This patch solves two purposes:
- We write a note that the ADSK key was used for decryption
- We avoid running into a
"oops: public key not found for preference check\n"
due to ADSK keys. The error is mostly harmless but lets gpg return
with an exit code of 2.

* g10/getkey.c (lookup): Skip keys with unknown algos.
--
If the local store has private keys with an algorithm not supported by
thi version of gpg, gpg used to bail out. Thus decryption of proper
messages was not possible. This fix skips such secret keys.
* g10/options.h (COMPAT_VSD_ALLOW_OCB): Remove.

* sm/encrypt.c (encrypt_dek): Always allow ecc encryption.

Both feature are meanwhile approved in de-vs mode thus there is no
more need for the flags.
* g10/keygen.c (print_key_flags): Print "RENC" if set.
(ask_key_flags_with_mask): Remove RENC from the possible set of
usages. Add a direct way to set it iff the key is encryption capable.
--
This could be done by using "set your own capabilities" for an RSA
key. In fact it was always set in this case.

* g10/keygen.c (card_store_key_with_backup): Use that force value.
--
This was a regression in 2.2.42. We took the easy path to fix it by
getting the behaviour back to what we did prior to 2.2.42. With GnuPG
2.4.4 we use an entire different and safer approach by introducing an
ephemeral private key store.

* g10/sign.c (do_sign): Skip compliance check for revocation certs.
--
It just does not make sense to inhibit the creation of revocations
depending on the compliance mode. We do this only for key revocation
but not for another kind of revocation because the rationale for uid
or subkey revocation is more complicated to explain.
* g10/call-agent.c (agent_get_passphrase): Call
assuan_begin_confidential and assuan_end_confidential.
* sm/call-agent.c (gpgsm_agent_ask_passphrase): Ditto.

The drawback of this solution is that we don't see any IPC lines from

If a key is searched by fingerprint or keyid and it happens that this
is an ADSK (subkey with the RENC usage), we need to skip this key
because it is not the key we actually want to encrypt to. The actual
ADSK key is taken later by looking at all subkeys of the actual
selected key.

This used to work using the gpg-agent: learn we called at "save" time.
However, the recent change inhibited the creation of a shadow key by
learn if a regular key still exists. Now we do an explicit delete key
at save time. This syncs the behaviour with the description of the
man page.

GnuPG-bug-id: 6395
This patch handles ADSK keys and encrypts to them. It does not yet
allow the creation of them. We backport this from master early to get
this part of the code out into the field.
* g10/parse-packet.c (parse_signature): Parse the ISSUER_FPR subpacket
and use that to get the keyid.
--
Because ADSKs are created w/o the issuer subpacket (despite that this
is still a v4 signature) we need to get the key id from the
issuer_fpr. This does not harm and we still fallback to the the
issuer. Note that for ease of future backporting we also take v5
fingerprints into account.

* g10/gpg.c (main): Replace setmode by es_set_binary and use only when
needed.
--
It is better to use our es_set_binary than to use a Windows specific
method which still worked but is fragile because estream might be
changed. We now set binary only when needed. Note that it does not
harm to call es_set_binary more often than needed.
* g10/gpg.c (main): Add that hack.
--
This is an yet undocumented hack to allow printing hex encoded random
number with gpg. The level is forced to be 1 which is is good for
almost all uses. Note that --armor is ignored.

The introduction of --override-compliance-check actually hid the real
