The requirement of using --card-status on the first use of card on a

The problem was found by Jan Bee and gniibe proposed the used fix.
Thanks.
This bug can't be exploited: Only if the announced length of the
notation is 21 or 32 a memcmp against fixed strings using that length
would be done. The compared data is followed by the actual signature
and thus it is highly likely that not even read of unallocated memory
will happen. Nevertheless such a bug needs to be fixed.

--
Only report support for the hkps scheme when GnuPG / dirmngr
has been built with a TLS library.
This helps debuging and enable the user to detect whether support
for hkps is included by doing a
`gpg-connect-agent --dirmngr 'keyserver --help' /bye`.
Currently hkps will be listed as a supported scheme but trying to
add a keyserver using it will silently fail.
As a digression, https is never listed as a valid scheme.

(test_openpgp_oid_to_str): Add test cases.
--
The code has an obvious error by not considering invalid encoding for
arc-2. A first byte of 0x80 can be used to make a value of less then
80 and we then subtract 80 from that value as required by the OID
encoding rules. Due to the unsigned integer this results in a pretty
long value which won't fit anymore into the allocated buffer.
The fix is obvious. Also added a few simple test cases. Note that we
keep on using sprintf instead of snprintf because managing the
remaining length of the buffer would probably be more error prone than
assuring that the buffer is large enough. Getting rid of sprintf
altogether by using direct conversion along with membuf_t like code
might be possible.

This avoids a dead path in the argparse code.
It's not clear that this is needed, however, since
ARGPARSE_AMBIGUOUS_COMMAND is never actually used in the code.
Another approach would be to trim out ARGPARSE_AMBIGUOUS_COMMAND
entirely.
