Let's extend sigp reset testing and clean up the smp library as well.

GIT: https://github.com/frankjaa/kvm-unit-tests/tree/smp_cleanup

v3:
	* Added patch to introduce cpu loop in cpu setup
	* Added patch that removes cpu loops in favor of the previously introduced one
	* Fixed inline assembly for fpc dirtying
	* Moved cpu stop hunk from first into the second patch
	* Reworked patch #4 commit message and added a comment when waiting for PU

v2:
	* Added cpu stop to test_store_status()
	* Added smp_cpu_destroy() to the end of smp.c main()
	* New patch that prints cpu id on interrupt errors
	* New patch that reworks cpu start in the smp library (needed for lpar)
	* nullp is now an array
