Qemu-1.0 rc

Qemu-1.0 release了, 但是目前還是在RC stage，http://wiki.qemu.org/Download
從source code可以看出，以前比較屬於H/W engeineer的coding style有一些改變囉~~越來越有 fu 了~~新的version也有支援一些ARM A15的指令，和 ARM 相關的 change log 如下:

1. QEMU now supports the new Cortex-A15 instructions in linux-user mode (via "-cpu any"): VFPv4 fused multiply-accumulate (VFMA, VFMS, VFNMA, VFNMS) and also integer division (UDIV, SDIV).
2. The vexpress-a9, versatileab, versatilepb and realview-* boards now have audio support.
3. QEMU is known not to work on ARM hosts in this release. (ARM target emulation is fine.)

一些額外自已可以設定的參數，也使用了script 去parsing qemu-options.hx以產生qemu-options.def讓c file去include，增加了一些小彈性。
