porting scripts to python3

Hi,

Please review set of python3 fixes for oe scripts.

As most of the scripts are not covered by tests it was quite hard to test them. I tested only those which I know how to work with. It would be greate to have any help with testing.

The following changes since commit dcbfc72303d6782d9108538c830cf2ee7849bf59:

poky: Add Ubuntu 16.04 to tested/supported list since I run it myself (2016-06-02 10:37:05 +0100)

are available in the git repository at:
