`BARCODE_CONTENT_SEGS`, `z_rt_XXX()` -> `z_ct_XXX()`;
move `encoded_data`/`row_height` to end of `zint_symbol`
(see ZXing-C++ issue #883)
manual: update re `content_segs`; `my_symbol` -> `symbol`;
improve MicroPDF417 description
those in "backend/common.h", which are prefixed by `z_` - makes
symbol clashes more unlikely when zint is statically linked
(ticket #337, props Ulrich Becker)
DOTCODE: fix padding allowance (10 -> 52 - probable max 35) to
cover cases with large no. of columns requested and little data,
to prevent `codeword_array` buffer overflow
AZTEC/CODEONE: some code fiddling
general_field: prefix defines with `GF_`, shorten static funcs
prefix `general_field_` -> `gf_`
fields `raw_segs` and `raw_seg_count` instead of `text`, and to
do so for all symbologies, using new common funcs `rt_cpy()` etc.
MICROPDF417: return ECC percentage in top byte of `option_1`
DBAR_EXP_STK: return `option_2`/`option_3` feedback
CLI: change warning text "ignoring" -> "**IGNORED**"
GUI: show feedback for DBAR_EXP_STK, MICROPDF417, UPNQR
ctest: fix recent inability to run tests via "ctest" on Windows
(MSVC) by using cmake 3.22 feature `ENVIRONMENT_MODIFICATION`
manual: document feedback and RAW_TEXT in new "Feedback" section;
rephrase some symbology descriptions
test suite: new general-use arg "-a"; add `func_name` to context;
new "test_bwipp" test for testing BWIPP against ZXing-C++
`ZINT_WARN_HRT_RAW_TEXT` if set when outputting HRT (ZXing-C++
issue 883, props Axel Waggershauser)
README: Pharmacode -> One-Track, Pharmacode 2-trace -> Two-Track
`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
