Hi guys,
I put the RFC mark because I don't know if this is the best way to
enhance the support for LXC 3.0. Considering this patch, I can use
both o version without any issue, but I would like to see other points
of view. I'm not completely right about this approach.

This patch introduce the new settings for LXC 3.0 and higher. The older
versions keep the compatibility to deprecated settings for LXC, but
after release 3.0, the compatibility was removed. This commit adds the
support to the refactored settings.

Since this is something between PV and HVM, it makes sense to put the
setting in place where domain type is specified.
To enable it, use It is
also included in capabilities.xml, for every supported HVM guest type - it
doesn't seems to be any other requirement (besides new enough Xen).

builder="hvm" is deprecated since Xen 4.10, new syntax is type="hvm" (or
type="pv", which is default). Since the old one is still supported,
still use it when writing native config, so the config will work on
older Xen too (and will also not complicate tests).

This is a respin of my old PVHv1 patch[1], converted to PVHv2.
Should the code use "PVH" name (as libxl does internally), or "PVHv2" as in
many places in Xen documentation? I've chosen the former, but want to confirm
it.
Also, not sure about VIR_DOMAIN_OSTYPE_XENPVH (as discussed on PVHv1 patch)
