keyboard.c, keymap.c: Use bool for booleans.

* dispnew.c (sit_for): Distinguish between 3-way display_option
and boolean do_display.

* menu.c (single_menu_item):
* nsmenu.m (ns_update_menubar):
* process.c (wait_reading_process_output):
* search.c (scan_buffer, scan_newline):
Use bool for boolean.
* keyboard.c (timers_run, swallow_events)
(detect_input_pending_run_timers):
* process.c (wait_reading_process_output):
Use unsigned for counter where wraparound-on-overflow is desired,
since unsigned is guaranteed to have that behavior and signed is not.
(read_char): Use ptrdiff_t for string length.
(get_input_pending): Remove first argument, since it was always
the same pointer-to-int (now pointer-to-boolean) &input_pending,
and behave as if it had that value.  Return new value of
input_pending.  All callers changed.
* keyboard.h (struct kboard): Use unsigned : 1 for boolean member
immediate_echo.  Use ptrdiff_t for echo_after_prompt, since it's
a string length.
* keymap.c (push_key_description): Omit last arg, which was always 1.
All callers changed.
