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.

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.

Unfortunately similar to bwrap unshare will need the mediate_deleted

This was tested using the test-tinyproxy.py script from qa-regression-testing as
well as by running the upstream test suite with a brief hack to ensure it
invokes tinyproxy with aa-exec -p tinyproxy first.

tinyproxy does not need all of nameservice, nameservice-strict is
sufficient. Thanks to @cboltz for the suggestion.

Add comments to the profile to explain the use of the local override if the

Add rules to allow tinyproxy to bind to privileged ports and access files even
when run as unprivileged/privileged users when using non-standard
configurations. As suggested by @rlee287.

Gtk applications like Firefox request write access to the file
`/run/user/1000/dconf/user`. The code in `dconf_shm_open` opens the file
with `O_RDWR | O_CREAT`.

Starting with Python 3.8, you can use the PYTHONPYCACHEPREFIX environment
variable to define a cache directory for Python [1]. I think most people would set
this dir to @{HOME}/.cache/python/ , so the python abstraction should allow
writing to this location.

From LP: #2085377, when using ip netns to torrent traffic through a
VPN, attach_disconnected is needed by the policy because ip netns sets
up a mount namespace.

Instead of denying everything here, enumerate just the bits that are required
and also deny access to display devices since that is not actually needed by
rygel itself.

mx-extract also uses these parts of gstreamer so allow it as well as for the

This allows access to the freedesktop.org mime info amongst others which is
