This adds a Make include file which most selftests can then include to get the run_tests logic. On its own this has the advantage of some reduction in repetition, and also means the pass/fail message is defined in fewer places. However the key advantage is it will allow us to implement install very simply in a subsequent patch. The default implementation just executes each program in $(TEST_PROGS). We use a variable to hold the default implementation of $(RUN_TESTS) because that gives us a clean way to override it if necessary, ie. using override. The mount, memory-hotplug and mqueue tests use that to provide a different implementation. Tests are not run via /bin/bash, so if they are scripts they must be executable, we add a+x to several.

Adds the set-2038 test which sets the time to near-edge cases like the start and end of the 32 bit epoch and checks that time behaves properly. There is also a dangerous mode, which lets the clock roll over past 2038 on 32bit systems, which on some older kernels will cause system hangs.

When ktest runs the console program as a child process, the parent and child share the same tty for stdin and stderr. This is problematic when using a libvirt target. The "virsh console" program makes a lot of changes to the tty settings, making ktest's output hard to read (carriage returns don't work). After ktest exits, the terminal is unusable (CRs broken, stdin isn't echoed). I think the best way to fix this issue would be to create a pseudoterminal (pty pair) so the child process would have a dedicated tty, and then use pipes to connect the two ttys. I'm not sure if that's overkill, but it's far beyond my current Perl abilities. This patch is a much easier way to (partially) fix this issue. It saves the tty settings before opening the console and restores them after closing it. There are still a few places where ktest prints mangled output while the console is open, but the output is much more legible overall, and the terminal works just fine after ktest exits.

Normal rcutorture checking overestimates grace periods somewhat due to the fact that there is a delay from a grace-period request until the start of the corresponding grace period and another delay from the end of that grace period to notification of the requestor. This means that rcutorture's detection of RCU bugs is less sensitive than it might be. It turns out that rcutorture also checks the underlying grace-period "completed" counter (displayed in Reader Batch output), which in theory allows rcutorture to do exact checks. In practice, memory misordering (by both compiler and CPU) can result in false positives. However, experience on x86 shows that these false positives are quite rare, occurring less than one time per 1,000 hours of testing. This commit therefore does the exact checking, giving a warning if any Reader Batch blows happen, and flagging an error if they happen more often than once every three hours in long tests.
