Message:

Additions/linux/vboxvideo: Pass a new framebuffer to vbox_crtc_do_set_base
bugref:8282: Additions/linux: track kernel changes to vboxvideo in our own tree

This modifies vbox_crtc_do_set_base() to take a new framebuffer to
be activated, instead of the existing framebuffer attached to the crtc.
This change allows the function to be given the new framebuffer from
a page-flip request.
