bf2054d963 Merge utils: tests: cleanups and allow profile skipping in test-logprof and test-minitools
The utils cannot parse some profile constructs yet, so allow some profiles to be ignored in those tests.

df0358062d utils: test: expand mechanism for ignoring profiles in tests
The utils cannot parse some of the newer profile constructs yet, so
generalize a pre-existing mechanism for skipping profiles to use that mechanism in the other tests that need it

0e8377cde9 Merge test-translations: include "ignore" in exec prompts + make debugging hotkey conflicts easier
This is a follow-up of adding the "ignore" option to exec prompts in
https://gitlab.com/apparmor/apparmor/-/merge_requests/1543

To make future handling of hotkey conflicts easier,
- display all hotkey conflicts at once instead of erroring out at the first conflict.
- display all options involved in a hotkey conflict to make fixing it easier.

Since 1543 was picked into 4.1, I propose the same for this MR.

472181ae75 Merge profiles: fix sbuild to work with the unprivileged_unshare profile
sbuild is an unconfined profile allowing it to bypass the unprivlieged
user namespace restriction.

unconfined profiles use a pix transition which means that when the
unprivileged_unshare profile is enabled, the binaries in an unconfined
profile calling unshare will cause a transition to the unprivileged_unshare
profile.

This will break sbuild because it needs capabilities within the
user namespace.

However we cannot just add a x transition rule to unconfined profiles, as
the transitions won't be respected. Instead, we have to make the profile
a default allow profile and add a transition that will override
the default pix transition of allow all.

We have to add the attached_disconnected and mediated_deleted flags
because sbuild is manipulating mounts.

792aca634e Merge Perl typemap for const char* subprofiles[]
The original plan was to have a minimal subset for Perl excluding the stuff requiring language-dependent typemaps, but it turns out that there was only one thing that required that, and it was simple enough to copy over from the SWIG repo itself. This MR contains the single non-language-generic part of the SWIG updates.

8711c7754b Merge tests: provide better output on failures
When a test fails because of an unexpected success (XFAIL), do not display the empty error log as that may confuse the reader just as it had confused the author.

In addition, when something legitimately fails then display tail of trace log as that may show some useful information.

783f012074 Merge tunable: add int variable
This PR only adds the digit `@{d}` and integer `@{int}` variables.

It provides two improvements from the use of the `[0-9]*` glob:
- security: the glob means "a digit followed by anything but `/`", whereas `@{int}` means "up to 10 digits"
Next to the
- stability: using glob in path with `x` can expose to path conflict, removing the glob fixed a lot of issues.

These variables are used by a lot of abstractions that could be upstream here from apparmor.d (PR will follow). It is an import from 33681e14f2/apparmor.d/tunables/multiarch.d/system where other similar variables are in use: `@{hex}`, `@{rand}`, `@{word}`, `@{u8}`, `@{u16}`, `@{u64}`, `@{int2}...@{int64}` ...
They also all could be upstreamed here.

 - specifying messages for `static_assert` declarations (required up until C23, was accepted as a compiler extension on the systems I had tested this on previously)
 - removing label-followed-by-declaration instance (also a C23 feature supported as extension)
