The rcutorture scripting handles the CONFIG_*_TORTURE_TEST Kconfig
options specially, and therefore greps them out of the Kconfig-fragment
files.  Unfortunately, a poor choice of grep pattern means that the
CONFIG_RCU_TORTURE_TEST_SLOW_CLEANUP, CONFIG_RCU_TORTURE_TEST_SLOW_INIT,
and CONFIG_RCU_TORTURE_TEST_SLOW_PREINIT Kconfig options are also grepped
out, preventing rcutorture from using them.  This commit therefore fixes
the offending grep pattern to focus only on the CONFIG_*_TORTURE_TEST
Kconfig options.

This commit sets the executable bit on test scripts config2frag.sh
and kvm.sh.  Since #!/bin/bash is set in all the scripts, this commit
also drops it from all usage lines because the scripts can now all be
invoked directly.

Some of the scripts encode a default /bin/sh shell. On systems which use
dash as default shell, these scripts fail as they are bash scripts. I
encountered this while testing the sprintf() changes on a Debian system
where dash is the default shell.

This commit changes all such uses to use bash explicitly.

The torture tests need to set specific values for their respective
Kconfig options (e.g., CONFIG_LOCK_TORTURE_TEST), and must therefore
filter any conflicting definitions from the Kconfig fragment
file.  Unfortunately, the code in kvm-build.sh was looking only for
CONFIG_RCU_TORTURE_TEST.  This commit therefore handles the general case
of CONFIG_[A-Z]*_TORTURE_TEST.

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.
