at the time of ospf deamon init.

Currently, only default area parameter is used for initialization, but
we should use area parameters with interfaces address as well.

Move ospf initialization to the actual place where it is created.
We don't need to do that every time "router ospf" is entered.
Also remove a couple of useless checks that can never be true.

OSPFD sends ARP proactively to speed up convergence for /32 networks
on a p2p connection. It is only an optimization, so it can be disabled.
It is enabled by default.

On startup of both zebra and ospfd. If ospfd has not
received a valid router-id *but* has received interface
data, interfaces will not be turned on in the state
machine. When ospf finally receives a valid router-id
it would never actually kick the state machine into
action for those interfaces it has been configured for.
Modify ospf on router id changes, *if* the old
router id was INADDR_ANY *and* the interface is
operative *and* the oi->state is ISM_Down, give
it the old kick in the patooeys

Default originate with route-map was broken. Routemap
was not getting applied for redistribute route but was
getting applied default route itself. No default route
was originated even when routemap was satisfied.

Fix a number of library and daemon issues so that daemons can
call frr_fini() during normal termination. Without this,
temporary logging files are left behind in /var/tmp/frr/.

Well, "obviously" this condition block is pointless, since
ospf_router_id_update is called afterwards unconditionally...
(And even if it were needed, it would need to go in ospf_get too.)

Neither ospf_external_lsa_originate_timer() nor
ospf_default_originate_timer() are actually timers. They're only
executed on router-ID changes to refresh a particular LSA type.

no router ospf triggers to cancel all threads
including read/write (receive/send packets) threads,
cleans up resources fd, message queue and data.
Last job of write (packet) thread invoked where the
ospf instance is referenced is not running nor
the socket fd valid.
Write thread callback should check if fd is valid and
ospf instance is running before proceeding to send a
message over socket.

Testing Done:
Performed the multiple 'no router ospf' with the fix
in topology where the crash was seen.
Post fix the crash is not observed.

The shutdown of ospf was causing crashes because the shutdown
was calling a ALL_LIST_ELEMENTS_RO macro and modifying the
underlying data structures. Switch to using ALL_LIST_ELEMENTS.
This is caused by this change:

ospfd: Cleanup ospf->redist and ospf->external on shutdown
Effectively my original testing for this only had one external
route and as such we would not have a crash here. It only
showed up after multiple externals have been introduced.

These two data types were written to handle redistribute

allocated to these if we are doing redistribution.

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.

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.
