[Qemu-ppc] [RFC 0/3] qtest hypercall support (s390x for now)

[Andreas Färber]

Hello,

Here's an initial throw at adding hypercall support to qtest.
This aims at making s390 virtio (and soon virtio-ccw) easily testable
during refactorings such as Fréderic's.
Depending on progress it might also be a route to add qtest support for the
individual virtio devices while waiting for a PCI libqos. :-)

qtest.c is being compiled once, so it cannot contain target-specific code.
I therefore add stubs qtest_hypercall_supported() and qtest_hypercall().
s390x then overrides them indicating support and implementing it. A dummy
test case is appending for verification that things compile and work so far.

One bug fix was already posted based on this testing; series is based on it.

I have not yet investigated what changes may need to be applied to the API
to make this work for sPAPR as well. Looking forward to feedback.

Regards,
Andreas
