Bug#749109: Bug#748679: Add autoconfiguration script for live-config

[intrigeri <intrigeri@debian.org>]

Hi Gaudenz,

meta:

 * I'm replying on #749109, as this part of the discussion is about
   code that's being added to live-config, not to broadcom-sta.
 * Daniel: sorry for the useless ping sent earlier this month on
   #748679, I was confused by the remaining tags left there
   after cloning.
 * I've tried to clarify the status of these two bug reports in the
   BTS, and the relationship between them, which seemed very confusing
   to me initially; sorry if I messed something up.

I've seen broadcom-sta support requested quite often on the Tails user
support channels, while I don't remember anything similar for other
drivers, so I say let's get the ad-hoc support for broadcom-sta in
first, hopefully in time for Jessie, and then we'll see if/how it can
be generalized. Fair enough?

Care to provide a patch that fixes these problems?
