The existing test checks that the tinyproxy systemd service is confined. However
it is possible that this confinement is based on systemd launching tinyproxy
with the expected profile, rather than tinyproxy running under the profile due
to path-based attachment. So add an explicit check for this as well as requested

Some weirdnesses:
- The Perl abstraction specifies an ix execution mode for Perl, while my impression from the Python abstraction is that we shouldn't be specifying execution modes for the script interpreter in the abstractions. It's probably too late to change that though.
- Tcl apparently doesn't have an abstraction available. Given the way it's embedded into applications like ZNC, I'm assuming that Tcl doesn't have support files the way Python does.

Add AA profile for tnftp. This profile has been tested on the latest oracular tnftp version 20230507-2build3 which is also the latest upstream version. This profile limits the file downloads to common download directories and /tmp. It also cripples the "!" command denying access to network and allowing the execution of binaries located directories for which we deny write access. Any feedback is welcome.

Add AA profile for `socat`. This profile has been tested on the latest oracular socat version `1.8.0.0-4build3` and the latest upstream version `1.8.0.1`. I raised the PR and this profile has already been merged on the `roddhjav/apparmor.d` repo, [here](https://github.com/roddhjav/apparmor.d/pull/454). For now, I have added this profile in "extra", but let me know if you think otherwise, any feedback is welcome.

The current behavior of priority rules can be non-intuitive with
higher priority rules completely overriding lower priority rules even in
permissions not held in common. This behavior does have use cases but
its can be very confusing, and does not normal policy behavior
Eg.
priority=0 allow r /**,
priority=1 deny w /**,
will result in no allowed permissions even though the deny rule is
only removing the w permission, beause the higher priority rule
completely over ride lower priority permissions sets (including
none shared permissions).
Instead move to tracking the priority at a per permission level. This
allows the w permission to still override at priority 1, while the
read permission is allowed at priority 0.
The final constructed state will still drop priority for the final
permission set on the state.
Note: this patch updates the equality tests for the cases where
the complete override behavior was being tested for.
The complete override behavior will be reintroduced in a future
patch with a keyword extension, enabling that behavior to be used
for ordered blocks etc.

This profile deliberately does not use `abstractions/audio`, instead listing only the subset of the interfaces required to enumerate audio devices and control their volume, without the parts needed to actually send or receive audio from them. This could also be a useful basis for splitting `abstractions/audio` into finer-grained subcomponents.

This requires a runner with the tags: linux, x86_64, kvm. One needs to
be provisioned for the AppArmor project for the pipeline to function.
It is possible to run the same tests on SAAS runners offered by GitLab
but due to issue gitlab-org/gitlab-runner#6208 there is no way to expose
/dev/kvm on the host to the guest. Without this feature emulation works
but is rather slow as to be impractical.
Note that there's some overlap between the build-all job and spread that
might be avoided in the future. At present this is made more difficult
by the fact that the path where build-all job builds libapparmor is
stored internally by autotools. This prevents us from using GitLab
artifacts from moving the built files across to the spread testing jobs
without extra work.
In addition to adding the spread job, remove test-build-regression job.
This job is now redundant since the same operation is done when spread
builds and runs regression tests.

well as by running the upstream test suite with a brief hack to ensure it

The original patch adding priority to the set of prefixes failed to
update the prefix dump to include the priority priority field.
Fixes: e3fca60d1 ("parser: add the ability to specify a priority prefix to rules")

The priority field is only used during state construction, and can
even prevent later optimizations like minimization. The parser already
explcitily clears the states priority field as part of the last thing
done during construction so it doesn't prevent minimization
optimizations.
This means the state priority not only wastes storage because it is
unused post construction but if used it could introduce regressions,
or other issues.
The change to the minimization tests just removes looking for the
priority field that is no longer reported.

AppArmor denials and will fail if none was generated.

Introduce the EXPECT_DENIALS environment variable for profile tests.
Each line of EXPECT_DENIALS is a regex that must match an AppArmor
denial for the corresponding test, and conversely.
This ensures that problematic behaviors are correctly blocked and logged.
