/MAILMARK_4S/PDF417/MSI_PLESSEY/QRCODE/RMQR/TIF/ULTRA/USPS_IMAIL:
lessen storage of some tables by using least integral size
required (saves ~3K); reformat some tables, comments
AUSPOST/AZTEC: remove unnecessary int casts on array indexing
CODE11/CODE39: move start/stop chars into one entry in tables to
save a few bytes; some reformatting, comments
CODEONE: add `c1_` prefixes
common: more precise compiler/version checks
composite: add `cc_` prefixes; UINT -> unsigned short; use
`sizeof()` instead of `strlen()` for `in_linear_comp` static;
some reformatting, comments
EMF: use table instead of string for `ultra_chars[]`
GIF: remove unnecessary cast
library: use `sizeof()` instead of `strlen()` for static;
add `consts` to `escape_char_process()` & use unsigned for `ch`
DBAR: use `dbar_`, `dbar_ltd_`, `dbar_exp_` prefixes
docs: update pandoc version
