- new backend rendering via egl via gbm directly on a drm device
- refine EGLContext and EGLSurface dependencies through lifetimes
- fixup the old winit backend to work with these changes
- add new example using the drm backend instead
- change GliumDrawer to be static for the drm example
- Make id be an `u64` to be able to populate it by a hash
- Add internal interface to get a mutable capabilities reference from a `Seat`.
- `InputConfig` type does not need to be `Sized` on `InputBackend`
