Update Android port

* doc/lispref/frames.texi (On-Screen Keyboards): Describe return
value of `frame-toggle-on-screen-keyboard'.
* java/org/gnu/emacs/EmacsSurfaceView.java (surfaceChanged)
(surfaceCreated, EmacsSurfaceView): Remove unuseful
synchronization code.  The framework doesn't seem to look at
this at all.

* java/org/gnu/emacs/EmacsView.java (EmacsView):
(onLayout): Lay out the window after children.
(swapBuffers): Properly implement `force'.
(windowUpdated): Delete function.

* lisp/frame.el (frame-toggle-on-screen-keyboard): Return
whether or not the on screen keyboard might've been displayed.

* lisp/minibuffer.el (minibuffer-on-screen-keyboard-timer):
(minibuffer-on-screen-keyboard-displayed):
(minibuffer-setup-on-screen-keyboard):
(minibuffer-exit-on-screen-keyboard): Improve OSK dismissal when
there are consecutive minibuffers.

* lisp/touch-screen.el (touch-screen-window-selection-changed):
New function.
(touch-screen-handle-point-up): Register it as a window
selection changed function.

* src/android.c (struct android_emacs_window)
(android_init_emacs_window): Remove references to
`windowUpdated'.
(android_window_updated): Delete function.
* src/android.h (struct android_output): Remove
`last_configure_serial'.
* src/androidterm.c (handle_one_android_event)
(android_frame_up_to_date):
* src/androidterm.h (struct android_output): Remove frame
synchronization, as that does not work on Android.
