I used to use g_strv_length ((char **) p) instead, but that feels
ugly because it g_strv_length() is not designed to operate on
arbitrary pointer arrays.
When a VPN connection can't be activated we have to unexport and
dispose it. Commit f2182fbf9b ("core: don't emit double
PropertiesChanged signal for new active connections") removed the call
to nm_exported_object_unexport() in case of failure because the active
connection already gets unreferenced on failure.
However, an exported object can't be disposed until it's explicitly
unexported because GDBus code keeps a reference to it. The result was
that the active connection was kept alive and exported, but without
explicit references to it. As soon as the connection was unexported,
it was also automatically disposed, causing issues like:

The address change involves setting the link down which causes the supplicant
interface to change state and in turn another scan attempt. This could lead to
a loop in case of broken drivers that are not able to change the MAC address
iff the MAC address is attempted at each scan request.

If a configuration does not have a path it is because we are still
sending it to pacrunner or because we failed to do so. In both cases,
we have to remove the configuration from the list.
Fixes: 3ad89223d0
(cherry picked from commit fad2cf0721)
Don't try to remove the configuration if we haven't added it in the
first place, for example when the connection gets deactivated before
it completes or for slave connections without IP configuration.

If a VPN provides a proxy, we want to restrict the usage of that proxy
to URLs in the VPN domain. For all other connections, the proxy should
be used for all domains.
(cherry picked from commit b139552255)
Fix some issues in nm-pacrunner-manager.c:
- when adding a configuration through nm_pacrunner_manager_send(), we
kept an association between the interface name and the pacrunner
configuration object path, so that the configuration for that
interface could be removed later. Unfortunately not all
configurations have an interface associated, so we need a more
generic way to identify configurations. Introduce a new @tag
argument that serves as key to match configurations
- the interface name of the last pushed configuration was stored in
the manager private config and reused later; this could cause
issues when there are multiple outstanding D-Bus calls. The
interface is not needed anymore after the previous point.
- remove() didn't actually remove the configuration from the list

IEEE_80211_IE_VHT_CAP has zero hits searching the internet.
WLAN_EID_VHT_CAPABILITY is how the same define is called by
kernel's "include/linux/ieee80211.h".
Use the same name as kernel.
Also, collect the maximum of @max_rate.
Currently, 'nmcli dev wifi list' does not show the user any rates above
54Mbps. Now, we can check the IEs passed to NM from the wpa_supplicant,
pull the mcs rate and channel width information, and determine a maximum
possible data rate for 11n and 11ac APs.

on the state file, otherwise after restart the device is unmanaged.
