Fix incorrect NextStep tool-bar-mode -- wrong number of rows in frame.

* nsterm.h (struct ns_output): New flag, in_animation.
* nsfns.m (Fx_create_frame): Initialize in_animation flag.
* nsmenu.m (free_frame_tool_bar, update_frame_tool_bar): Set
in_animation flag around call to "setVisible". Set new tool bar
height before call to setVisible.
* nsterm.m (x_set_window_size): Don't call [view setRow:
andColumns:] as this fools the subsequent call to updateFrameSize
from performing the real resize.
(windowDidResize): Don't update anything when in_animation is
non-zero.

Trace output.

* nsmenu.m (free_frame_tool_bar, update_frame_tool_bar)
(EmacsToolbar):
* nsterm.m (x_set_window_size, updateFrameSize)
([EmacsView setRows: andColumns:])
