* localize variables
* print errors to stderr
* release allocated resources
* return error code on error - improve non-interactive use
* do not show help on unknown commands when used non-interactively
* make 'interactive' a global variable
* set it when opensc was called with the SCRIPT argument
* document the behaviour in the manual page
Make interactive a global variable and set it in main.
When arguments are given, compare them like ambguous_match() does,
and show the matching ones only.
Add documentation of the 'help' command to the manual page.
In main loop on multiple matches, show help on matching commands only.
* most importantly: immediately return success on exact match
- this allows one command to be a prefix of another one
- it fixes the long-standing breakage between 'find' and 'find_tags'
* fail on second prefix-only match instead of waiting until the end
* check all parameters
* add comments
* inform caller on whether the match was ambiguous or there was no match
* move printing error messages to processing loopt in main()
Accept a file name as a second argument to the 'random' command
to allow storing the generated random bytes to the file given.
Forbid writing binary data to stdout in interactive mode.
* limit buffer to SC_MAX_EXT_APDU_BUFFER_SIZE
* fix buffer length calculation to correctly calculate the available space
* add length checks when parsing passed data into buffer
* consistently show ellipsis for repeatable arguments as 3 dots
* embrace alternative mandatory arguments with curly braces
* use hyphens instead of spaces within non-literal arguments
for improved alignment with the manual page
Let sc_get_challenge() do sc_lock() and loop through the card driver's
get_challenge() until enough bytes were collected. The card driver's
get_challenge() now returns the number of bytes collected (less or equal
than requested) or an error code.
- Allow more code re-use.
- PIV driver now uses ASN.1 parser for reading the random bytes
opensc-explorer.c:1727:8: warning: comparison of integers of different signs:
'int' and 'size_t' (aka 'unsigned long') [-Wsign-compare]

Some cards (e.g., BELPIC) have a hardcoded file length that does not
match the actual file length (e.g., 65535 bytes), and simply return the
data that is actually on the card when asked.
It is useful to still be able to do an ASN.1 decode in that case.

'PACE' is extremely card specific protocol and has not to be ostensibly
present in the common part of OpenSC:
* currently in OpenSC there is no card driver that supports or uses this protocol;
* amazing content of the common 'sc_perform_pace' -- beside the verbose logs
the only substantial action is to call the card/reader specific handler.
According to the current sources and the pull request 83
this 'common' procedure is called by the card driver or
card specific tool/operation.
* currently the 'PACE' can be thouroghly tested only by one person (Frank Morgner),
and only using the OpenSSL patched with the PACE specific patch.
So, at least a dedicated configuration option could be introduced when comiting PACE to the common part.
* common 'sc_perfom_pace' has the same role as the 'initialize-SM' handler of the existing SM framework
and can be implemented as card specific SM, as the others cards do.
This confirmed by Frank Morgner, the author of PACE commits and nPA card driver, himself.

Harmonize the allowed PIN length in CHANGE & UNBLOCK with the one in VERIFY,
making sure they are large enough for OpenPGP, which allows up ro 32 characters,
and giving additional security margin for other cards.
In VERIFY, allow the user to enter the PIN unteractively if it was not given
on the command line, and if the card reader does not support PIN input.
If it was not given on the command line and the card reader supports PIN input,
then the bahaviour is unchanged: enter PIN via card reader.
