Subject: [PATCH 1/9] gnetworkmonitornm: Set a GError properly on an error
handling path
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
All the other initialisation failure paths set a GError, but this one
didn’t. Set a GError to avoid breaking the invariant that returning
FALSE should always have a GError set.

Subject: [PATCH 2/9] Handle an UNKNOWN NetworkManager connectivity as NONE
nm_conn_to_g_conn already handles UNKNOWN like NONE (returning
G_NETWORK_CONNECTIVITY_LOCAL in both cases). So in sync_properties
we should also set new_connectivity to G_NETWORK_CONNECTIVITY_LOCAL
for both NM_CONNECTIVITY_UNKNOWN and NM_CONNECTIVITY_NONE.
This has the added benefit that when NetworkManager returns the network
connectivity is UNKNOWN, we set network_available to FALSE as it should
be. Previously, there were cases in a laptop with no network access,
that g_network_monitor_get_network_available returned true, which was
wrong and is also fixed with this commit.

Subject: [PATCH 3/9] gnetworkmonitornm: Fix network available detection
The network-available property can be asserted by querying the NMState
describing the current overval network state, instead of the
NMConnectivityState. The advantage of the NMState is that is reflects
immediately the network state modification, while the connectivity
state is tested at a fixed frequency.

Subject: [PATCH 4/9] gnetworkmonitornm: Consider NM_STATE_CONNECTED_SITE to be
available
`NM_STATE_CONNECTED_SITE` is documented to mean that a default route is
available, but that the internet connectivity check failed. A default
route being available is compatible with the documentation for
GNetworkMonitor:network-available, which should be true if the system
has a default route for at least one of IPv4 and IPv6.

signal
Use the org.freedesktop.DBus.Properties interface to listen
to PropertiesChanged signals on /org/freedesktop/NetworkManager.
NetworkManager used to provide its own legacy PropertiesChanged
signal, but that was dropped in
https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/merge_requests/853
This requires NetworkManager >= 1.2 (2016)
