    Avoid signed integer overflow when converting Time to ptrdiff_t. · 203a9eb0

    New macros.
    (position_to_Time, Time_to_position): New functions.
    (gen_help_event, kbd_buffer_get_event): Use them.
    * systime.h (Time) [emacs && !HAVE_X_WINDOWS]:
    Go back to plain 'unsigned long', so that 'Time' is the same
    for both X and non-X builds; this is less likely to cause surprise.
    * termhooks.h: Remove compile-time check that Time and ptrdiff_t
    are the same size; this is no longer required.
