general: prefix all INTERNAL funcs/tables with zint_, except

Browse Source 
those in "backend/common.h", which are prefixed by `z_` - makes
  symbol clashes more unlikely when zint is statically linked
  (ticket #337, props Ulrich Becker)
DOTCODE: fix padding allowance (10 -> 52 - probable max 35) to
  cover cases with large no. of columns requested and little data,
  to prevent `codeword_array` buffer overflow
AZTEC/CODEONE: some code fiddling
general_field: prefix defines with `GF_`, shorten static funcs
  prefix `general_field_` -> `gf_`
