RFC vmwgfx_fb.c: enable double buffering

Hi Thomas, Dave,

Further to my first patch [1] for the vmware framebuffer driver, I
have created a patch that enables double buffering [2]. There is also
some code that demonstrates proper working functionality as well [3]
and a video that demonstrates proof of concept [4]. I'm actually
headed to FOSDEM to talk about that last one today :-)

I know that the VMWare virtual SVGA device is a bit tricky, so it
would mean quite a bit to me if you could take a look at it.

Thanks,

C
