The mqueue tests were using the previous format which was specific for
capabilities. The qual= prefix should be used instead.

dbus-broker requires some modification of the test suite. In summary:
* refactor to support starting and stopping both dbus and dbus-broker.
* Make it so we can run the tests on each, where appropriate
* skip unrequested reply and eavesdrop tests for dbus broker because they are not supported.

DBus Broker was enabled for the dbus_message and dbus_service
regression tests.
The dbus_eavesdropping test does not run with dbus-broker because
eavesdropping was deprecated in favor or monitoring, so new tests for
the "BecomeMonitor" method need to be added.
The dbus_unrequested_reply test is also not supported by dbus-broker,
therefore the tests are skipped.

Commit 8cf3534a5 ("tests regression: fix failure on older versions of
Make") from https://gitlab.com/apparmor/apparmor/-/merge_requests/639
was incorrectly applied, including the `+` prefixes from the proposed
patch. This causes the sysctl syscall() checks to not correctly be
applied and results in a mismatch of expectations in the
syscall_sysctl.sh test script, causing it and the testsuite to fail.
Thus, remove the bogon `+` characters from the Makefile, to make
USE_SYSCTL be set correctly.

The test "eavesdrop (confined w/o dbus perms)" was failing for the
wrong reason. While it should fail because it is missing dbus rules, it
was actually failing because it didn't have the required unix rule.
The error message was:
"FAIL: Failed to open connection to "session" message bus: Failed to open socket: Permission denied"
Corresponding audit log:

After the change, the error message is:

This is a debug patch that unconditionally sets a profile debug flag
if mqueue rules are present. It should not be present in merged

that is desired.

Add read rule to allow reading @{pid}/comm.
The kernel will allow for a couple of debug flags on a profile that
can be used to trigger debug messages for only profiles/labels that
have the flag set. Add basic support for these to the parser.

Based on what was done in the parser, replicate the logic
so it can be used in the python tools.

Setns is used to associate to an existing user namespace, so the
kernel security hook for user namespace creation is not called.
The restriction for setns is that it should have the capability
sys_admin.

This MR closes#286.
Strings with only invalid escape sequences were prefixed with an `r`. Strings containing both valid and invalid escape sequences were handled on a case-by-case basis, as simply changing to a raw string breaks valid escape sequences.
Closes#286

This MR closes#276.
In b150c40ed1, I removed the big comment at the top of `BaseRule` stating what methods have to be implemented by subclasses. This was out-of-date, had redundant method descriptions, and was no longer necessary now that `BaseRule` has an `ABCMeta` metaclass and auto-enforces the implementation of abstract methods.
`rule._logprof_header_localvars()` implementations weren't consistent, so I took the opportunity to clean them up in db99138f56. Return types differed, the presence of empty `header` lists differed, how size-two collections were returned differed, etc.
Otherwise, this MR closely follows the discussion in #276.
Closes#276
