The problem is seen where speed mismatch caused ECMP route
not being reflected with correct number paths (NHs).
During cold boot, some interface speed updated by zebra as
part of one shot timer and triggers interface add to clients.
In this case, ospf already have created interface (bond interface),
but speed was not updated, trigger to do interface speed change
as part of interface add, which will trigger all Router LSA to
use updated speed into cost calculation.
Ticket:CM-22170
Testing Done:
Bring up CLOS config with Spine and leafs. Leaf have CLAG pair,
with same VRR ip address.
At spine one of the bond connecting to leaf node was having
higher speed than the paired device, With this fix, at spine (DUT)
bond interface speed is equal from all peer nodes.

Currently, ospf external routers are part of struct
ospf_master which is not vrf aware ospf instance.
All ospf external routes are injected/leaked into all
vrfs.
Moved ospf external routes db to struct ospf to make
vrf aware, such one external routes learnt in one vrf
is not leaked into another vrf.

Validated follwoing sequence
- Create vrf1111
- Create ospf vrf1111 with no router-id
- Assign ip to vrf111
- ospf is assigned zebra assigned router-id which is vrf ip.
- upon remvoing vrf ip, the router-id retained as same until
ospfd restarted.

Performance tests showed that, when running on a system with a large
number of interfaces, some daemons would spend a considerable amount
of time in the if_lookup_by_index() function. Introduce a new rb-tree
to solve this problem.
With this change, we need to use the if_set_index() function whenever
we want to change the ifindex of an interface. This is necessary to
ensure that the 'ifaces_by_index' rb-tree is updated accordingly. The
return value of all insert/remove operations in the interface rb-trees
is checked to ensure that an error is logged if a corruption is
detected.

list_free is occassionally being used to delete the

This is a fallout from PR #1022 (zapi consolidation). In the early days,
the client daemons would allocate enough memory to send all nexthops
to zebra. Then zebra would add all nexthops to the RIB and respect
MULTIPATH_NUM only when installing the routes in the kernel. Now things
are different and the client daemons can send at most MULTIPATH_NUM
nexthops to zebra, and failure to respect that will result in a buffer
overflow. The MULTIPATH_NUM limit in the new zebra API is a small price
we pay to avoid allocating memory for each route sent to zebra.

Some differences compared to the old API:
* Now the redistributed routes are sent using address-family
independent messages (ZEBRA_REDISTRIBUTE_ROUTE_ADD and
ZEBRA_REDISTRIBUTE_ROUTE_DEL). This allows us to unify the ipv4/ipv6
zclient callbacks in the client daemons and thus remove a lot of
duplicate code;
* Now zebra sends all nexthops of the redistributed routes to the client
daemons, not only the first one. This shouldn't have any noticeable
performance implications and will allow us to remove an ugly exception
we had for ldpd (which needs to know all nexthops of the redistributed
routes). The other client daemons can simply ignore the nexthops if
they want or consult just the first one (e.g. ospfd/ospf6d/ripd/ripngd).

Pass pointer to pointer instead of assigning by return value. See
previous commit message.
To ensure that the behavior stays functionally correct, any assignments
with the result of a thread_add* function have been transformed to set
the pointer to null before passing it. These can be removed wherever the
pointer is known to already be null.

The way thread.c is written, a caller who wishes to be able to cancel a
thread or avoid scheduling it twice must keep a reference to the thread.
Typically this is done with a long lived pointer whose value is checked
for null in order to know if the thread is currently scheduled. The
check-and-schedule idiom is so common that several wrapper macros in
thread.h existed solely to provide it.
This patch removes those macros and adds a new parameter to all
thread_add_* functions which is a pointer to the struct thread * to
store the result of a scheduling call. If the value passed is non-null,
the thread will only be scheduled if the value is null. This helps with
consistency.
A Coccinelle spatch has been used to transform code of the form:
if (t == NULL)
t = thread_add_* (...)
to the form
thread_add_* (..., &t)
The THREAD_ON macros have also been transformed to the underlying
thread.c calls.
