gui_session: split alloc_view_handle, view_handle

Browse Source 
Express the allocation of a new view handle by a dedicated RPC function
instead of passing an invalid view handle to the existing 'view_handle'
function.

This eliminates the notion of invalid view handles at the GUI session
interface, clearing the way for managing view handles via an Id_space.
