uterm: video: return -EOPNOTSUPP when opengl is not supported
When the backend does not implement display_use() then we return an error

This adds a fully working fbdev backend to the uterm library. This allows

The fbdev backend is not yet hooked up into kmscon. There are still some
remaining issues as we do not have OpenGL on fbdev if EGL is not compiled
with fbdev backend (which is usually not).

console: rewrite console layer
This is a rewrite of the whole console layer so we can remove the
kmscon_buffer object to speed up the console.
This removes the split between the scroll region and the two margins so we
can resize margins in O(1). This also correctly merges the remaining
console modes so vte does not have to track them.
Btw. vim runs smoothly on kmscon with this console layer now (finally!).

We currently do not optimize this for performance. In fact, this reduces
