Introduce ipmi device emulations for the power management of the hypervisor

I. IPMI (intelligent platform maintenance interface)

II. Use the qemu & virsh command line as the "startcmd" parameter for IPMI emulations
1. for qemu command line
- Supported qemu version: at least from qemu v2.2
- How to define:
   #1 Create a BMC, normally done from ipmi_sim
   #1.1 for internal: basic BMC inside qemu, like watchdog timer.
   -device ipmi-bmc-sim,id=bmc0
   #or 1.2 for external: connects to an external BMC over a chardev, like power
   #management, watchdog timer, set sensor value.
   #(need to install OpenIPMI in the hypervisor)
   -chardev socket,id=ipmi0,host=localhost,port=9002,reconnect=10 \
   -device ipmi-bmc-extern,id=bmc1,chardev=ipmi0 \
   #2 Attach the BMC to an interface
   -device isa-ipmi-kcs,bmc=bmc1 \
