libupnp ABI change notice


I plan to update libupnp to 1.8.3 which comes with an ABI bump.
The libthreadutil library is also dropped in this new release.

I will rebuild the dependent applications

On a side note, I've also updated the current branches to the latest
1.6.25 bugfix release.
Please report any issue in the related bodhi tickets
