[GIT PULL] runtime verifier: Updates for v6.19

Linus,

Runtime verifier updates for v6.19:

- 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 for more validations

Add more validations for 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

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 of errors

If the reactors 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.

- Convert core RV code to use lock guards and __free helpers

This completely removes goto statements.

- Fix compilation if !CONFIG_RV_REACTORS

Fix the warning by keeping LTL monitor variable as always static.
