(#5) add sdl frame buffer support.
Now libvirt still supports sdl frame buffer, and it may take three
parameters: display,xauth,fullscreen. This patch enable the libvirt-cim
to accept these configuration and pass them in XML define to let
libvirt know about it. Exposed interface could be found in the file
ResourceAllocationSettingData.mof.
This Patch also fix some memory leak problem.
#5 fixed the memory leak problem in Virt_VirtualSystemManagementService.c.
