A long time ago, `read_key_sequence` used to read the keymaps at the
start, so if something happened between this start and the moment
the user actually hits a key, `read_key_sequence` could end up using
the wrong keymaps.  To work around this problem, the code used
`record_asynch_buffer_change` to try and trigger `read_key_sequence`
to re-read the keymaps in some known cases.

Several years ago, `read_key_sequence` was changed so as to read the keymaps
only once the user hits a key, making this machinery now redundant
(and also harmful apparently in bug#5803 because it introduces
"spurious" events).

So we here remove `record_asynch_buffer_change` and the
`BUFFER_SWITCH_EVENT` and `Qbuffer_switch` pseudo-events it generated.

* src/termhooks.h (enum event_kind): Delete `BUFFER_SWITCH_EVENT`.
* src/keyboard.c: (record_asynch_buffer_change): Delete function.
(syms_of_keyboard): Delete `Qbuffer_switch`.
(force_auto_save_soon, readable_events)
(kbd_buffer_store_buffered_event, kbd_buffer_get_event)
(make_lispy_event):
* src/xterm.c (handle_one_xevent):
* src/w32term.c (w32_read_socket):
* src/process.c (wait_reading_process_output)
(read_and_dispose_of_process_output, exec_sentinel): Simplify accordingly.

Run "TZ=UTC0 admin/update-copyright $(git ls-files)".

* src/menu.c (menu_items_inuse): Now bool, instead of a
Lisp_Object that is always Qt or Qnil.  All uses changed.
