`BARCODE_PLAIN_HRT` option for `output_options` - for use
primarily by ZXing-C++ but may be generally useful;
centralize setting of HRT using new common `hrt_cpy_nochk()` etc.
routines to ensure `text_length` always set
PLESSEY: add show default check characters option
CODE32: ignore `option_2` (check digit options)
PZN: ignore `option_2` (check digit options) except when indicates
PZN7 only
DPD: exclude DEL from ident tag also
out_maybe_mkdir: fix `utf8_to_wide()` return (Windows only)
general: replace use of `strcpy()` etc. (except for test suite)
with `memcpy()`, `hrt_()` etc. in lib & `cpy_str()` etc. in CLI
& `cpy_bytearray_left()` in backend_qt
clang-tidy: update README reflecting above
backend_tcl: use sizeof(primary) to check length; tabs -> spaces
general: various code fiddling
docs: pandoc 3.6.2 -> 3.6.3
to suppress warnings about `errtxtf` operand number "%<n>$" args;
enable some further warnings
test suite: enable -Wpedantic and fix/suppress any warnings
processing on last segment
DXFILMEDGE: error message XXX-XX -> NNN-NN, fix comments
README.bsd: update to latest Free/Open/Net, "Run" section
test suite: CODABLOCKF: extra tests from Okapi
test suite: support DATAMATRIX ^PROG, ZXing++ AZRUNE
manual/man page: CODEONE: fix WxH -> HxW and Version C width
manual: backtick literals
change # 147 -> 127 to use up barcode # holes;
use "common.h" funcs `str_to_uppercase()` -> `to_upper()`,
`count_char_occurrences()` -> `chr_cnt()`;
prefix defines with `DX_` and funcs with `dx_`;
`ZINT_DEBUG_PRINT` -> `symbol->debug & ZINT_DEBUG_PRINT`;
bools to ints; use `posn()` to check for slash (returns length);
restrict line lengths to 118; suppress some clang-tidy warnings;
normalize some error messages;
check for single "A" if any (`sscanf()`);
use compliant height default; some whitespace formatting;
Tcl: add DXFILMEDGE support
docs: document DXFILMEDGE; update to latest pandoc
test suite: ZXingCPP: DXFILMEDGE support
