A SR policy matches a BGP nexthop based on the IP address of
the nexthop and the color of the route (color may be assigned
to routes using a route-map).
The order of events (BGP route arrival, route-map definition,
policy and candidate-path definition) should not affect the
matching/mapping.
These changes add tests for:
- removing/adding BGP route after policy and routemap are
defined and held constant
- changing route map color to be different from policy color,
and then changing back to match
after each change, the policy should be observed to be in effect
unchanged from before, i.e., the route's nexthops should reflect
the matching SR policy.

In the last step of this test, r1's link to r2 is shut down but
both routers stay connected through a multi-hop LDP session. That
happens because r1 and r2 have a targeted adjacency created by
the pseudowire. The test then checks whether the pseudowire is
still up, using an alternate path for nexthop resolution.
Everything's fine except for the fact that LDP GTSM (aka
ttl-security) is enabled by default. This means that messages sent
over a multi-hop session are not delivered. In the case of this
test, it can prevent PW-Status notifications from being delivered,
which in turn can prevent the pseudowire from coming back up.
Fix the test by disabling GTSM so that LDP multi-hop sessions can
work normally. This is in accordance with RFC6720 which mentions
that GTSM should be disabled (statically or dynamically) for
multi-hop sessions.

When you have a static route with multiple different admin
distances there exists a chance that route will have been
installed multiple times due to system load when inserted
at about the same time. If this is the case then the
verify_rib function can and will select the wrong route
that happens to have a nexthop group that is still installed.
Modify verify_rib to ensure that the route that is going to
be looked at for nexthop correctness is the actual installed
route, not a previous version of it.

The sporadic failures were happening because, under heavy load,
the r4 router could form an OSPF adjacency with r3 a few seconds
before doing the same with r2. In that interim, LDP could establish
a neighborship with r2 going through r3 (instead of connecting
directly). That would cause all label mappings received from r3
to be ignored since they can't be mapped to the routes' nexthops
received from zebra, causing all sorts of test failures. None of
this is erroneous behavior as LDP simply follows the IGP.
The fix consists of updating the test to ensure all expected OSPF
adjacencies fully converged before proceeding to the LDP checks.

Lots of tests call verify_rib that takes a list of routes that
need to be verified in some fashion. This verify_rib functionality
will try up to 12 seconds before failing the check that zebra

Unfortunately the verify_rib code was not looking to see if
the route was queued for installation and was then allowing
tests to immediately do subsuquent steps that depended on
that route actually being installed sometimes causing tests
to fail.

Firstly, *keep no change* for `hash_get()` with NULL
`alloc_func`.
Only focus on cases with non-NULL `alloc_func` of
`hash_get()`.
Since `hash_get()` with non-NULL `alloc_func` parameter
shall not fail, just ignore the returned value of it.
The returned value must not be NULL.
So in this case, remove the unnecessary checking NULL
or not for the returned value and add `void` in front
of it.
Importantly, also *keep no change* for the two cases with
non-NULL `alloc_func` -
1) Use `assert(<returned_data> == <searching_data>)` to
ensure it is a created node, not a found node.
Refer to `isis_vertex_queue_insert()` of isisd, there
are many examples of this case in isid.
2) Use `<returned_data> != <searching_data>` to judge it
is a found node, then free <searching_data>.
Refer to `aspath_intern()` of bgpd, there are many
examples of this case in bgpd.
Here, <returned_data> is the returned value from `hash_get()`,
and <searching_data> is the data, which is to be put into
hash table.

a) Remove the retry mechanism to continue looking for 75%
of the time for pim code.
This alone saves a bunch of time in tests that use lib/pim.py
Effectively all the times given for retry are already long
enough. Additionally some tests are gathering data with
the expectation that they will not find data so the entire
time is being taken up in retry's. Extending the retry
mechanism makes this even worse. This is especially bad
for pim in that keep alive timers are counting down and
state can be removed due to excessive time waiting.
b) Reduce verify verify_multicast_traffic from 40 seconds
to 20 seconds to gather traffic data.
A bunch of tests are doing this:
a) gather pre test start traffic data( taking about 70
seconds to run, because a bunch of time it was looking
for data that does not exist yet)
b) run a change to introduce a different traffic flow
c) gather post test traffic data ( taking about 70
seconds to run )
Why does this matter? Tests were iterating through
all the different routers looking for traffic flow
as well as different mroute state. This is against
the keepalive timer of 210 seconds. It does not take
long before the stream can be removed and the test is
still looking for data that is no longer there due
to state timeout.
The multicast_pim_sm_topo3/test_multicast_pim_sm_topo3.py
test reduced run time from 398 seconds to 297 seconds.
Greatly reducing keepalive timeout problems.

When link-param is enabled for a given interface, TE metric is automatically
assigned to the metric of the interface. However, the metric of the interface
could be unassigned and keep the default value equal to 0. Thus, if the TE
metric is not explicitely modified within the `link-param metric` statement,
TE metric remains set to 0 which is not a valid value especially when
computing constrainted path.
This patch changes the assignement of the default value of the TE metric.
It is set to the metric of the interface only if the latter is not equal to 0.
TE topotests for OSPF and IS-IS have been adjusted accordingly.
