for the feature is PDF signature checking where the PDF specs require
that the detached signature is padded with zeroes.

gpg: Prepare to accept shorter OIDs for ed25519 and cv25519.
* common/openpgp-oid.c (oidtable): Add them.
(oid_ed25519_v5, oid_cv25519_v5): New.
(openpgp_oidbuf_is_ed25519): Take new OID in account.
(openpgp_oidbuf_is_cv25519): Ditto.

ed25519 is used in GnuPG and other implementations since 2015 and thus
we can't simply switch to the shorter OIDs.  However, we have not
widely used them with v5 keys (only ed448 forced the use of v5) and
thus it might be possible to use the new OIDs with v5 keys.

Note that Libgcrypt supports the new OIDs even in 1.8.

common: Slight redefinition of nvc_get_boolean.
* common/name-value.c (nvc_get_boolean): Rewrite.
--

The function may now return a positive or negative number instead of
just 1 for true.  All callers were already prepared for this.

gpg: Replace --override-compliance-check by a real fix.
* 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.

Note that this patch also introduces a compression check for signing
which was never done in the past.
