Version 2 takes into consideration that different versions of python

The functionality in get_cpuinfo_mhz.sh has been incorporated into
determine_maximum_mpps.sh, so it can safely be removed.
The queuelat is built from the rt-tests suite Makefile, and the old
Makefile in the queuelat directory can be removed.

This patch changes the default behavior of the Makefile to install
man pages without compression. This allows distribution build systems to
use the kind of compression they wish to use without the Makefile
getting in the way.
It is still possible to compress the man pages using the Makefile, for
example
make MAN_COMPRESSION=gzip
or
make MAN_OMPRESSION=bzip2

Without setting the thread affinity, the scheduler will move the
threads around which will lead to spikes. Since any proper realtime
application will use thread affinity, let's pin down the threads to
CPUs.

A common task is to parse the provided cpumask from the command
line. Add a helper which uses libnuma. Since we don't want to add
unnecessary dependencies for tests which don't need this helper create
a new library containing the NUMA bits.

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]"

Since the installation of get_cyclictest_snapshot.py is done if PYLIB
then we should only install the manpages then as well.

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.

We announced way back in 2015 that compiling without the NUMA libs was
no-longer supported, but we left the bits in there for you to do it
anyway.
Since this is not supported, and is broken now anyway, let's remove the
cruft.
Of course running on non-NUMA machines should still work fine.

Currently the man pages are unconditionally gzip compressed. However, users
might want to use something else such as bzip2 or none.
When using package management systems it makes sense to use no compression at
all, as the package system might chose the appropriate one. Therefore, introduce
MAN_COMPRESSION. This variable is handling how the compression is done. Default
is gzip.

currently does not cause source to be built using the intended
toolchain, instead will use the host toolchain.
CC & AR are not updated with CROSS_COMPILE value since they are
predefined make variables (with default cc & ar respectively) combined
with the fact that CC & AR variables are updated in the makefile only if
not already defined due to the usage of '?='.

NUMA users should have long ago stepped up to libs that have
numa_parse_cpustring_all(). Make this the default so that we can include
isolated cpus in the affinity string.
If there are any NUMA users or distros left that have old libraries that
don't have numa_parse_cpu_string_all(), and only numa_parse_cpu_string()
they can compile like this
make HAVE_PARSE_CPUSTRING_ALL=0
