rv: Add explicit lockdep context for reactors (2025-11-11 13:18:56 +0100)

----------------------------------------------------------------
Summary of changes:

* Adapt the ftracetest script to be run from a different folder, this
uses the already existing OPT_TEST_DIR but extends it further to run
independent tests, then add an --rv flag to allow using the script for
testing RV (mostly) independently on ftrace.
* Add basic RV selftests in selftests/verification to validate things
like available/enabled monitors and reactors. This could have caught
the bug introducing kernel panic solved above. Tests use ftracetest.
* Convert react() function in reactor to use va_list directly and use a
central helper to handle the variadic arguments. Clean up macros and
mark functions as static.
* Add lockdep annotations to reactors to have lockdep complain if they
are called from improper context. Useful to develop new reactors. This
highlights a warning in the panic reactor that is related to the
printk subsystem and not to RV.
