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.

Some environments require some variation on "make defconfig" to initialize
the .config file.  This commit therefore adds a --defconfig argument to
allow this to be specified.  The default value is of course "defconfig".

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 uses configcheck.sh from within configinit.sh, replacing the
imperfect inline expansion that was there before.

This commit drops no-longer-needed diagnostics from the output.  Some of
them are retained in logfiles, in case they are ever needed.

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