Add functions to set frame size and position in one compound step

* lisp/frame.el (set-frame-size-and-position): New function.
* src/frame.c (adjust_frame_size): Handle requests to set size
and position.
(Fset_frame_size_and_position_pixelwise): New function.
* src/gtkutil.c (xg_frame_set_size_and_position): New function.
(xg_wm_set_size_hint): Handle any non-NorthWestGravity values
for child frames only.  Some GTK implementations don't like
them.
* src/gtkutil.h (xg_frame_set_size_and_position.): Add external
declaration.
* src/termhooks.h (set_window_size_and_position_hook): New hook.
* src/w32term.c (w32_set_window_size_and_position): New
function.
(w32_create_terminal): Make it the Microsoft Windows API
set_window_size_and_position_hook.
* src/xterm.c (x_set_window_size_and_position_1)
(x_set_window_size_and_position): New functions.
(x_create_terminal): Make x_set_window_size_and_position the
set_window_size_and_position_hook for the X protocol.
* src/xterm.h (x_set_window_size_and_position): Add external
declaration.
* etc/NEWS: Announce new functions.
