- make kill buffers system buffers (not displayed in buffer-list)
- only create *scratch* buffer in qe_kill_buffer() if needed
- prevent crash if killing style, log or kill buffers
- display \n as ^J in minibuf
- separate buffer and window specific mode data management, new API:
QEModeData *qe_create_buffer_mode_data(EditBuffer *b, ModeDef *m);
void *qe_get_buffer_mode_data(EditBuffer *b, ModeDef *m, EditState *e);
QEModeData *qe_create_window_mode_data(EditState *s, ModeDef *m);
void *qe_get_window_mode_data(EditState *e, ModeDef *m, int status);
int qe_free_mode_data(QEModeData *md);
- make a list of buffer specific mode data areas so multiple major modes
can co-exist in different windows for the same buffer
- add mode.mode_free callback to release buffer specific resources
- remove buffer.close callback
- shell state is now buffer specific shell_mode data
- clean up compress and archive mode
- show more buffer modes in buffer-list

This will ease the change of int type to support huge files in 64 bits.
- use the page cache also for offsets beyond the page cache.
- simplify eb_insert_low_level() and eb_insert_buffer() to avoid
pathological cases of kill/yank sequences loading to catastrophic
fragmentation. eg: kill a 1 byte region and yank it 1000 times

take window before which to move arg window, use NULL to append at the end.
If qs->active_window is NULL, set it to the first window
- add buffer flags BF_IS_LOG and BF_IS_STYLE
- create style buffers with a meaningful name
- create log buffers with a meaningful name
- add window flag WF_POPLEFT for dired interactive buffers
- no longer create process buffer and find files in dired pop left pane

- prevent do_find_file_other_window() from splitting window if too shallow
- fix window fusion algorithm when deleting left pane with split right pane
- prevent delete-other-windows() from minibuf and poups
- use mode structure as signature for bufed-mode, shell-mode
- make list-buffers open an interactive popup window
- toggle full buffer list with '.'

- added utf8_is_trailing_byte(b) to standardize testing for this
- improve hex searching by 50% using eb_read_one_byte()
- improve regular searching by 35% by removing extra calls to eb_nextc()
- simplify eb_read() and eb_write() primitives
- make eb_write() return number of bytes actually written
- add eb_read_byte(buffer, offset) to read a single byte
- simplify eb_nextc() accordingly
- clean search and replace code
- fix point position upon matches in forward and backward directions
- prevent reverse search from find overlapping matches
- hilite current match
- add style search-match to hilite the current match in incremental-search
defaults to cyan / magenta
- C-l centers the window
- C-q quotes next character in incremental search
- C-w grabs the word at point
- C-y grabs from point to next end of line
- A-b cycles unihex hex and normal search
- A-w toggles word matching
- A-y yanks last kill in search string
- add same control keys to query-replace command
- fix searching and replacing in hex and unihex modes
- wrap search after failure
- pass search data as u32 buffer

alternate behaviours in internal commands
- fix do_center_cursor() when point is before window start
- add do_center_cursor_maybe() to center window if point is not visible
- allow C-q to quote DEL key (ASCII 127)
