ilo: clean up draw and rectlist state emission

Browse source 
Add these new high-level functions

  ilo_render_get_draw_dynamic_states_len()
  ilo_render_emit_draw_dynamic_states()
  ilo_render_get_rectlist_dynamic_states_len()
  ilo_render_emit_rectlist_dynamic_states()
  ilo_render_get_draw_surface_states_len()
  ilo_render_emit_draw_surface_states()

for draw and rectlist state emission.  They are implemented in the new
ilo_render_dynamic.c and ilo_render_surface.c.
