The break value '-b' is not working properly:
- Every thread may hit the break value. This is expected for thread
number > 0 because thread number 0 sleeps every 16 iterations to give
the system time to breath. This delay may wrongly trigger as the break
value.
- If a thread hits the break value then it returns signaling "shutdown".
The main thread will then SIGTERM to each of the remaining threads.
This is a nop because this signal is blocked.
Send SIGUSR1 instead which is waited for.
While doing all of this, report the actual `max' value.

`oldtrace' is set for kernels prior 2.6.18. Remove "support" for them.
The alternative code (for new kernels) issues
prctl(0, [01]);
which is not valid the kernel returns an error. I have no idea what its
purpose is, remove it.

Now rt-tests won't build for archs other than x86/i386/ppc64 after oslat is
merged. Instead of failing the build, let's make it pass. However, whenever
oslat is executed, instead of running the real program, dump an error message,
so that people can try to implement the frc() function for it when there's a
real need for the new arch.

The makefile will run a shell command to determine the location of the
python libraries. If an error occurs, for example if the system doesn't
have python installed on it, undefine PYLIB
This prevents undesired side effects such as installing man pages for
utilities that will not be installed and does not interfere with other
conditionals such as if test -n "${PYLIB]"
Signed-off-by: John Kacur <jkacur@redhat.com>
Since the installation of get_cyclictest_snapshot.py is done if PYLIB
then we should only install the manpages then as well.

When the quiet option is used don't print all threads stats. The first
thread will pause every 16 cycles for 10000us. This will show up in
the max values for all other threads when the final results are
printed:
# signaltest -q -D 2s
T: 0 ( 4517) P: 0 C: 3121 Min: 5 Act: 8 Avg: 8 Max: 19
T: 1 ( 4518) P: 0 C: 3121 Min: 5 Act:10065 Avg: 639 Max: 10073
We could also remove the sleep but then the system gets fully loaded
by the test. Furthermore, we would keep the path pretty hot and that's
not ideal if one wants to test the eratic signal behavior. So only
consider the first thread for the stats.

oslat was initially a standalone program [1]. This patch merges oslat into
rt-tests repo.
This is a direct port of oslat v0.1.7 into rt-tests. It naturally bumps the
version to latest rt-tests version.
