`BARCODE_EAN_5ADDON`, `BARCODE_EAN13`, `BARCODE_EAN8_CC` and
`BARCODE_EAN13_CC` as replacements for `BARCODE_EANX`,
`BARCODE_EANX_CHK` and `BARCODE_EANX_CC` and use in CLI/GUI
(`BARCODE_EANX` etc. marked as legacy)
- For EAN/UPC accept space as alternative add-on separator to '+',
and accept GTIN-13 format with & without 2-digit or 5-digit
add-on (no separator)
- Buffer length of member `errtxt` in `zint_symbol` extended 100
-> 160 (will be sufficient for eventual translation and
gs1-syntax-dictionary errors hopefully)
- UPC-E: warn if first digit of 7 (or 8 if check digit given) not
'0' or '1'
- manual: update for new EAN symbologies and mention EANX now
legacy but still supported
followed by digit (ignore 2nd byte of FNC4 when categorizing
Code C characters)
- New `ZBarcode_Cap()` flag `ZINT_CAP_BINDABLE`, differentiated
from `ZINT_CAP_STACKABLE`, and new Qt Backend method
`isBindable()`
- CLI: fix `separator` check to use new `ZINT_CAP_BINDABLE` instead
of `ZINT_CAP_STACKABLE`
- ZBarcode_Cap: add missing symbologies to `ZINT_CAP_BINDABLE` (was
`ZINT_CAP_STACKABLE`)
- DOTCODE: pad rows if given number of columns instead of failing
if rows below min (5)
- DBAR/composites: ensure stacked symbologies and composites are
not stacked (set `symbol->rows` to 0)
- test suite: move `test_perf` routines into single test
"test_perf";
new "test_random" (based on "test_bwipp") to test various
symbologies with random binary - discovered CODABLOCKF bug;
expand "test_bwipp"
manual: Feeback: mention AZTEC -1 meaning min & MICROPDF417:
doc new `ZINT_CAP_BINDABLE`
general: various code fiddlings and re-formattings
