* g10/pkclist.c (select_algo_from_prefs): Change implicit cipher
algorithm.
--
Although 3DES is still a compliant algorithm, some other software does
not consider it has compliant but also does not set preference
accordingly. Thus it is better to switch the implicit cipher algorithm
similar to what we already did with SHA-1.
Note that in GnuPG 2.3 3DES is already not anymore used here.

The original check was too strong because it is in fact compliant to
encrypt with a symmetric key and and public key. Thus decryption
should issue a compliance status.
In addition we now check that the cipher algorithms used to
symmetrically encrypt the session key are all compliant. This is
similar to our check for all public key encrypted session key packets.

This allows GPGME to return a better error message than "bad session

--
The intention of this mostly forgotten registry entry was to allow for
easy debugging of the tools. However, with the global config
files (and in 2.3 with common.conf) things are anyway better. We
disable the use for the commonly used tools so that it does not look
like calling gpg on the command line seems to block with no output if
the log server (e.g. tcp://1.2.3.4:11111) is not reachable.

With out this change we would see
gpg: cipher algorithm 'AES256' may not be used in
--compliance=de-vs mode
This is confusing because AES256 is compliant. Now we see
gpg: cipher algorithm 'AES256.OCB' may not be used in
--compliance=de-vs mode
which gives a hint on the problem.
* g10/decrypt-data.c (decrypt_data): Add arg compliance_error. Adjust
all callers. Fail on compliance error only in --require-compliance
mode. Make sure to return an error if the buffer is missing; actually
that should be an assert.
* g10/mainproc.c (proc_encrypted): Delay printing of the compliance
mode status. Consult the compliance error now returned by
decrypt_data.
--
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.
Note that this does currently not work in 2.3 due to a non-compliant
libgcrypt. We will however, backport this to 2.2.

Note that in the --encrypt and --verify cased other checks may kick in

The more specific CLFAGS should come first so these are picked up

specific location.

--
Avoiding extra hash contexts speeds up CFB/MDC decryption quite
a lot. For example, decrypting symmetric-key AES-256 encrypted
4 GiB file from RAM to /dev/null sees ~3.4x speed increase on
AMD Ryzen 5800X:
AES256.CFB encryption: 783 MB/s
AES256.CFB decryption: 386 MB/s (before)
AES256.CFB encryption: 1.3 GB/s (after patch)
Note, AEAD is still significantly faster:
AES256.OCB encryption: 2.2 GB/s
AES256.OCB decryption: 3.0 GB/s

Due to reading the list of options from the argparser of the
component, we had no more information about the pseudo options and
thus could not emit them. Well, there is just one pseudo option right
now, but with this change we have a generalized concept for them:
Pseudo options are used to convey information from a component to
gpgconf; for example build-in values.

There is one important use case for this: For systems configured
globally to use de-vs mode, Ed25519 and other key types are not
allowed because they are not listred in the BSI algorithm catalog.
Now, our release signing keys happen to be Ed25519 and thus we need to
offer a way for users to check new versions even if the system is in
de-vs mode. This does on purpose not work in --batch mode so that
scripted solutions won't accidently pass a signature check.
