Full MAC randomization is an important privacy-enabling feature. Some Android devices do this by default, and it is similar to the iOS8-like approach suggested in bug 1022444.

I think we can implement this feature in two steps:

- First we should introduce a pref (off by default, exposed in settings) to enable MAC randomization every time the WiFi interface comes up.

- Then we could add an option to force a constant MAC address for a given network, allowing users to activate the privacy feature while still being able to use networks with MAC-filtering.
