    focus-in-hook and focus-out-hook don't accurately reflect actual
    user-visible focus states.  Add a new focus interface and mark the old
    one obsolete.
    
    * doc/lispref/frames.texi (Input Focus): Document new focus
    functions.  Remove references to the now-obsolete focus hooks.
    
    * lisp/frame.el (frame-focus-state): New function.
    (after-focus-change-function): New variable.
    (focus-in-hook, focus-out-hook): Move to lisp from C;
    mark obsolete.
    
    * lisp/term/xterm.el (xterm-translate-focus-in)
    (xterm-translate-focus-out): Track tty focus in `tty-focus-state'
    terminal parameter; call `after-focus-change-function'.
    (xterm--suspend-tty-function): New function.
    
    * src/frame.c (Fhandle_switch_frame): Update docstring; don't call
    focus hooks.
    (focus-in-hook, focus-out-hook): Remove: moved to lisp.
    (syms_of_frame): Remove unread_switch_frame; add
    Vunread_switch_frame.
    
    * src/keyboard.c:
    (Finternal_handle_focus_in): New function.
    (make_lispy_event): Always report focus events to lisp; don't
    translate them to switch events sometimes.  Lisp can take care of
    creating synthetic switch-frame events via
    `internal-handle-focus-in'.
    
    * src/w32term.c (x_focus_changed): Remove switch-avoidance logic:
    just directly report focus changes to lisp.
    
    * src/xterm.c (x_focus_changed): Remove switch-avoidance logic:
    just directly report focus changes to lisp.
