Fix minor problems found by static checking.

* keyboard.c (poll_for_input_1, input_polling_used):
Define only if HAVE_NTGUI.
* xmenu.c (popup_activate_callback): Omit unnecessary
check against USE_X_TOOLKIT, which must be defined here anyway.
* xterm.c, xterm.h (x_dispatch_event) [! (USE_X_TOOLKIT || USE_MOTIF)]:
Now static.
