Jack Ding 9e884de68a Add HPET timer support for x86 guests
This commit adds support for the High Precision Event Timer (HPET) for
x86 guests in the libvirt driver. The timer can be set by image property
'hw_time_hpet'. By default it remains turned off. When it is turned on
the HPET timer is activated in libvirt.

If the image property 'hw_time_hpet' is incorrectly set to a
non-boolean, the HPET timer remains turned off.

Added support for the High Precision Event Timer (HPET) for x86 guests
in the libvirt driver when image property ``hypervisor_type=qemu`` is set.
The timer can be set by setting a ``hw_time_hpet=True`` image property
key/value pair. By default HPET remains turned off. When it is turned on
the HPET is activated in libvirt.
