WireGuard in systemd-networkd

[Jason A. Donenfeld]

Hi folks,

Thanks to the wonderful work of Jörg Thalheim, WireGuard is now
supported inside systemd-netword's .netdev files. The syntax should be
pretty similar to wg(8). Expect for this to be released as part of the
next release of systemd, where you'll then be able to read the man
pages for using it.

Next up - anybody interested in providing support for NetworkManager?

Jason
