Charlie Gordon bd50376780 Various improvements
- add charset.h
- add tools/unitable.c to compute unicode_width.h
- add tools/unicode_gen.c to compute more unicode tables
- use Unicode 15.0.0
- add rules to compute width tables from Unicode tables and TTY
- 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
