2022-08-07	til: experimentally fragment-centric page api	Vito Caputo
	It seems like it might be most ergonomic and convenient for everything to just use til_fb_fragment_t and rely on ops.submit to determine if the fragment is a page or not, and if it is how to submit it. This commit brings things into that state of the world, it feels kind of gross at the til_fb_page_*() API. See the large comment in til_fb.c added by this commit for more information. I'm probably going to just run with this for now, it can always get cleaned up later. What's important is to get the general snapshotting concept and functionality in place so modules can make use of it. There will always be things to cleanup in this messy tangle of a program.

	The immediate impetus for adding this is to enable running rototiller even on headless machines just for the sake of getting some FPS measurements. It'd be nice to get a sense for what FPS rototiller would experience on larger modern machines like big EPYC or Threadripper systems. But it seems most of those I can get access to via others running them on work hardware or the like can at most just run it over ssh without any display or risk of disrupting the physical console. But this is probably also useful for testing/debugging purposes, especially since it doesn't bother to synchronize flips on anything not even a timer. So a bunch of display complexity is removed running with video=mem as well as letting the framerate run unbounded. Having said that, it might be nice to add an fps=N setting where mem_fb uses a plain timer for scheduling the flips. Currently the only setting is size=WxH identical to the sdl_fb size= setting, defaulting to 640x480.
