API: gdk: Add gdk_window_new_child() and gdk_window_new_input()

Browse Source 
This is an attempt to get rid of gdk_window_new() for more specific use
cases. These 2 are for client-side windows - regular ones and input-only
ones resepectively.

So far all those functions just call into gdk_window_new().
