This series implements a few RTAS hypercalls in tests/libqos

This started as an attempt of implementing hot unplug qtests for the
sPAPR machine but I've found a few issues that will require more time
- CPU hot unplug: for some reason the machine freezes after the
callback is returned.
- LMB hot unplug: not supported by the sPAPR machine if not
set in CAS.
I have a feeling that the CPU hot unplug issue might be related
with the lack of CAS negotiation step as well, but only way to be
sure is to further understanding how the CAS negotation interfere
with the device hot unplug. If needed we'll have to implement the
client architecture support hypercall as well in the future.
Until then, I believe these hypercalls have a value of their own and
are worth being pushed upstream.
Unfortunately, these changes break the Travis build on MacOS.
Hmpf .... how can I run this Travis build to see the errors? I've
here and found out something about making a Github pull request and
then https://travis-ci.org/qemu/qemu runs the Travis build in the
Is this a valid way of running it?
Just managed to run the build and saw the error. I'll fix it in v2.
