Refactor window-system configuration

This change streamlines the window system selection code in
configure.in and moves many common function declarations from
window-specific headers to frame.h.  It introduces a new TERM_HEADER
macro in config.h: we set this macro to the right header to use for
the window system for which we're compiling Emacs and have source
files include it indirectly.  This way, we don't have to teach every
file about every window system.

+        to match header.
+
+        * w32term.h (FRAME_X_WINDOW): Use FRAME_W32_WINDOW instead of
+        directly accessing frame internals.

+        Windows.

+        * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
+        window system declarations.

+        x_set_window_size, x_sync, x_get_focus_frame,
+        x_set_mouse_position, x_set_mouse_pixel_position,
+        x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

+
+        * Makefile.in: Define WINDOW_SYSTEM_OBJ to hold objects needed for
