This introduces a test case to check memory slots with overlapped regions on the guest address cannot be added. The cases checked are described in the block comment upon test_overlap_memory_regions() (see the patch 01).
I didn't see the need to calcute the addresses on compile/run-time, so I just left them hard-coded (remember: aligned 1M to work on s390x).
It works on x86_64, aarch64, and s390x.
The patch is based on queue branch.
Ah, I did some cosmetic changes on test_add_max_memory_regions() too. If it is not OK to be in a single patch...let me know.
