Check the delta between vivid-overlay and xenial

[Łukasz Zemczak]

Since the train became more self-service than before, and counting in all the approved exceptions, there's a risk that the delta between the overlay and xenial got a bit out-of-hand. We would need to get this delta analysed.

I created a script checking the package versions in the overlay for vivid and got the following output - unparsed for now:

Improving the script to handle different cases, will not paste any new results - will send a final comment with the final report after parsing.

[Łukasz Zemczak (sil2100)]

Did some digging into the latest results and came up with such a list. The situation doesn't look as bad as it seems, but of course some projects might have been missed. Most of the packages that have a big delta between xenial and the overlay are caused by the ABI-problems with gcc5 - some of those, like trust-store and location-service, try to get back to dual-landability already. Developers for those projects need to be made aware of the situation.
