dnsproxy and python 2.7

[Miika Komu]

The DNS proxy is not using python APIs in way compatible with python 2.7. Can we support both 2.6 and 2.7?

Did you check if the system hosts.py resembles the hosts.py in the HIPL respository?

Maybe we can use the pre-installed system files and make them a dependency for the hipdnsproxy instead of keeping own versions in the repository.

Yes, it's a modified version.

No we can't because HIPL hosts.py is a modified version of the system hosts.py.

Please note also the disclaimer in the commit:

Samuel told me that newer versions of hosts.py should likely work again
with dnsproxy. Somebody should doublecheck this. Getting rid of this
embedded library copy would be ideal.
