Zbigniew Jędrzejewski-Szmek a811fb8b37 networkd: make neighbor_hash_func() handle the same data as neighbor_compare_func() 
In practice this probably makes little difference, because we only use AF_INET
and AF_INET6, but it's cleaner to use the same logic in both places.

Zbigniew Jędrzejewski-Szmek 67e05dd8cd networkd: use same order in _hash_func() and _compare_func() 
This makes it easier to see that the same data is handled in both cases.
No functional change.

Yu Watanabe 2aa7d367ec network: do not create default route for ipv4 link local addressing 
When nspawn container with private network starts, networkd creates
the default route for the interface. The route may cause problem on
the host side, and it can be created with DefaultRouteOnDevice= now.
Hence, this makes networkd not create the route implicitly any more.

Closes #13418.

Zbigniew Jędrzejewski-Szmek ea2552639b polkit: change "revert settings" to "reset settings" 
"reset" is more understandable. The verb is "revert", but it might actually be
better to have a description which uses different words instead of duplicating
the name of the command.

*We* control the sysctl setting. If the user configured IPv6, then we apply the

sysctl is disabled (i.e. ipv6 enabled) if we have IPv6 configured.

Replaces #13283.

Zbigniew Jędrzejewski-Szmek adfafd88b2 Revert "shared/conf-parser,networkd: EXTRACT_UNQUOTE|EXTRACT_RETAIN_ESCAPE → EXTRACT_UNQUOTE" 
This reverts commit 8a07b4033e.
The tests are kept. test-networkd-conf is adjusted to pass.

This fixes #13276. I think current rules are extremely confusing, as the
case in test-networkd-conf shows. We apply some kinds of unescaping (relating
to quoting), but not others (related to escaping of special characters).
But fixing this is hard, because people have adjusted quoting to match
our rules, and if we make the rules "better", things might break in unexpected
places.

Yu Watanabe ce158189a8 network: do not check deprecated flag in address_is_ready() 
Without this change, the address with PreferredLifetime=0 cannot be ready,
and thus, no consequent setting up process does not start.
The bug was introduced by 6aa5773.

Follow-up for b7ed5384ab.

Fixes #13341.

William A. Kennington III 0b1cd3e25a networkd: Routes should take the gateway into account 
Otherwise, changing the default gateway doesn't purge old gateway routes
left on the system during daemon restart. This also fixes removing other
foreign gateway routes that don't match the expected configuration.

Tested:
    Changed gateway addresses prior to the patch and they lingered on
    the system during each reconfiguration. Applied this patch and
    reconfigured gateways and other routes multiple times and it removed
    the foreign routes that had gateways that didn't match.
