The rcutorture tests run by default range from using one CPU to using
sixteen of them. Therefore, rcutorture testing could be sped up
significantly simply by running the kernels in parallel. Building
them in parallel is not all that helpful: "make -j" is usually a
better bet. So this commit takes a new "--cpus" argument that
specifies how many CPUs rcutorture is permitted to use for its
parallel runs. The default of zero does sequential runs as before.
The bin-packing is minimal, and will be grossly suboptimal for
some configurations. However, powers of two work reasonably well.

Although the script name and arguments are logged in the results directory,
it is more convenient to see it in the output. This commit therefore
adds the output of this information.

Sometime problems can manifest themselves as unusually slow grace periods.
This commit therefore prints the number of rcutorture updates during the
test and the number per second. These statistics are harvested from the
config.out and qemu-cmd files, and are silently omitted if these files
are not available, as would be the case if there was a build failure or
a boot-time hang.

All of the rcutorture scripts has the usual GPL header, which contains
a long-obsolete postal address for FSF. To avoid the need to track the
FSF office's movements, this commit substitutes the URL where GPL may
be found.

The commit causes kvm.sh to invoke kvm-recheck.sh at the end of each
run, and causes kvm-recheck.sh to print only the name of the test, not
the full path to the corresponding Kconfig file.

Don't grab the configuration fragment from the configs directory because
it might well have been changed since the test was run. Instead, use
the ConfigFragment file that was placed in the results directory.

This commit adds the test framework that I used to test RCU under KVM.
This consists of a group of scripts and Kconfig fragments.
