- remove command line option '--card-driver';
- instead force driver 'cardos' and fail if card is not a CardOS card
- overhaul option parsing
- remove unused variable 'long_optind'
- bail out with usage message on all unknown/unhandled args
- correctly terminate option parsing (no infinite loop)
Extend cardos-tool the same way opensc-explorer was extended. I.e.
treat the question mark given as argument to option '--card-driver'
special: list all available drivers instead of stupidly bailing out.
In contrast to opensc-tool and opensc-explorer, which are card-agnostic,
I am not sure whether the option '--card-driver' makes sense on this
card-specific tool.
* get rid of hard-coded markup like e.g. { ... | ... } or [ ... ]
in favour of DocBook's proper tags
* use tags better matching the purpose,
e.g. use <filename class"directory"> instead of <command> for directories
* improve consistency in <replaceable>s
