* dispnew.c: Fix problems uncovered by gcc -Wstrict-prototypes.

(copy_glyph_row_contents): Remove; not used.
(frame_row_to_window, check_current_matrix_flags):
(window_change_signal): Now static, since they're not used elsewhere.
(check_current_matrix_flags): Surround with "#if 0", since its
only use is in a comment.  Maybe both the comment and the "#if 0"
stuff should be removed?
