[kvm-unit-tests,v2,0/7] s390x: Add SIE library and simple test

Message

This is the absolute minimum needed to run VMs inside the KVM Unit
Tests. It's more of a base for other tests that I can't (yet) publish
than an addition of tests that check KVM functionality. However, I
wanted to decrease the number of WIP patches in my private
branch. Once the library is available maybe others will come and
extend the SIE test itself.

Yes, I have added VM management functionality like VM create/destroy,
etc but as it is not needed right now, I'd like to exclude it from
this patch set for now.

	* Added license and source identifiers to test_bit patch
	* Changed the way I test for sclp feature bits
