debian: updated using https://salsa.debian.org/debian/zint as
template, props Dmitry Smirnov (ticket #147, props John Crisp); TODO: enable building with the GS1 Syntax Engine; this involved auditing copyrights which prompted the next item re "tif.c" and will prompt the next next item "pdf417.c" tif.c: replaced LZW compression with tree-based one due to "tif_lzw.h"'s original BSD-TAHOE license which has the equivalent of the "advertising clause", new implementation (which is much faster anyway) props Harald Kuhr and Bob Montgomery pdf417.c: TODO: Replace all code adapted from "pdf417.frm" as it was released under GPL v2.0 or later pdf417.h: replace unnecessary "pdf417.frm" references with ISO/IEC standard as 1st step re above, some expanded comments general: Codablock-F -> Codablock F (i.e. lose hyphen) cmake: frontend/frontend_qt: go back to only setting RPATH on macOS as not Debian compatible and it seems it's not a good idea on Linux anyway; TODO: check BSD + other Unixes CLI/GUI: make "--verbose" option official and document tools/gen_eci_sb_h.php/gen_eci_mb_h.php: add SPDX Unicode-3.0; update haible.de/bruno tarball info - "GB18030.TXT" no longer in "jdk-1.4.2/" so mention "libiconv-1.11/" version instead (same) general: add various SPDXs and normalize some Copyrights reedsol.c: malloced `logt`/`alog` tables int -> short (slight performance improvement) aztec.c: add copyrights, some code fiddling BWIPP: update to latest
