Add VRF support to the daemon. When the device we are activating is a
VRF or a VRF's slave, put routes in the table specified by the VRF
connection.

Also, introduce a VRF device type in libnm.

What's actually needed here is an explaination of how the license
applies along with the explanation where to find the full text.

Also, the libnm documentation was lacking the licensing information
altogether. Fix fixes it too.

After renaming the files, also rename all the content
to follow the "Wi-Fi P2P" naming scheme.

This only adds the new device type and simple peer list handling.

nm-initrd-generator scans the command line for options relevant to network
configuration and creates configuration files for an early instance of
NetworkManager run from the initial ramdisk during early boot.

For now, the device only exposes partial link status (not including
peers). It cannot create new links.

Check that we don't repeat the omission in future.
