til_fb: switch til_fb_ops_t.init() to use til_setup_t

Until now the fb init has been receiving a til_settings_t to
access its setup.  Now that there's a til_setup_t for
representing the fully baked setup, let's bring the fb stuff
up to speed so their init() behaves more like
til_module_t.create_context() WRT settings/setup.

This involves some reworking of how settings are handled in
{drm,sdl}_fb.c but nothing majorly different.

The only real funcitonal change that happened in the course of
this work is I made it possible now to actually instruct SDL to
do a more legacy SDL_WINDOW_FULLSCREEN vs.
SDL_WINDOW_FULLSCREEN_DESKTOP where SDL will attempt to switch
the video mode.

This is triggered by specifying both a size=WxH and fullscreen=on
for video=sdl.  Be careful though, I've observed some broken
display states when specifying goofy sizes, which look like Xorg
bugs.
