raster/vector: EAN/UPC: fix calculation of image/vector height to

Browse Source 
allow for heights smaller than `textoffset` when have add-on
  (buffer overflow for raster, outside vector height for vector)
raster: EAN/UPC: make sure don't overwrite add-on stuff when
  line-copying guard descenders by limiting copy width
ZBarcode_Encode_Segs: allow for multiple (stacked) rows when
  setting absolute minimum height;
  state stacked symbols max in error message
DBAR_EXP: check length on encoding method 6 before trying to parse
  3-digit currency string with `z_to_int()`
CLI: stop looping over data args when have error;
  suppress taint warning by using fixed `malloc()` size for
  `arg_opts` instead of `argc`
general: use `vsnprintf()` instead of `vsprintf()` if not C89
ULTRACODE: don't call `ult_generate_codewords()` if `length` 0
  from fragment processing (avoids `assert()`)
clang-tidy -> 23 & suppress some warnings
test suite: fuzz: leave Z_FUZZ_DEBUG to compiler, fix comment
general: some minor code-formatting on touched files
README.deb -> README.debian (avoid confusion with actual ".deb")
BWIPP: update to latest
