fail because
first client return error upon seeing qobj_index being 0.
With new marco generate new error code to return from each
instance (vtysh client) and if the command is intended for given
instance, its qobj_index would be nonzero and process the command
and push correct ospf context. Other instance would return the error.
On vtysh end, check all instance return an error log a message to a
file.
Testing Done:
Verfied various MI-OSPF configuration CLI with multi instances.
