x11: use new option stuff to implement fullscreen

- remove VOCTRL_FULLSCREEN and VOCTRL_GET_FULLSCREEN
- have your own m_config_cache for the fullscreen option
  (vo->opts_cache cannot be used because you lose per-option change
  notifications, and it'd be a mess anyway)
- use VOCTRL_VO_OPTS_CHANGED to update it
  (it's used for convenience)
- when updating it, check for the fullscreen option
  (wasn't sure how to do it best; currently, it compares the raw
  option pointers, but this could be changed)
- do not send VO_EVENT_FULLSCREEN_STATE on FS change
- instead write the option on FS change
  (assign in opt. struct + m_config_cache_write_opt)
