d7b323c2dd test-network: several cleanups
- fix verifiers in test_router_preference() to make them actually check
  if unnecessary routes are removed,
- stop radv in test_ndisc_vs_static_route() before checking if the static
  route is preserved even when the router sends a RA with zero lifetime,
- make verifiers in NetworkdIPv6PrefixTests stricter.

1ca180b994 network/nexthop: do not remove depending nexthops when a nexthop is removed
Previously, when a nexthop is removed, depending nexthops were removed, but
that's not necessary, as the kernel keeps them, at least with v6.11.

130d66956f test-network: reconfigure interface cleanly to drop previous DHCP lease and friends
Follow-up for 451c2baf30f50b95d73e648058c7c2348dbf0c31.

With the commits, reloading .network files does not release previously
acquired DHCP lease and friends if possible.

On graceful reconfigure triggered by the reload, the interface may
acquire a new DHCPv4 lease earlier than DHCPv6 lease. In that case,
the check will fail as it is done with the new DHCPv4 lease and old
DHCPv6 lease, which does not contain any IPv6 DNS servers or so.
So, when switching from no -> yes, we need to wait a new lease with DNS
servers or so. To achieve that, we need to clean reconfigure the interface.

52f46b77d7 network: reset 'configured' flags even if we keep DHCP lease and friends on reconfigure
Follow-up for 451c2baf30f50b95d73e648058c7c2348dbf0c31.

With the commits, reloading .network files does not release previously
acquired DHCP lease and friends if possible. If previously a DHCP client
was configured as not requesting DNS servers or so, then the previously
acquired lease might not contain any DNS servers. In that case, if the
new .network file enables UseDNS=, then the interface should enter the
configured state after a new lease is acquired. To achieve that, we need
to reset the flags.

With this change, the workaround applied to the test by the commit
451c2baf30f50b95d73e648058c7c2348dbf0c31 can be dropped.

451c2baf30 network: keep dynamic configurations as possible as we can on reconfigure
E.g. when a .network file is updated, but DHCP setting is unchanged, it
is not necessary to drop acquired DHCP lease.
So, let's not stop DHCP client and friends in link_reconfigure_impl(),
but stop them later when we know they are not necessary anymore.

Still DHCP clients and friends are stopped and leases are dropped when
the explicit reconfiguration is requested

21d9eeb5e6 networkd: Replace existing objects instead of doing nothing if they exist
Currently, if for example a traffic control object already exist, networkd
will silently do nothing, even if the settings in the network file for the
traffic control object have changed. Let's instead replace the object if it
already exists so that new settings from the network file are applied as
expected.

462be8c957 test-network: find routing policy rule by priority
We usually configure a test rule with a unique priority. Hence, finding
rule by priority reduces the lines of output, and we can debug easily.

Also print short comments on check. That's helpful when the check is
called several times.

936dec4337 test-network: do not pass '[detached]' to 'ip rule del'
That indicates the interface name in 'iif' or 'oif' cannot be resolved
when 'ip rule' command is invoked. That's natural when networkd fail to
remove rule but the corresponding interface is already removed.
To make not the residual rules interfere subsequent test cases, let's
ignore the flag and actually remove unwanted rules.

01420b2db5 network/ndisc: use router lifetime as one for redirect route
Previously, we did not set lifetime for redirect route, and redirect
routes were removed only when received a RA from the target address.
Thus, routes that redirect on-link addresses were never removed.

RFCs mention nothing about the lifetime of redirection. But the previous
implementation does not pass the IPv6 Core Conformance Tests.

This makes
- remember all received RAs and manage them by the sender address
  (previously, remembered only one with the highest preference),
- then use the router lifetime as one for redirect route,
- remove redirect route also when the router corresponds to the sender
  address is dropped (previously, considered only target address).

Note, even if we recieve a new RA, we do not update existing redirect
routes. The lifetime of the redirect route is updated only when a new
Redirect message is received.

Closes #32527.
