(xg_resize_outer_widget): Only do one of set_geometry or
set_char_size.
(xg_frame_resized): Renamed from xg_resize_widgets. Remove all
operations on widgets here. Just set frame size if needed.
(flush_and_sync, x_wm_size_hint_off, xg_pack_tool_bar): New functions.
(xg_frame_set_char_size): Call x_wm_size_hint_off before resizing.
(x_wm_set_size_hint): Set size hints on the edit widget only, not
the whole frame.
(xg_create_tool_bar): Move attachement of the tool bar to
xg_pack_tool_bar. Do not attach the tool bar if there are no items.
(free_frame_tool_bar): Remove call to SET_FRAME_GARBAGED.
