* pass `QEmacsState` to key grab functions
* clear `grab_key_opaque` when freeing windows, buffers, mode_data
* add checks on window and buffer pointers in key grab functions
* this should fix a crash bug when deleting unsynched buffers from bufed
* fix `reload_buffer` to update buffer `file_size` and `mtime` fields
* check buffer file before invoking commands that modify the buffer
* check buffer file after command that changes the current window
or the current window's buffer
* rename and pass flags to byte quoting functions:
`byte_quote` -> `strquote_byte`
* add `eb_print_style` to output data to a buffer in a given style
* add `eb_print_field` to output a field name and value using styles
* use styles in describe commands
* improve byte stats and page layout output in `describe-buffer`
* add `wall-chart` command (sorted list of bindings)
* add `describe-help` command
* add `#` at the beginning of the comand argument description
to disable command when current window is a popup or the minibuf
* update command definitions
* add `eb_put_filename()` to encode buffer or file names with
non-ASCII characters according to PF_xxx flags
* add `CF_SAVE_LIST` flag for completions to store the list
of matches in `MinibufState`
* fix bufed and dired layout issues
* fix buffer and filename completion popup layout
* add commands to control display of Unicode and non printing
charcaters in buffer or file names:
- U toggles unicode display
- \ cycles through 4 possible encodings: ? ^J \x10 \010
* use `(*fp)()` syntax for indirect function calls
* use `BC_REUSE | BC_CLEAR` to avoid killing the `*occur*` buffer
* this ensures the `*occur*` buffer stays current in windows that show it
* modify the `BC_CLEAR` semantics to imply `BC_REUSE`
* simplify calls: remove redundant `BC_REUSE` flag
The `occur` command creates an `*occur*` buffer to show the matches in the current buffer.
If we used `occur` to search another string, then the old *occur* buffer was still there and our new search result were not shown. Killing buffer `*occur*` before creating a new one solves the problem.
* Fix `put_status`/`put_error` behavior
- use `put_error` instead of `put_status` for command errors

optional argument, value is incremented if argument is not provided.
- add `swap_int()`
- add commands for multi-line cursor:
* `start-multi-cursor` on `C-x <`
set the mark for a region with a cursor on each line
* `end-multi-cursor` on `C-x >`
end recording the multi-line cursor region and start editing
cancel the multi-line cursor with `C-g`
* `add-multi-cursor` on `C-x #`
add an extra cursor at point. Activate multi-line cursor editing
with `C-x \`
