CODE128: optimize for extended ASCII as well using techniques from

Browse Source 
BWIPP minimal encoding by Bue Jensen (BWIPP PR #278);
  new extra escape `\^@` to turn off manual switching
zint.h: increase `symbol->text` size 200 -> 256 (means that for
  the moment can no longer generate ZINT_WARN_HRT_TRUNCATED)
GS1_128/GS1_128_CC: warn if READER_INIT option used
CODE16K: move `c16k_set_a/b/c()` routines from "code128.c" and
  rename `c16k_` (also `C128_` defines to `C16K_`)
common: make `itoc()` simple macro which adds '0' (>= 10 now ':',
  ';' etc) and adjust `expand()` accordingly for slight speed-up
general: EXTRA_ESCAPE_MODE now implies ESCAPE_MODE
tests: update BWIPP to latest and enable CODE128AB ("suppressc");
  new test args '-n' (exclude func) and '-m' (match func)
