Add HPET emulation to qemu (Beth Kon)
This patch adds HPET emulation. It can be disabled with -disable-hpet. An hpet
provides a more finely granular clocksource than otherwise available on PC.
This means that latency-dependent applications (e.g. multimedia) will generally
be smoother when using the HPET.
