[kvm-unit-tests,0/4] s390x: SIE cleanup 2

Time to deduplicate code before we copy it around even more.

Most problems originated from my desire to rapidly integrate SIE PV
support and as more and more people are using the SIE support it's
time to have a SIE library.

The SIE lib is by no means perfect. For that we might need a few more
iterations but it's good enough that we only need a bit of code in the
tests to get a guest going. This means we have a low entry to test
development which is my main goal.

  s390x: sie: Add sie lib validity handling
  s390x: lib: Introduce HPAGE_* constants
