Clean up Haiku code
* src/haiku_support.cc (movement_locker, class EmacsWindow)
(MouseMoved): Delete `movement_locker' and associated hack,
since it's superseeded by some code in haiku_read_socket.
(key_map, key_chars, dpy_color_space, popup_track_message)
(alert_popup_value, grab_view, grab_view_locker)
(drag_and_drop_in_progress): Write comments and fix
initializers.
* src/haikuterm.c (haiku_read_socket): Update comment.
