Subject: [PATCH] Fix IPv6 scope (bsc#1108557)

Fix ipaddress imports

Remove unused import

Fix ipaddress import

Fix unicode imports in compat

Override standard IPv6Address class

Check version via object

Isolate Py2 and Py3 mode

Add logging

Add debugging to the ip_address method (py2 and py3)

Remove multiple returns and add check for address syntax

Remove unnecessary variable for import detection

Remove duplicated code

Remove unnecessary operator

Remove multiple returns

Use ternary operator instead

Remove duplicated code

Move docstrings to their native places

Add real exception message

Add logging to the ip_interface

Add scope on str

Lintfix: mute not called constructors

Add extra detection for hexadecimal packed bytes on Python2. This cannot be detected with type comparison, because bytes == str and at the same time bytes != str if compatibility is not around

Fix py2 case where the same class cannot initialise itself on Python2 via super.

Simplify checking clause

Do not use introspection for method swap

Fix wrong type swap

Add Py3.4 old implementation's fix

Lintfix

Lintfix refactor: remove duplicate returns as not needed

Revert method remapping with pylint updates

Remove unnecessary manipulation with IPv6 scope outside of the IPv6Address object instance

Lintfix: W0611
