protocol: introduce wl_shell_surface

Browse source 
Requests like 'move' and 'set_toplevel' are really methods of a surface,
not methods of a global shell object. Move all these methods to a new
interface, wl_shell_surface.

The global object wl_shell will contain only 'get_shell_surface'
request, which creates and associates a wl_shell_surface object to a
given wl_surface object.

This will also give the shell plugin (if you look at the demo
compositor) means to store per-surface private data in a natural way.

Due to a limitation in delete_id event handling on client side, the
client must destroy its wl_shell_surface object before destroying the
wl_surface object. Otherwise it may just leak an id.
