The scd WRITEKEY command for OpenPGP cards missed proper support to
aautomagically switch key attributes based on the new key. We had
this only in GENKEY.
GnuPG-bug-id: 6378
* common/compliance.c (gnupg_pk_is_allowed): Handle EdDSA.
* g10/gpg.c (oOverrideComplianceCheck): Remove.
(opts): Turn --override-compliance-check into a dummy option.
* g10/options.h (opt): Remove override_compliance_check.
* g10/sig-check.c (check_key_verify_compliance): Remove use of that
option.
--
The introduction of --override-compliance-check actually hid the real
cause for the signature verification problem in de-vs mode for the
Ed25519 key. The real fix is to handle the EdDSA algorithm in
gnupg_pk_is_allowed.

This function is intended as a more general version of gpg's
pubkey_string function. It has the advantage to avoid mallocs and
uses static table of algorithm strings instead. There should be only
a few dozen of such strings (if at all) and thus all those allocations
we do internally in gpg's pubkey_string and the static buffers all
over the place are not too nice.

This extends the long available OCB and EAX decryption feature. Due
to the meanwhile expired patent on OCB there is no more reason for
using EAX. Thus we forcefully use OCB if the AEAD feature flag is set
on a key.
In GNUPG mode new keys are now created with the AEAD feature flag set.
Option --rfc4880 is one way to disable this.

Note that for this LTS version we now print g10 Code as the first

The w32_try_mkdir was once introduced for WindowsCE and unfortunately
at a too brief inspection it looks like it does the utf8->wchar
conversion. Which it does not. Thus I obviously never tested the
switch to from APPDATA to LOCAL_APPDATA with a non-ascii account name.
That might have been due to the use of the very same code for the
homedir - but there is other code in gpg to create the homedir; thus a
failure here is mostly fixed later.
The missing error diagnostic was - and is - on purpose to avoid such
error messages due to a race between several running gpg instances.
