fb: introduce fb_rebuild()
When an fb has been resized, all the pages can be forced to go through a backend free->alloc cycle by calling this function. This process gets queued and realized as the pages pass through the inactive state. This does mean that whatever pages are already queued as ready still get displayed, so it's not exactly without racing/flickering at the fringes on window growth. It's possible to do something with the pages in the ready queue to combat this, but for now I'm just leaving them be to keep it simple. The ready pages could be stretched or something...
