a14fe77aa0 EANX_CC/UPCA_CC: fix crash in dbar_date() on not checking length
in `cc_binary_string()`, ticket #300 (#5 & #6), props Andre Maute;
  add other checks for length on processing encoding mode
PDF417: fix out-of-bounds crash on overrunning string and codeword
  buffers by tripling size (convert to `short` instead of `int` to
  guard against too much stack), ticket #300 (#7 & #10), props Andre
  Maute; (TODO: add some checks instead to bail out earlier?)
CODEONE: fix looping on latch crash in `c1_encode()`, ticket #300 (#8),
  props Andre Maute
CODABLOCKF: fix crash on negative overflow of `columns` (`option_2`),
  ticket #300 (#9), props Andre Maute
library: add `debug_print_escape()` helper for ZINT_DEBUG_PRINT

e1522e0808 backend: non-functional code-fiddling: format codablock.c (clang-format
+ manual); add SPDX to all files; prefix include guards with Z_;
  move vim comment to bottom; remove some trailing spaces

fab7435fac Performance improvements for linear encoding and raster output
- use fixed-length string tables (mostly) instead of (char *) pointer ones
   (saves ~40K)
 - re-use C128Table for CODABLOCKF and CODE16K
   (required removal of Stop character and extra CODE16K-only entry)
 - use pointer to destination and copy (memcpy/strcpy(), bin_append_posn())
   instead of concatenating (strcat()) (mostly)
 - replace last remaining bin_append()s with bin_append_posn();
   bin_append() removed
 - add length arg to toupper() and expand() (avoids strlen())
 - change is_sane() to use table-based flags (avoids an iteration)
 - rename lookup() to is_sane_lookup() and change to check and return posns
   and use in pointer to destination loops (avoids strcat()s)
 - remove special case PHARMA in expand() (dealt with in pharma())
 - make #define SILVER/CALCIUM/TECHNETIUM/KRSET etc static strings
 - replace strchr() -> posn()
 - CODE128: populate destination once in checksum loop; re-use and export
   some more routines (c128_set_a/b/c(), c128_put_in_set()) for sharing;
   prefix defines (SHIFTA -> C128_SHIFTA etc) and existing exported routines
 - use factor XOR toggle trick in checksum calcs (avoids branch)
 - raster.c: fill out single 1-pixel row and copy using new draw_bar_line(),
   copy_bar_line() routines; similarly in buffer_plot compare previous line &
   copy if same (same technique as used to improve non-half-integer scaling,
   significant performance increase, (c) codemonkey82);
   also done for PNG (BMP/GIF/PCX/TIFF not done)
 - raster/vector/output.c: shorten "output_" prefix -> "out_";
   sync vector to other raster changes to try to keep source files similar
 - 2of5.c: prefix "c25_"
JAPANPOST: return error if input data truncated (backward incompatible)
DAFT: max chars 50 -> 100
common.c: istwodigit() -> is_twodigit()
common.c/emf.c/output.c: use some further stripf()s (MSVC6 float variations)
library.c: new check_output_args() helper
zint.h: add BARCODE_LAST marker and use in library.c
QRCODE: remove a NOLINT (requires clang-tidy-13), one remaining
CMake: separate no-optimize from ZINT_DEBUG into new ZINT_NOOPT option
