The current implementation of TI-LFA computes link-protecting
repair paths (even when node protection is enabled) to have repair
paths to all destinations when no node-protecting repair has been
found. This may be desired or not. E.g. the link-protecting paths
may use the protected node and be, therefore, useless if the node
fails. Also, computing link-protecting repairs incurs extra
calculations.
With this patch, when node protection is enabled, link protecting
repair paths are only computed if "link-fallback" is specified in
the configuration, on a per interface and IS-IS level.

If LDP is miss configured in a setup and the router has LSPs with no remote
label, this code installs the LSP with a pop instruction of the top-level
label so the packet can be forwarded using IP. This is a best-effort
attempt to deliver labeled IP packets to their final destination instead of
dropping them. If this config is turned off the code will only install
LSPs that have a valid remote label.

As per the ospfv3 conformance test 24.3
SETUP: Configure DIface-0 with priority set to <hprty>.
ANVL: Establish full adjacency with DUT for neighbor Rtr-0-A on DIface-0.
DUT: Exchange all the <OSPF-DD> packets, during adjacency establish- ment.
ANVL: Verify that the received <OSPF-DD> packets contain: • one header of Link-LSA, originated by DUT.
ANVL: Send <OSPF-LSR> packet from neighbor Rtr-0-A to DIface-0 con- taining:
• One Request Tuple for Link-LSA originated by DUT.
ANVL: Listen (for upto 2 * <RxmtInterval> seconds) on DIface-0. DUT: Send <OSPF-LSU> packet.
ANVL: Verify that the received <OSPF-LSU> packet contains:
• •
one Link-LSA, originated by DUT, contains: Rtr Pri field set to <hprty>.
----------
When interface priority is changed Link LSAs should be tranmitted
with the priority set.
When the link priorty chanages, the drbdr algorithm is called, which
can change the state of the interface. But if the state does not
changes then LINK LSAs are not transmitted.
This PR fixes this issue. If the state is changed, then LINK LSAs
will anyways be tranmitted. But in case the state is not changed,
even in that case Link LSAs are tranmitted.

The previous method, using zassert.h and hoping nothing includes
assert.h (which, on glibc at least, just does "#undef assert" and puts
its own definition in...) was fragile - and actually broke undetected.
Just provide our own assert.h and control overriding by putting it in a
separate directory to add to the include path (or not.)

Initially the reading of the speed of an interface happened
upon interface creation and happened until the speed of a link
settled down to a single value. The speed of an interface
can also change as that a new optic can be inserted that
changes the speed, in which case FRR would see a interface
down (optic removal) and then a interface up (optic insertion).
In this case FRR would not treat this as an event that changed
the speed. Let's expand the checking a bit more.

When enabling TI-LFA the forward SPF for neighbors adjacent to the
PLR is computed. Later, when computing the PQ spaces, the reverse
SPF trees for those adjacent neighbors affected by the protected
interface are computed.
When node protection is enabled, TI-LFA link protection is run
immediately afterwards to compute repairs in case no
node-protecting backup path exists. In this second run, the
existing code tries to compute the reverse SPF tree for the same
node, without freeing the SPF tree of the prior run.
This patch fixes this by not computing the reverse SPF again, thus
avoiding a memory leak and an unnecessary SPF run.

Individual tests must not depend on each other. In particular, a test
can't be sure that the previous test config is applied or cleared.
It is definitely not true when a single test is executed, for example:
`test_bgp_auth.py::test_prefix_peer_remove_passwords`.
This commit makes all tests independent of each other. It also adds a
call to check_all_peers_established at the start of "remove_passwords"
tests to make sure that we not only block new peers with an incorrect
password, but also clean the existing peers.
