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.
