Libvirt provides a portable, long term stable C API for managing the
virtualization technologies provided by many operating systems. It
includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware
vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER
Hypervisor.

Parse libxl_hwcap accounting for versions since Xen 4.4 - Xen 4.7. libxl_hwcaps is a set of cpuid leaves output that is described in [0] or [1] in Xen 4.7. This is a collection of CPUID leaves that we version in libvirt whenever feature words are reordered or added. Thus we keep the common ones in one struct and others for each version. Since libxl_hwcaps doesn't appear to have a stable format across all supported versions thus we need to keep track of changes as a compromise until it's exported in xen libxl API. We don't fail in initializing the driver in case parsing of hwcaps failed for that reason. In addition, change the notation on PAE feature such that is easier to read which bit it corresponds.

LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
