PDF417: fix cols/rows calculation to require multiple <= 928 codewords;

Browse source 
add specify rows option (option_3) (#204);
  warn if cols increased from specified (back-incompatible);
  move table definitions from "pdf417.h" to new "pdf417_tabs.h" and
  make INTERNAL_DATA and share with composite.c (saves ~10K);
  prefix routines and tables with "pdf_";
  some small performance improvements through if/elses, pdf_textprocess()
  & pdf_numbprocess() loop simplifications
MICROQR: fix debug access crash on printing non-NUL-terminating binary
DATAMATRIX: fix missing ++ from "[tp]" at C40/TEXT EOD processing of GS1
  (though probably never reached); use "[tp++]" throughout
Add const to static tables missing it and also to some variables
Change "debug" -> "debug_print" throughout
