Pull out dependencies on SGIMAGE using #ifdef FAISALMEMON_S4_SGIMAGE This is a temporary measure until we see the big picture and work out the best way to model it.
Add proper def file for guest video driver now that it compiles. Put ifdef hack FAISALMEMON_S4_SGIMAGE around the reqhandlerextensionlib.mmp because this appears to be consuming a platform available sgresource header only available in s4. We want a minimal port for s3 here.
