* sm/gpgsm.c (main) <aSign,aEncr>: Uses gpgrt_fcancel on error.
--
When creating a signature or encrypting and the respective key is not
available or the user canceled the PIN entry gpgsm prints the initial
part of the message due to internal buffering in gpgrt. By using
gpgrt_fcancel we can avoid this at least as long as the data is less
than the standard buffer size (which is currently 8k). If is not a
complete solution but the best we can do easily. Outputting to the
tty is anyway more of a testing aid than for real use.
This makes use of the new gpgrt_fcancel API.

--
The model I'm using for a TPM daemon is the current scdaemon. That
includes start and stop handlers plus liveness checks and an assuan
socket generator. To avoid massive code duplication (and save me a
lot of effort), I've elected to strip this code out of call-scd.c into
a generic framework which can then be reused as is by the TPM handling
daemon.

For TPM support it is necessary to indroduce another type of shadow
key, so allow other agent functions to extract the type so they can
make the right decisions based on it.

Minor editorial changes by wk
* agent/pksign.c (do_encode_eddsa): First argument is NBITs,
so that it can support Ed448, as well as Ed25519.

for Ed448, it's only for classic curves.

That curve is a bit odd in that it does not match a common hash digest
length. We fix that here for just this case instead of writing more
general code to support all allowed cases (i.e. hash shorter than Q).

(ask_algo): Tweak mapping of ECC to OpenPGP algos
(parse_key_parameter_part): Ditto.
(generate_subkeypair): Create the subkey with the time stored on the
card.
--
This fixes two problems with generating keys from a card:
1. The key usage is now set correctly for brainpool curves.
2. The add-key and --quick-add-key commands now also take the creation
time from the time stored on the card. Without that we would need
to update the creation time and fingerprint already stored on the
card which is a no-go if another key has already been created using
that on-card key.
Note: To create a key on a card without an OpenPGP keyblock use
gpg-card.

This command is hidden because it can be used to brick a card. The

* scd/app.c (select_all_additional_applications_internal): Re-select
first app. Add arg 'ctrl'.
--
Usually keygrip based access to the Yubikey does a switching back and
forth and thus keeps the card and scdaemon's internal state in sync.
However, if we do only a listing scdaemon did not reselect the first
application (e.g. OpenPGP) after adding other applications (e.g. PIV)
and thus led to wrong info returned in a listing.
