Commit e253c28 ("tests: Fix how qom-test is run") introduced
$(qtest-generic-y) and used it for check-qtest-% target, but did not
update check-report-qtest-%. This causes check-report-qtest-aarch64.xml
target to fail with a gtester usage error for lack of test arguments.
Fix this by adding $(qtest-generic-y) in check-report-qtest-%.

Setting the parent bus of a device increases its ref count, which we
ultimately want to level out. However it is only safe to do so after the
last reference to the device in local code, as qom-set or similar operations
might decrease the ref count.
Therefore move the object_unref() from pc_new_cpu() into its callers.
The APIC operations on the last CPU in pc_cpus_init() are still potentially
insecure, but that is beyond the scope of this code movement.

The current implementation depends on a configure-time generated list of
block modules. When any of them is absent, module_load() emits a warning.
This is suboptimal because extracting code to modules was mainly done to
allow separate packaging of modules with intrusive dependencies. Absence
of optional packages then leads to absence of modules and an error
message, which users may recognize as new and report as error.

CPU address spaces touching load and store helpers as well as the
movement of (almost) all fields from CPU_COMMON to CPUState have led to
a noticeable increase of CPU() usage in "hot" paths for both TCG and KVM.
While CPU()'s OBJECT_CHECK() might help detect development errors, i.e.
in form of crashes due to QOM vs. non-QOM mismatches rather than QOM
type mismatches, it is not really needed at runtime since mostly used in
CPU-specific paths, coming from a target-specific CPU subtype. If that
pointer is damaged, other errors are highly likely to occur elsewhere
anyway.
Keep the CPU() macro for a consistent developer experience and for
flexibility to exchange its implementation, but turn it into a pure,
unchecked C cast for now.
