Drop the "accel" property from MachineState, and instead desugar
"-machine accel=" to a list of "-accel" options.
This has a semantic change due to removing merge_lists from -accel.
For example:
- "-accel kvm -accel tcg" all but ignored "-accel kvm". This is a bugfix.
- "-accel kvm -accel thread=single" ignored "thread=single", since it
applied the option to KVM. Now it fails due to not specifying the
accelerator on "-accel thread=single".
- "-accel tcg -accel thread=single" chose single-threaded TCG, while now
it will fail due to not specifying the accelerator on "-accel
thread=single".
Also, "-machine accel" and "-accel" become incompatible.

Make the current "powernv" machine an abstract type and derive from it
new machines with specific CPU models: power8 and power9.
The "powernv" machine is now an alias on the "powernv9" machine.

Pass around the QTestState, so that we can finally get rid of the
out-of-favor global_qtest variable in this file, too.
Signed-off-by: Thomas Huth <thuth@redhat.com>
qtest_init() creates a new QTestState, and leaves @global_qtest alone.
qtest_start() additionally assigns it to @global_qtest, but
qtest_startf() additionally assigns NULL to @global_qtest. This makes
no sense. Replace it by qtest_initf() that works like qtest_init(),
i.e. leaves @global_qtest alone.

commit 1ed9c8af50 ("target/ppc: Add POWER9 DD2.0 model information")
deprecated the POWER9 model v1.0.

We have several callers that were formatting the argument strings
themselves; consolidate this effort by adding new convenience
functions directly in libqtest, and update some call-sites that
can benefit from it.
Note that the new functions qtest_startf() and qtest_vstartf()
behave more like qtest_init() (the caller must assign global_qtest
after the fact, rather than getting it implicitly set). This helps
us prepare for future patches that get rid of the global variable,
by explicitly highlighting which tests still depend on it now.

A couple of tests for the work-in-progress 'powernv' machine type attempt
to test on POWER9 CPUs. However the POWER9 CPU support is incomplete and
this doesn't really work. In particular the firmware image we have
currently assumes the presence of the SDR1 register, which no longer exists
on POWER9. We only got away with this so far, because of a different bug
which added SDR1 to POWER9 even though it shouldn't be there.
For now, remove POWER9 testing of powernv, POWER8 testing will do for now
until the POWER9 support is more complete.

Add a couple of tests on the XSCOM bus of the PowerNV machine for the
the POWER8 and POWER9 CPUs. The first tests reads the CFAM identifier
of the chip. The second test goes further in the XSCOM address space
and reaches the cores to read their DTS registers.
