The CONFIG_PROVE_RCU_DELAY Kconfig parameter doesn't appear to be very
effective at finding race conditions, so this commit removes it.

[ paulmck: Remove definition and uses as noted by Paul Bolle. ]

This commit uses the standard software ploy of introducing another
level of indirection below the configs directory.  This allows each
torture-test suite to have its own set of Kconfig files, boot parameters,
and version-specific scripts.  Initially, we have only rcu, but lock
will follow soonish.

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