Add Structured Append support for AZTEC, CODEONE, DATAMATRIX, DOTCODE,

Browse source 
GRIDMATRIX, MAXICODE, MICROPDF417, PDF417, QRCODE, ULTRA
DOTCODE: use pre-calculated generator poly coeffs in Reed-Solomon for
  performance improvement
PDF417/MICROPDF417: use common routine pdf417_initial()
GUI: code lines <= 118, shorthand widget_obj(),
  shorten calling upcean_addon_gap(), upcean_guard_descent()
various backend: var name debug -> debug_print
