[apparmor] [patch 0/5] regression tests: onexec improvements/fixes

[steve at nxnw.org]

In the course of trying to track down a couple of issues with the onexec
regression tests, I noticed that the tests had not been updated since
signal mediation support had been added, which prevented the tests from
working properly (the test program sends itself SIGSTOP to pause and
wait for the test driver to catch up, and the test driver sends it
SIGCONT to carry on). This patch set adds some clean ups that helped in
discovering this issue and adds the needed signal permissions to the
tests.

The lack of signal mediation extends back through the 2.9 series,
so at least patch [4/5] is nominated for 2.10 and 2.9 as well. I'd
prefer that the first four of the five get accepted for those releases
as well, but it's less crucial. (Since I didn't get a chance to convert
the tests or add any tests that make use of the new bit infrastructure
in the fifth patch, I don't yet see the point of bringing it back to
earlier branches.)
