dd5a6c2e0a Merge Include profile name in error message on directory exec
... to make the error message more helpful.

Inspired by https://gitlab.com/apparmor/apparmor/-/issues/285

I propose this patch for 3.1 and master.
(3.0 uses a different variable name - if we want it there, it needs a slightly different patch.)

b904fe78a7 Merge Make BaseRule a proper abstract base class
This closes #277 by introducing the following changes:
1. `BaseRule` was made a "proper" abstract base class in that it now enforces that subclasses implement all abstract methods.
2. As a consequence of this change, `BaseRule` can no longer be directly instantiated; tests were changed accordingly.
3. These test changes led to test failures, the reason being that many rule methods hardcoded class names, breaking inheritance. I made a commit to address this.
4. Once tests were passing, code coverage regressed due to the fact that there was now effectively-unreachable code in abstract instance methods. This code, which was only raising `NotImplementedError`s, was removed. I say "effectively-unreachable" here because it could be reached by calling `super()` via a subclass.
5. There are three "bonus" commits as well; one bug fix, one typo fix, and one cleanup.

Closes #277

Catch PermissionError when trying to write a profile
... and re-raise it as AppArmorException so that only the actual error
(without a backtrace) gets displayed.

7f6ffd33b2 Merge Rename BaseRule parse() and _parse() methods
As discussed in !920, this MR renames BaseRule's `parse()` and `_parse()` methods to `create_instance()` and `_create_instance()`, respectively. It then removes the `selection_to_rule_obj` function from `apparmor.aa`, which is now an unnecessary alias for the renamed public method.

Prevent crash on log entries for non-existing profile
If audit.log contains entries for a profile that doesn't exist (for
example when working with a log file from another system), skip these
log entries instead of crashing.

Reproducer (crashes without this patch):

    aa-logprof -f <(echo 'type=AVC msg=audit(1661739121.578:77893): apparmor="DENIED" operation="open" profile="no_such_profile" name="/run/" pid=33099 comm="no" requested_mask="r" denied_mask="r" fsuid=1000 ouid=0')
