--
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/packet.h (PUBKEY_USAGE_RENC): New.

See draft-koch-openpgp-2015-rfc4880bis-00 for the current version.
Actually these flags have been in the draft for years now. This patch
is a first step to make use of them.
* 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
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.
