Convert postfix's master profile to use a named profile
(postfix-master) rather than the exec path match pattern. Adjust
postfix-common abstraction to take this into account. Rename profile
name in the profiles/apparmor/profiles/extras/ directory to match
the profile name.

Commit aa06528790 made @{sys} tunable
available by default.
Update profiles and abstractions to actually use @{sys} tunable for
better confinement in the future (when @{sys} becomes kernel var).
Closes LP#1728551
Also adjust the signal rules in the dovecot-common and apache2-common
abstractions to match the profile names, and to really do that
(peer=...{bin,sbin}... didn't work, the correct syntax would have been
peer=...\{bin,sbin\}...)
This fixes the regression introduced by !149 / commit
4200932d8f
Move @{sys} into tunables/kernelvars to make it readily available for
all profiles by default. In order to avoid duplicate variable
declaration, other tunable includes where modified accordingly.
Additionally, apparmor_api/is_enable has updated comment with regards to
@{sys} availability. tunables/sys is now marked as deprecated and should
not be used as it is noop, left only for backwards compatibility.
This is preparation for fixing bug:

Thanks to Christian Boltz for original idea to implement this in
non-breaking manner.
--log-facility option needs to have permission to open files.
Use '*' to allow using more files (for using more dnsmasq instances).

Use nvidia_modprobe named profile inside opencl-nvidia abstraction
Commit 8f9bd5b0 rightfully removed PUx
transition into nvidia-modprobe executable due to security concerns. To
overcome this, commit 327420b1 added
named nvidia_modprobe profile, which allows to use this abstraction
without requiring additional rules to make OpenCL work with NVIDIA
drivers.
Add rule to allow Px transition into nvidia_modprobe profile for
nvidia-modprobe executable.
I propose this for 2.13..master (opencl* are only available in 2.13...). Please check if nvidia_modprobe is already backported.

Add named profile to be used in application profiles for confining
potentially risky setuid application.

Currently, kde abstraction has rules relevant to Qt 3 and Qt 4
libraries, but are missing rules against latest Qt 5.
Include read-only Qt 5 abstraction to fix styling and similar issues for
software running on KDE 5 desktop.

Add @{uid} and @{uids} variables to allow migrating profiles in advance
while awaiting path mediation implementation, based on current user id,

Add rule allowing to execute /usr/bin/thunderbird.

Add qt5 writing abstractions
Qt-based applications stores QFileDialog (latest browsed directory) and
other shared user settings inside ~/.config/QtProject.conf. Currently
available qt abstraction only allows to read it (by design), so this
patch introduces abstraction that grants permissions for writing.
Relevant denies discovered with KDE Dragon Player:

In addition, added new qt-compose-cache-write abstraction as some applications wants to write compose cache. qt5 abstraction is appended with read-only rule (that's enough for LibreOffice using KDE file dialog).

Qt GUI applications that uses "platforminputcontexts"-class of plugins

KIconLoader uses ~/.cache/icon-cache.kcache, and it is opened in
read-write mode. Because access to it does not seem to be critical, and
read-only mode is not used, rules for accessing this cache is added to
it's own new "write" abstraction, instead of making kde abstraction more
permissive by default.
