[$] iwd: simplifying WiFi management

It has been nearly 13 years since Jeff Garzik proclaimed that Linux was 'proving its
superiority in the area of crappy wireless (WiFi) support'.
Happily, the situation has improved somewhat since then, but that doesn't
mean that things can't get better yet. During the Embedded Linux
Conference portion of the 2018
Open Source Summit Europe, Marcel Holtmann described the work being
done to create iwd, a new system
for configuring and managing WiFi
connections. If this project has its way, future users will have little room
for complaint about how WiFi works on Linux systems.
