Fix int/EMACS_INT use in textprop.c and window.c.

 window.c (Fpos_visible_in_window_p, Fdelete_other_windows)
 (Fselect_window, window_scroll_pixel_based)
 (window_scroll_line_based, Frecenter, Fset_window_configuration):
 Use EMACS_INT for buffer positions.
 textprop.c (validate_interval_range, interval_of)
 (property_change_between_p, Fadd_text_properties)
 (set_text_properties_1, Fremove_text_properties)
 (Fremove_list_of_text_properties, Ftext_property_any)
 (Ftext_property_not_all, copy_text_properties)
 (text_property_list, extend_property_ranges)
 (verify_interval_modification): Use EMACS_INT for buffer
 positions.
