AZTEC: add almost optimal encoding algorithm, previous algorithm

Browse Source 
available via "--fast" (input_mode |= FAST_MODE) (ticket #347);
  add new option "--azfull" (option_3 = ZINT_AZTEC_FULL) to only
  consider Full symbols (not Compact ones) on automatic sizing
GUI: adjust Aztec tab to show feedback by selecting combos and
  shorten message to just actual ECC;
  grpCodabar min width
library: debug source input dump 200 -> 2000
common: some code fiddling (c -> ch, flg -> flag)
backend_tcl: add "-azfull" option & make capitalization of
  help more consistent
general: remove some trailing whitespace
manual: make Aztec ECCs more precise, i.e. ">=" rather than ">"
  (similarly in GUI)
CLI: code fiddling c -> opt

Compact symbols can be excluded from consideration on automatic sizing by
specifying `--azfull` (API `symbol->option_3 = ZINT_AZTEC_FULL`).
Aztec Code supports ECI encoding and can encode up to a maximum length of
approximately 3823 numeric or 3067 alphabetic characters or 1914 bytes of data.
A separate symbology ID (`BARCODE_HIBC_AZTEC`) can be used to encode Health
Industry Barcode (HIBC) data.
For a faster but less optimal encodation, the `--fast` option (API `input_mode
|= FAST_MODE`) may be used.
Aztec Code supports Structured Append of up to 26 symbols and an optional
