With CONFIG_PREEMPT_DYNAMIC=y, the kernel builds with CONFIG_PREEMPTION=y
because preemption can be enabled at runtime. This prevents any tests
of Tiny RCU or Tiny SRCU from running correctly. This commit therefore
explicitly sets CONFIG_PREEMPT_DYNAMIC=n for those scenarios.

Tiny RCU's job is to be tiny, so this commit removes its RCU CPU
stall warning code. After this, there is no longer any need for
rcu_sched_ctrlblk and rcu_bh_ctrlblk to be in tiny_plugin.h, so this
commit also moves them to tiny.c.

The PROVE_RCU_REPEATEDLY Kconfig option was initially added due to
the volume of messages from PROVE_RCU: Doing just one per boot would
have required excessive numbers of boots to locate them all. However,
PROVE_RCU messages are now relatively rare, so there is no longer any
reason to need more than one such message per boot. This commit therefore
removes the PROVE_RCU_REPEATEDLY Kconfig option.

A number of the rcutorture test scenarios were not using the desired
Kconfig options because dependencies were preventing the selections in the
Kconfig-fragment files from being honored. This commit therefore updates
the Kconfig-fragment files to account for these changes in dependencies.

The RCU torture tests currently do not run any Tiny RCU scenarios for
CONFIG_DEBUG_OBJECTS_RCU_HEAD=y. This is a hole in the test, given
that someone might need this in real life and given that Tiny RCU uses
different callback-handling code than does Tree RCU. This commit
therefore enables this Kconfig option for scenario TINY02.

This commit adds CONFIG_PROVE_RCU_REPEATEDLY=y, which has been untested
for quite some time.

This commit updates TREE_RCU-kconfig.txt to reflect changes in RCU's
Kconfig setup. This commit also updates rcutorture's Kconfig fragments
to account for Kconfig parameters that are now driven directly off of
other Kconfig parameters.
The #CHECK# prefix tells the rcutorture scripts to take no action to try
to set the Kconfig parameter, but to check that it does in fact get set.
This is useful for verifying that Kconfig parameters that are supposed
to be automatically set do in fact get set to the required values.

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.
