This patch add support to IPVLAN interface. IPVLAN is a driver for a
virtual network device that can be used in container environment to
access the host network. IPVLAN exposes a single MAC address to the
external network regardless the number of IPVLAN device created inside
the host network. This means that a user can have multiple IPVLAN
devices in multiple containers and the corresponding switch reads a
single MAC address. IPVLAN driver is useful when the local switch
imposes constraints on the total number of MAC addresses that it can
manage.
The setting was missing from the script. The patch is adding it and also
regenerates the docs.
Fixes: 5426bdf4a1 ('HSR: add support to HSR/PRP interface')
The HSR DBus metadata was defined properly but not exported on the libnm
library properly. This was causing that clients were not showing the HSR
devices.
Fixes: 5426bdf4a1 ('HSR: add support to HSR/PRP interface')
The "StartLimitIntervalSec" and "StartLimitBurst" directives should be
in the [Unit] section instead of the [Service] one.

When using the netdev datapath, we wait for the link to appear in
different steps:
1. initially, in act_stage3_ip_config() connects to platform's
"link-changed" signal to detect when the TUN interface appears;
2. when the interface appears, _netdev_tun_link_cb() schedules
_set_ip_ifindex_tun() in a idle handler;
3. _set_ip_ifindex_tun() checks if the link is ready (e.g. if the MAC
address is correct) and in that case it reschedules stage3, which
will move forward with the activation;
4. if the link is not ready in _set_ip_ifindex_tun(), the function
connects again to platform's "link-changed" signal to react to link
changes;
5. after the link changes and it is ready, _netdev_tun_link_cb()
reschedules stage3, which moves forward with the activation;
With the current implementation it is possible that after step 2, if
act_stage3_ip_config() runs because it was already scheduled, it
registers again to the "link-changed" event; then when
_set_ip_ifindex_tun() is invoked it will hit assertion:
nm_assert(!priv->wait_link.tun_link_signal_id);
Fix this by preventing that the signal gets registered again after
step 2.

Add option --all to distros_support.py to show all the NM versions that
are being actively used by any active distro. This will be useful to
decide what stable branches are we interested into actively backporting
fixes and which ones we're not.
Passing a version number of NetworkManager to this new script, it prints
what distros are using that NM version and generates a new content for
.gitlab-ci/config.yml.
Automatically generating the config.yml content is useful because we can
easily update what distros we test in the CI and the Tier that they
belong, depending on what version of NM do they ship and whether they
have reached EOL or not.
Important: when generating a config.yml for an stable branch, not for
main, it must be generated from main. This is because we are not going
to keep distros-info.yml up to date in all branches, only in main.
The string array returned by nm_l3_config_data_get_searches() is not
NULL-terminated; we need to pass the exact length to
nm_utils_buf_utf8safe_escape_strv() instead of letting the function
scan for the NULL terminator.
Fix the following error reported by valgrind:
Conditional jump or move depends on uninitialised value(s)

Fixes: 522a7d6baf ('nm-ip-config: escape searches when exposing to dbus')
Previously, when a connection was configured with search domains
that contained non-ASCII characters, GLib would try to parse the
search name as UTF-8, and an assertion would fail (which meant
that if NM was running with fatal assertions, it would crash).
Expose the search domains only as an escaped string to avoid this.
Previously, the "edit" or "delete" buttons were clickable even
if there were no available connections, which was not expected
and caused an assertion to fail when clicked. This is because
the connections list could contain connections that were later
filtered out and not displayed in the final list, but the check
did not take this into account.
Make it so that the buttons are clickable only if we *actually*
have any available connections to edit or delete.

When a connection with ipv4.method=auto (DHCP) is configured with
ipv4.link-local=enable we were leaving the link-local address forever,
but this is not correct according to RFC3927[1] which says:
a host SHOULD NOT have both an operable routable address and an IPv4
Link-Local address configured on the same interface.
This adds a new mode that is more compliant, which only sets an IPv4
link-local address if no other address is set (through either DHCP lease
or ivp4.addresses setting)
Closes#1562

Add a new l3cfg DatFlag to specify that a given l3cd has a
non-link-local IPv4 set.
This will be used to enable or disable IPv4LL automatically in fallback
mode.
Move the static _ip4_address_is_link_local() check to a new global
nm_platform_ip4_address_is_link_local() helper so we can check if
an IPv4 is link local in other files
When lease is lost we would keep the DHCP state to READY, but we are
trying to get a new lease at this point so it is closer to PENDING.
Note this does not change how the device is displayed in `nmcli device`,
a connection with an expired lease is still displayed as `connected`.
When handling event TIMEOUT, "acd_data->probing_timeout_msec" needs to
be always initialized before jumping to "handle_start_probing:";
otherwise, an assertion failure is triggered at:
static void
_l3_acd_data_timeout_schedule_probing_restart(AcdData *acd_data, gint64 now_msec)
{
...
nm_assert(acd_data->probing_timeout_msec > 0);
Even if the ACD data is already in state PROBE, that doesn't mean that
the timeout is already initialized because the PROBE state can also be
reached from a INSTANCE_RESET event; and depending on the previous
state "acd_data->probing_timeout_msec" could be uninitialized.

The code handling options with supposes, that options
are split by `=`, which is not the case. This fixes the following:
```
nmcli -f ipv4.ad\t\t
nmcli -f ipv4.ad=ipv4.addresses
nmcli --field ipv4.ad\t\t
nmcli --field ipv4.ad=ipv4.addresses
```
Using options with values separated with `=` remains broken,
but this change doesn't affect it:
```
nmcli --field=ipv4.ad\t\t
nmcli --field=ipv4.ad
```
Also, `man` and `usage` uses `--color auto|yes|no`,
not `--color=auto|yes|no`. So, this fix should be sufficient.

Managed type = managed is a bit unclear, because all managed types are
for devices that are managed, but with different levels. Managed type =
managed could be interpreted as other types are unmanaged. Change it to
managed type = full.
