There were a few problems with the way we output "debug" messages.
The first is that we used DEBUG() which is defined when NDEBUG is
not defined, but NDEBUG will never be defined for kselftests
because it relies too much on assert(). The next is that most
of the DEBUG() messages were actually "info" messages, which
users may want to turn off if they just want a silent test that
either completes or asserts. Finally, a debug message output from
a library function, and thus for all tests, was annoying when its
information wasn't interesting for a test.
Rework these messages so debug messages only output when DEBUG
is defined and info messages output unless QUIET is defined.
Also name the functions pr_debug and pr_info and make sure that
when they're disabled we eat all the inputs. The later avoids
unused variable warnings when the variables were only defined
for the purpose of printing.

Currently vcpu_args_set is only implemented for x86. This makes writing
tests with multiple vCPUs difficult as each guest vCPU must either a.)
do the same thing or b.) derive some kind of unique token from it's
registers or the architecture. To simplify the process of writing tests
with multiple vCPUs for s390 and aarch64, add set args functions for
those architectures.

The naming VM_MODE_P52V48_4K is explicit but unclear when used on
x86_64 machines, because x86_64 machines are having various physical
address width rather than some static values. Here's some examples:
- Intel Xeon E3-1220: 36 bits
- Intel Core i7-8650: 39 bits
- AMD EPYC 7251: 48 bits
All of them are using 48 bits linear address width but with totally
different physical address width (and most of the old machines should
be less than 52 bits).
Let's create a new guest mode called VM_MODE_PXXV48_4K for current
x86_64 tests and make it as the default to replace the old naming of
VM_MODE_P52V48_4K because it shows more clearly that the PA width is
not really a constant. Meanwhile we also stop assuming all the x86
machines are having 52 bits PA width but instead we fetch the real
vm->pa_bits from CPUID 0x80000008 during runtime.
We currently make this exclusively used by x86_64 but no other arch.
As a slight touch up, moving DEBUG macro from dirty_log_test.c to
kvm_util.h so lib can use it too.

KVM: s390: add kselftests
This is the initial implementation for KVM selftests on s390.
This is the same as vm_vcpu_add_default, but it also takes a
kvm_vcpu_init struct pointer.

This allows aarch64 tests to run on more targets, such as the Arm
simulator that doesn't like KVM_ARM_TARGET_GENERIC_V8. And it also
allows aarch64 tests to provide vcpu features in struct kvm_vcpu_init.
Additionally it drops the unused memslot parameters.

VM_MODE_P52V48_4K is not a valid mode for AArch64. Replace its
use in vm_create_default() with a mode that works and represents
a good AArch64 default. (We didn't ever see a problem with this
because we don't have any unit tests using vm_create_default(),
but it's good to get it fixed in advance.)

This code adds VM and VCPU setup code for the VM_MODE_FLAT48PG mode.
The VM_MODE_FLAT48PG isn't yet fully supportable, as it defines the
guest physical address limit as 52-bits, and KVM currently only
supports guests with up to 40-bit physical addresses (see
KVM_PHYS_SHIFT). VM_MODE_FLAT48PG will work fine, though, as long as
no >= 40-bit physical addresses are used.
