Previously, Wi-Fi scans uses polkit action
"org.freedesktop.NetworkManager.network-control". This is introduced
in commit 5e3e19d0. But in a system with restrict polkit rules, for
example "org.freedesktop.NetworkManager.network-control" was set as
auth_admin. When you open the network panel of GNOME Control Center, a
polkit dialog will keep showing up asking for admin password, as GNOME
Control Center scans the Wi-Fi list every 15 seconds.
Fix that by adding a new polkit action
"org.freedesktop.NetworkManager.wifi.scan" so that distributions can
add specific rule to allow Wi-Fi scans.

Extend the "ethernet.cloned-mac-address" and "wifi.cloned-mac-address"
settings. Instead of specifying an explicit MAC address, the additional
special values "permanent", "preserve", "random", "random-bia", "stable" and
"stable-bia" are supported.
"permanent" means to use the permanent hardware address. Previously that
was the default if no explict cloned-mac-address was set. The default is
thus still "permanent", but it can be overwritten by global
configuration.
"preserve" means not to configure the MAC address when activating the
device. That was actually the default behavior before introducing MAC
address handling with commit 1b49f941a6.
"random" and "random-bia" use a randomized MAC address for each
connection. "stable" and "stable-bia" use a generated, stable
address based on some token. The "bia" suffix says to generate a
burned-in address. The stable method by default uses as token the
connection UUID, but the token can be explicitly choosen via
"stable:<TOKEN>" and "stable-bia:<TOKEN>".
On a D-Bus level, the "cloned-mac-address" is a bytestring and thus
cannot express the new forms. It is replaced by the new
"assigned-mac-address" field. For the GObject property, libnm's API,
nmcli, keyfile, etc. the old name "cloned-mac-address" is still used.
Deprecating the old field seems more complicated then just extending
the use of the existing "cloned-mac-address" field, although the name
doesn't match well with the extended meaning.
There is some overlap with the "wifi.mac-address-randomization" setting.

Shared headers are all project-wide and internal API.
Currently we have the following:
General purpose:
- shared/gsystem-local-alloc.h: header-only, allocation macros
- shared/nm-dbus-compat.h: header-only, D-Bus related defines
- shared/nm-glib.h: header-only, glib compatibility defines
- shared/nm-macros-internal.h: header-only, utils
- shared/nm-shared-utils.[hc]: source and header, utils
- shared/nm-test*.[hc]: source and header, libnm testing utils
Special to NetworkManager repository:
- shared/nm-version-macros.h.in: header-only, version macros
- shared/nm-default.h: header-only, default-include
Now we add "shared/nm-common-macros.h" which is header-only, but non
general purpose.
I am running low on good names, considering all the shared/core/macros
utils headers. Still, I think "nm-common-macros.h" is appropriate.
