get_iflink_speed() returns UINT32_MAX when the speeds is unknown.
Routing daemons (at least ospfd) interprets it as the high value.
Return errors in get_iflink_speed() to avoid the confusion.

The following configuration creates an infinite routing leaking loop
because 'rt vpn both' parameters are the same in both VRFs.

> no bgp network import-check

> address-family ipv4 unicast
> network 28.0.0.0/24
> rd vpn export 10:12
> rt vpn both 52:100
> import vpn
> export vpn
> exit-address-family

The previous commit has added a routing leak update when a nexthop
update is received from zebra. It indirectly calls
bgp_find_or_add_nexthop() in which a static route triggers a nexthop
cache entry registration that triggers a nexthop update from zebra.
Do not register again the nexthop cache entry if the BGP_STATIC_ROUTE is
already set.

If 'bgp network import-check' is defined on the source BGP session,
prefixes that are defined with the network command cannot be leaked to
the other VRFs BGP table even if they are present in the origin VRF RIB
if the 'rt import' statement is defined after the 'network <prefix>'
ones.
When a prefix nexthop is updated, update the prefix route leaking. The
current state of nexthop validation is now stored in the attributes of
the bgp path info. Attributes are compared with the previous ones at
route leaking update so that a nexthop validation change now triggers
the update of destination VRF BGP table.

"if not XX else" statements are confusing.
Replace two "if not XX else" statements by "if XX else" to prepare next
commits. The patch is only cosmetic.

If 'bgp network import-check' is defined on the source BGP session,
prefixes that are defined with the network command cannot be leaked to
the other VRFs BGP table even if they are present in the origin VRF RIB.
Always validate the nexthop of BGP static routes (i.e. defined with the
network statement) if 'network import-check' is defined on the source
BGP session and the prefix is present in source RIB.

IRDP client (rdisc) was deleted from iputils more than 2 years ago. It's
time to drop IRDP, but first let's stop building and including it in the
packages by default to see if anyone will be complaining.

We may actually need to send CLI commands to mgmtd and another daemon at
the same time, for example, if this daemon is not mgmtd-converted. The
only daemon this exception protects is staticd. But we don't actually
need any configuration commands in staticd, so just remove the exception
and don't install unnecessary commands to staticd.

When the daemon is partially mgmtd-converted, it receives configuration
from vty and mgmtmd simultaneosly. This configuration must be
synchronized.

When duplicating nodes, we should always keep flags, especially the
LYD_NEW flag that indicates not validated data. This allows to select a
new choice's case without the need to explicitly remove the existing one.

These commands don't really provide any functionality. VRF is associated
with netns automatically based on its name, and it's not possible to
associate VRF and netns with different names with these commands:
- When trying to assosiate a VRF with an already existing netns with a
different name:
`NS /run/netns/test is already configured with VRF 1(test)`
- When trying to assiciate a VRF with a non-existing netns, so they
become linked once the netns is created:
`Invalid pathname for /run/netns/test: No such file or directory`
- When doing "no netns" to unlink the netns and link it back to the same
VRF:
`VRF 1 is already configured with VRF test`
- When doing "no netns" to unlink the netns and link it to another VRF:
`Can not associate NS 4294967295 with NETNS /run/netns/test`
As shown above, not a single usecase is working. We can't remove them
completely to preserve backwards-compatibility, so just make them empty.
The main reason for this change is not to spend a lot of time trying to
figure out how to convert them to northbound.
