Hi Paolo and/or Thomas,

quite few tests have accumulated since the last pull request, so it's time for another one.

Changes in this pull request:

* Pierre contributed tests for his topology work. The QEMU related changes[1] aren't merged yet, so it's mostly skips right now. Since things seem to converge in QEMU and the kernel part[2] is merged, it makes sense to include this now in kvm-unit-tests.
* Pierre also contributed some fixes to the SCLP code when the size of the SCCV exceeds a page, e.g. when a certain number of vCPUs is exceeded. This also resolves an ugly loop of asserts() we can run into when SCLP fails early.
* Janosch contributed enhancements for the ultravisor host interface test, which fix some bugs
* Janosch also contributed more PV tests which cover certain vailidties the host can encounter when it tries to mess with the guest state, i.e. during IPL or SIE entry
* Finally, two small fixes from me fix compile with GCC 13 and a change in the runtime makes sure pv-host tests are only run when the respective tooling is available.
