Having always the single byte in the packet data than to store and

This uses a revised format which is more aligned with the usual

support for handling two keygrips and checking both of them in a -K
listing. There is also only ky768_bp384 as fixed algorithm for now.
No passphrase for the Kyber part of the dual algorithm is on purpose.
A test was done using
gpg --quick-gen-key pqc1 nistp256

gpg -v --quick-add-key <fingerprint> kyber
which creates a v5 subkey on a v4 primary key. A second test using
gpg --quick-gen-key pqc2 Ed448
followed by a --quick-add-key created a v5 key with a v5 subkey.

The actual case here is that we fail hard if a message has been AEAD
encrypted with one AEAD capable key and also with one passphrase. In
general the preference system takes care of not using AEAD if one
recipient's key does not support it. However, if the sender uses her
own AEAD-capable key _and_ a passphrase the message will be AEAD
encrypted. This change allows to decrypt that anyway along with a
warning message.

PKA (Public Key Association) was a DNS based key discovery method
which looked up fingerprint by mail addresses in the DNS. This goes
back to the conference where DKIM was suggested to show that we
already had a better method for this available with PGP/MIME. PKA was
was later superseded by an experimental DANE method and is today not
anymore relevant. It is anyway doubtful whether PKA was ever widely
used.

This is is the second part to support the new Key Block subpacket.
The idea is that after having received a signed mail, it is instantly
possible to reply encrypted - without the need for any centralized
infrastructure.
There is one case where this does not work: A signed mail is received
using a specified signer ID (e.g. using gpg --sender option) and the
key block with only that user ID is thus imported. The next time a
mail is received using the same key but with a different user ID; the
signatures checks out using the key imported the last time. However,
the new user id is not imported. Now when trying to reply to that
last mail, no key will be found. We need to see whether we can update
a key in such a case.

(key_check_all_keysigs): De-duplicate on a per-block base.
--
The key_check_all_keysigs first does a detection of duplicate
signature. This is done over all signatures at once. The problem
here is for example:
key
uid_1
sig_uid_1.1
sig_uid_1.2
subkey_1
sig_sub_1.1
subkey_2
sig_sub_2.1
sig_sub_2.2 (duplicate of sig_sub_1.1)
Now the de-duplication deletes the first signature and keeps the
second. That works in most cases for foreign signature on userids but
in the above constellation the code simply removes sig_sub_1.1 so that
subkey_1 has no binding signature anymore. In a later step during
import the missing binding is detected and subkey_1 is removed because
it is not anymore valid. The sig_sub_2.2 will also be removed later
because it does not check out for subkey_2 (that is as expected).
The fix is to let the de-duplication work only on blocks (ie. within
the signatures of a user id or a subkey). This will not detect all
duplicates but that does not harm because later steps will detect and
remove them.
In the above case (with this patch applied) the second phase of
key_check_all_keysigs will reorder key signatures and move the
duplicate sig_sub_2.2 directly after sig_sub_1.1. This duplicates the
signature and for cleanness we should kick the de-duplication process
again. This will be done with a followup patch.

Scripts used to rely on the "User ID not found" string even in the
--with-colons listing. However, that is not a good idea because that
string is subject to translations etc. Now we have an explicit way of
telling that a key is missing. For example:
gpg --list-sigs --with-colons | \
awk -F: '$1=="sig" && $2=="?" {if($13){print $13}else{print $5}}'
Prints all keyids or fingerprint of signing keys for which we do not
have the key in our local keyring.

This patch introduced the framework to store meta data for keys and
user ids in the keyrings/keyboxes. Ring trust packets are
implementation defined and have always been used in gpg to cache the
signature verification status.
Ring trust packets are only exported with the export option "backup"
and only imported with the import option "restore".
The new code uses a cleaner way to handle the ring trust packets: When
the parser reads a ring trust packet and the previously read packet
matches the type of that ring trust packet, the information is stored
in that previously read packet (signature, user id, or primary key)
and the next packet is read immediately. Thus only the parser sees
the ring trust packets. Ring trust packets are written by using the
new function build_packet_and_meta instead of build_packet. That
function writes a ring trust packet when the needed information is
available.
As a side-effect of this patch the signature status cache works again
and "gpg --check-sigs" is thus much faster.

The output
gpg: textmode signature, digest algorithm SHA256, key algorithm rsa2048
showed the pubkey algo of the primary key which was surprising.
Changed to print the algo of the subkey used for verification.
