It's better to do any performance measurement in post processing. This
keeps the test scripts simpler and splits the tasks clearly.
While at it, remove the unused cyclictest format parsing from
parse_rt_tests_results since it is not used anymore.

Start a background process to create load on the system while running
the test.

cyclictest output is meant for interactive terminals. On dumb
terminals, it creates lots of noise resulting in massive logs.
Use quiet output (-q) to silence and just print a summary at the end
of the test.

Update all rt-tests with the current upstream v1.4 release.
The x86_64 and armeabi architecture binaries are build using a Debian
stretch root filesystem.
arm64 binaries were build using a Debian buster root filesystem.
The command to build the binaries is: "CLFAGS=-static make"

The nanosleep option has been removed from cyclictest in commit
9d2c9edd8694 ("cyclictest: make clock_nanosleep as default and add
option for POSIX timers.").

Add duration command line to cyclictest. rt-tests v1.4 added to many
tools the option '-D'/'--duration'.
This makes the math how long the program is suppose to run
max with --loops and --interval far simpler.
Remove the loops argument in favor of duration.
While at it also add the missing affinity option in the usage output.

The test should fail if the max value is larger then the expected
MAX_LATENCY has been observed.
MAX_LATENCY value is board and kernel specific, which means the
job needs to set it accordingly.
Unfortunatly, we need to add a slightly more complex parser for
finding the numbers and add the pass/fail flag.

Don't run cyclictest at priority 99 because the highest priority is
for the high priority kernel tasks. The highest user land priority
is 98.
Furthermore, we should make sure the threads are not migrated (set the
affinity). Also all memory should preallocated (mlockall) before
starting the measurement.
Additional the recommended why to sleep is to use clock_nanosleep
which is not default.
And finally also set the interval to 1000us which most -rt maintainers
are using. This allows to compare the result easier.

In my case, my system has already get cyclictest installed, so just use
it.

Other tests from rt-tests already have this tag. With this patch, we
will be able to filter them easily.
