Wifinina: transparently maintain wifi connection

This encapsulates the tedious task of maintaining connection with an access point. Now you don't have to have that boilerplate in your application code.

Especially useful for devices that can be moved and/or not always have stable WiFi connection. Supports multiple access points.

Plays nicely with http.Get and friends, see refactored example.

P.S. I've tried hard maintain backwards compatibility. Otherwise the API could, probably, be better.

Any suggestions for better name? HandleWifi is best I could come with. Alternative could be EnsureWifi. But they both so-so. ConnectWifi? But we not always connect, just verify there is active connection.

What is the current status of this PR? Is it still relevant? If so happy to help out apply the needed changes if needed :) (suffering from connection drops, this could help me solve it)

Hi Maartje! I believe this PR is so outdated that it's probably easer to create new, in a branch from current dev head than trying to rebase this one. Please, feel free to try and do that.

I am in progress on the first steps for some refactoring of the interfaces to all of the WiFi adaptors.

Will open an issue for discussion of that topic soon.

Closing now that netdev has landed.
