This commit makes the torture scripts a bit more RCU-independent by
changing RCU_KMAKE_ARG to TORTURE_KMAKE_ARG.  It also removes the
unnecessary export command.

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.

This commit adds the --kmake-arg to kvm.sh, which allows passing in
things like "V=1" to see the build commands, as well as enabling the
CROSS_COMPILE= make macro used for cross-building.

This commit adds the --no-initrd argument to kvm.sh, which permits
initrd to be contained in a root partition specified by the --bootargs
argument.  Without --no-initrd, the kernel build expects an initrd
directory in the same rcutorture directory that contains bin and configs.

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