CODE128: reduce extended latch cut-off from 5 to 4 for better encodation in certain cases (and no pessimizations found so far), props lyngklip (BWIPP); fix extended char latching when exactly 3 extended chars at end; count code set C (not digits) in loop deciding when to shift/latch to extended for better estimate AZTEC: return warning if ECC < 5% (due to bit-stuffing when version given); return error if > 22 layers (Zint 26) for Reader Initialisation symbol requested for better error message AZTEC/HANXIN/QRCODE: consolidate different ECC data size tables into one indexed by ECC DBAR_EXP: check for reduced length <= 77 up front for better error message HANXIN: use `malloc()` rather than `z_alloca()` for large binary array QRCODE: `ecc_level` now 0-based (not 1-based) MICROQR: consolidate different version end routines into one `microqr_end()` and use new `microqr_data` table to simplify code MICROPDF417: use table for max codewords per column library: centralize all error messages using new `errtxt()`, `errtxtf()`, `errtxt_adj()` funcs that protect `symbol->errtxt` from overflow, & try to make error messages more consistent thru-out, adding more feedback info to many, & use positional args "%n$" in prep for l10n (maybe); `is_sane/is_sane_lookup()` -> `not_sane/not_sane_lookup()`, returning 1-based position (zero on failure) instead of bool; `long` ints -> plain `int` (except those dealing with `ftell()`, `fread()` etc) as depend on int being 32-bits already GUI: in "grpDATF.ui" use "PlainText" rather than "RichText" for tracker ratio examples as height of text messing up sometimes manual: clarify Codablock-F length maximum & add examples docs: README: pandoc 3.5, Ubuntu 24.04 CMake: use "-Wpedantic" for Clang only as GNU complains about `errtxtf()` positional args "%n$"
