--
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.

* scd/app.c (select_all_additional_applications_internal): Re-select

--
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.

I did some test against
Governikus_Signer: 2.9.2.0
MCard security Provider: 2.4.0
Algorithm catalog from: 05.12.2019
using a Signature Card v2.0 and a nistp256 certificate. Encrypting
with Governikus used the stdDH-sha1kdf scheme which we can now
decrypt. Encrypting with GPGSM uses for that curve the recommended
scheme sha256kdf but Governikus was not able to decrypt this (no
usable error message). Encrypting using stdDH-sha1kdf with GPGSM by
using the new --debug-force-ecdh-sha1kdf option showed that
Governikus was able to decrypt this.
FWIW: RFC5753 (Use of Elliptic Curve Cryptography (ECC) Algorithms)
has this requirement:
Implementations that support EnvelopedData with the
ephemeral-static ECDH standard primitive:
- MUST support the dhSinglePass-stdDH-sha256kdf-scheme key
agreement algorithm, the id-aes128-wrap key wrap algorithm, and
the id-aes128-cbc content encryption algorithm; and
which Governikus seems not to fulfill.
