as to fully comply with BSD license (for why Library GPL 2+ not compatible see https://opensource.stackexchange.com/a/6701), ~3% slower (maybe), +~6K extra in data (gb18030.c, gb2313.c & sjis.c removed, mapping .TXT files moved to backend/tools/data & extra ones added, 2 new PHP generators) GUI: CODE39/EXCODE39: show/hide HIBC check digit option in addition to enable/disable (less confusing) CLI: batch: pedantic check for EOF using intChar in newline fgetc() loop test_args.c: don't use WIFEXITED(), WEXITSTATUS() on Windows manual: lessen some copy/paste verbiage by referring back, other small tweaks/typos
