- move basic definitions from util.h to cutils.h
- use CONFIG_SESSION for session support (undefined if CONFIG_TINY)
- define CompleteFunc and CT_xxx flags for completion functions
- pass CompleteFunc to xxx_complete() functions
this allows more generic implemetation, without including qe.h
- rename fill_border() as fill_window_slack() for readability
- add QELEVEL environment variable to detect recursive invocation
- use stricter parser for load_ligatures()
- bump VERSION to 5.3.4u

- add CompletionDef flags:
- CF_FILENAME to use `/` as separator

- rename and extend CompletionEntry as CompletionDef
- create xxx_completion CompletionDef structures
- rename xxx_completion() functions to xxx_complete()
- register CompletionDef structs with qe_register_completion()
- add (start, end) range in CompleteState
- use eb_puts() and eb_putc() instead of eb_printf()
- simplify eb_delete_chars()
- ignore left pane in compare-windows()
- simplify qe_list_bindings()
- improve command and variable completion popup
- add qe_save_variables(s, b)
- add use_session_file global variable
- add VarDef::modified flag to detect customized variables
- set modified flag upon variable modifications
- dired: set modified flag when changing in dired variables
- fix BUG in qe_register_variables, did not set set_value handler
on last VarDef element
- make qe_save_variables() public
- remove do_save_variables(), move save_session() to parser.c
- add eb_puts() and eb_putc() for consistency
- add WF_HIDDEN window flag to temporarily flag windows to be deleted
- add do_hide_window(), do_delete_all_windows() and do_delete_hidden_windows()

- add do_create_window(s, filename, layout) to restore window layout
- add qe_save_macros() to save keyboard macros to session file
- detect keyboard macro redefinitions and avoid duplicates
- add qe_save_open_files() to save list of open files and directories
- pass `all` flag to do_delete_other_windows() to force complete deletion
- add qe_load_session() and do_save_session():
* qe_load_session() is invoked before parsing the command line if
use_session_file is set, via the config file or command line option (-s)
* do_save_session() is invoked just before closing qemacs. It can also
be invoked as a command and shows a popup window with the contents of
the session file produced instead of saving it.
- fix CRASH BUG in command definitions, missing argument specifier caused
spurious crashes when invoking commands from script files. This affected:
find-file(), find-file-other-window(), find-alternate-file(), kill-buffer()
load-file-from-path().
- insert newly created windows in list in top-down left-right order
- update WF_RSEPARATOR flag upon deletion of vertically split window
