TL;DR: update AppArmor to 3.0.0 + some post-release fixes

Long version:

- add utils-fix-hotkey-conflict.diff to fix a hotkey conflict in
de, id and sv translations (and fix the test) (MR 675)
- add extra-profiles-fix-Pux.diff to fix an inactive profile -
prevents a crash in aa-logprof and aa-genprof when creating a new
profile (MR 676)

- update to AppArmor 3.0.0
- introduce feature abi declaration in profiles to enable use of
new rule types (for openSUSE: dbus and unix rules)
- support xattr attachment conditionals
- experimental support for kill and unconfined profile modes
- rewritten aa-status (in C), including support for new profile modes
- rewritten aa-notify (in python), finally dropping the perl
requirement at runtime
- new tool aa-features-abi for extracting feature abis from the kernel
- update profiles to have profile names and to use 3.0 feature abi
- introduce @{etc_ro} and @{etc_rw} profile variables
- new profile for php-fpm
- several updates to profiles and abstractions (including boo#1166007)
- fully support 'include if exists' in the aa-* tools
- rewrite handling of alias, include, link and variable rules in
the aa-* tools
- rewrite and simplify log handling in the aa-logprof and aa-genprof
