This has been tested with gpgsm and RSA keys. For ECC keys only
partly tested using the sample OpenPGP nistp256 and nistp384 keys
because gpgsm does not yet support ECC certificates and thus we can't
write the certificates to the cert object after a writekey. Note that
they nevertheless show up in "gpgcard list" because gpg-card searches
for them in gpg and gpgsm. However, this does not work completely.

Non-OpenPGP compliant keys now show a warning flag on the sec or pub

sec cv25519 2019-01-30 [INVALID_ALGO]

uid [ultimate] ffffff
Instead of showing the usage flags "[CE]". Without this patch only
the error message is printed and the reason for it was not immediately
obvious (cv25519 is encryption only but we always consider the primary
key as having the "C" flag).

--
A certificate with algorithm sha1WithRSAEncryption can be de-vs
compliant (e.g. if the next in the chain used sha256WithRSAEncryption
to sign it and RSA is long enough) but flagging it as such is useless
because that certificate can't be used because it will create
signatures using the non-compliant SHA-1 algorithm.
Well, it could be used for encryption. But also evaluating the
key-usage flags here would make it harder for the user to understand
why certain certificates are listed as de-vs compliant and others are
not.

It's best to keep same data format by libgcrypt.

This is a convenience options for software which directly connects to
gpg-agent and thus needs to new the socket. By using --show-socket
along with --launch that software can also autostart the agent or the
dirmngr. Without this two calls to gpgconf would be required.
Actually the same behaviour can be achieved by running
gpg-connect-agent to query the running gpg-agent's socket via GETINFO.
The gpg-connect also makes sure that the agent is started. This is
not anymore suggested because gpgconf shall in future be used for all
such things.

This handling is not mondatory, but it's better to do so, because

User interaction status should be reset at open time. The status
should be reset when the session is closed/stopped. In practice,
since cleanup routine in a driver may not be called properly, it's
good to submit SET_INTERFACE at open time.

* sm/certreqgen.c (create_request): Fix for certmode.
--
When using an existing key from a card for certificate signing (in
contrast to the default of generating a CSR), the code tried to use
the same key for signing instead of the Signing-Key parameter. It is
perfectly okay to use the regular signing path via gpg-agent for
certificate creation - only self-signed certificates with a key on the
card require the direct use of the card key (via "SCD PKSIGN").
