Michal Privoznik	88957116c9	qemu: Use memory-backend-* for regular guest memory ... So far, Libvirt configures memory-backend-* for memory hotplug, possibly NUMA nodes and in a few other cases. This patch switches to constructing the memory-backend-* command line for all cases. To keep ability to migrate guests a little hack is used: the ID of the object is set to the one that QEMU uses internally anyways. These IDs are stable (first started to appear somewhere around v0.13.0-rc0~96) and can't change. In fact, this patch does exactly what QEMU does internally. The reason for moving the logic into Libvirt is that QEMU wants to deprecate the old style of specifying memory. So far, only x84_64 test cases are changed, because tests for other architectures use older capabilities, which still lack the QEMU_CAPS_MACHINE_MEMORY_BACKEND capability and they don't report the RAM ID.

Peter Krempa	3b8feb4793	qemu: capabilities: Replace aliased machine type by copy of the canonical machine ... The previous approac of just purging the alias combined with the fact that we filled in fake machine types in the test data meant that if a test case used an alias machine type such as 'pc' or 'q35' it would not properly resolve to the actual data returned by qemu. This started to be a problem since the CPU driver now looks at the default CPU reported with the machine type. This patch replaces the original approach of just removing the alias by replacing it with a copy of the machine type data which the type would alias to. This means that we are using the real data while we don't modify the test output after every qemu upgrade. Additionally this change will allow us to drop adding the fake machine types later. The test fallout is from actually excercising the CPU driver with actual data.

Andrea Bolognani	5b0dcbcdef	tests: Use DO_TEST_CAPS_*() for Intel IOMMU ... We can drop the intel-iommu-machine test case while doing so, since it is supposed to showcase how we generate different command lines for older QEMU versions and we can do that using a single input file now.
