Abstractions should not generally include deny rules as this can unduly
constrain profiles which include them due to the precedent matching rules
between deny vs allow rules. Also as per the comment, this is not required
for exo-open to work, so simply omit it from the abstraction for
now. Finally, in Ubuntu, the evince profile includes the exo-open
abstraction and this deny rule causes evince to fail to initialise
correctly as it then assumes it cannot use gvfs.

This is a manual backport of
728dbde5e4 by Mark Grassi
For the records: the inconsistent return length was introduced when
splitting run_tests() into two functions in
500cbf89a7
The inverse character set lists the characters it doesn't match. If
the inverse character set contains an oob then that is NOT considered
a match. So length should be one.
However because of oobs are handle not containing an oob doesn't mean
there is a match either. Currently the only way to match an oob is
via a positive express (no inverse matches are possible).

The snap_browsers abstraction requires more permissions
due to updates on snaps.
Some of the permissions are not required in older versions of
Ubuntu that use 2.12 and 2.13, but are introduced for unification

```
all dbus permissions,

I also propose a cherry-pick of this commit to 2.12, 2.13 and 3.0

As a short-term solution, we are adding a snap-browsers profile
which restricts what snaps opened by evince can do.
The long-term solution is currently not available, but could be
accomplished by using enhanced environment variable filtering/mediation
and delegation of open fds.

If apparmor_parser -N (in profiles_names_list()) fails,
aa-remove-unknown possibly gets an incomplete list of profiles in
/etc/apparmor.d/ and therefore might remove more profiles than it
should.
Replace the profiles_names_list() call with a direct apparmor_parser
call, and abort aa-remove-unknown if it exits with $? != 0
Before:
```
aa-remove-unknown -n
AppArmor parser error for /etc/apparmor.d/broken in profile /etc/apparmor.d/broken at line 1: syntax error, unexpected TOK_ID, expecting TOK_OPEN

Since the 'smb' machine is a container, the Apparmor denial ended up in the host's log:
```

```
It is the first time it occurs in years of use but it seems legitimate as:
1) this file is installed by the package
2) `git grep -F elasticsearch_mappings` in Debian samba's source shows many hits:
```

While only the `mdssvc` sub-dir could be authorized, the whole dir content seemed OK for read access anyway:

In 73e124d4fb I've upstreamed the `is_container_with_internal_policy()` function, but so far it was not used anywhere upstream. This is the missing bit.
I could trace the history of that patch back to 2012 (2.7.102-0ubuntu3):
* debian/apparmor.init: do nothing in a container. This can be
removed once stacked profiles are supported and used by lxc.
(LP: #978297)
Context: I lack both knowledge and motivation to keep maintaining this as part of the Debian delta. I'd rather see upstream, and in particular folks more knowledgeable than me about LXC/LXD, or with external motivation factors to work on this part of the stack, take care of it.
Note: Debian has similar code in its [sysvinit script](https://salsa.debian.org/apparmor-team/apparmor/-/blob/debian/master/debian/apparmor.init). I'm not touching that one.

GTK/QT apps need to read some config files in order to properly render their windows in a graphical session. There are some `qt5` abstractions already, but it looks like the `gtk` abstraction is missing.
The `*gtk*` rules are basically the location of the GTK config files I found on the internet when I was trying to compose this abstraction. Some of the paths are missing in Debian, but different distros can use (or were using) them. Since GTK apps use themes, the abstraction also include the whole `/usr/share/themes/` , `@{HOME}/.themes/` and `@{HOME}/.local/share/themes/` dirs. I'm not sure whether this should be tightened. The `.Xauthority` file is generally needed when you deal with GUI apps under Xserver. Also since all GUI apps redirect output/error to the `~/.xsession-errors` file, this file also was included here.

While we are here, also add -r (--no-run-if-empty, which also has no long equivalent for busybox) as we likely don't want to run anything if no profile were found

Both aarch64 and s390x have a bigger wtmp record size (16 bytes more

The byte position of the timestamp is also different on each

endian.
Note that this MR includes more things, like
* moving `get_last_login_timestamp()` to the new `apparmor/notify.py` file
* add unit tests for it
* add wtmp example files from various architectures, including a
hand-edited one claiming to be from 1999
* fixing a bug in `get_last_login_timestamp()` that unpacked `type` from
too many bytes - which accidently worked on x86_64
* detecting from which architecture the wtmp file comes (luckily the
timestamps are located at different locations)

'type' is a short (see "ut_type" in wtmp(5)), therefore only read two
bytes and unpack them as short. Afterwards read two padding bytes to
/dev/null.
This accidently worked on x86_64 because it's little endian, but will
fail on big endian architectures.

Some STATUS log events trigger a crash in aa-notify because the log
line doesn't have operation=. Examples are:
type=AVC msg=audit(1630913351.586:4): apparmor="STATUS" info="AppArmor Filesystem Enabled" pid=1 comm="swapper/0"
type=AVC msg=audit(1630913352.610:6): apparmor="STATUS" info="AppArmor sha1 policy hashing enabled" pid=1 comm="swapper/0"
Fix this by not looking at log events without operation=
Also add one of the example events as libapparmor testcase.

Merge branch 'fix-policy-cache-regression-tests' into 'master'
When using the system parser ${parser_config} will be empty and so if this
is unconditionally passed as an argument to the parser then this gets in
interpreted as the name of a file to be compiled and hence the parser just
prints:
File not found, skipping...
File not found, skipping...
File not found, skipping...
...
for all the aa_policy_cache tests - instead fix this to pass a single args
argument to the parser which will only include parser_config if it is not
empty.
This fixes the regression tests to run to completion without error when
USE_SYSTEM=1 is set.
