gpg: Emit an ERROR status as hint for a bad passphrase.
* g10/mainproc.c (proc_symkey_enc): Issue new error code.
(proc_encrypted): Ditto.
--

This allows GPGME to return a better error message than "bad session
key" to the user.  Technically we could get run into these errors also
in other cases but this more unlikley.  For the command line use we
don't do anything to not change the expected output of the command
line interface.

w32: Do no use Registry item DefaultLogFile for the main tools.
* g10/gpg.c (main): Set LOG_NO_REGISTRY.
* sm/gpgsm.c (main): Ditto.
* tools/gpg-connect-agent.c (main): Ditto.
* tools/gpgconf.c (main): Ditto.
(show_other_registry_entries): Print "DefaultLogFile".
--

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.

* g10/misc.c (openpgp_cipher_algo_mode_name): New.
* g10/decrypt-data.c (decrypt_data): Use function here.
--

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.

gpg: Allow decryption of symencr even for non-compliant cipher.
* 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.

The more specific CLFAGS should come first so these are picked up
first.  We really should improve the build system to enforce this
rule.  In particular /usr/local/include should come after any more
specific location.

g10: Avoid extra hash contexts when decrypting MDC input
* g10/mainproc.c (mainproc_context): New member
'seen_pkt_encrypted_mdc'.
(release_list): Clear 'seen_pkt_encrypted_mdc'.
(proc_encrypted): Set 'seen_pkt_encrypted_mdc'.

'seen_pkt_encrypted_mdc'.
(proc_plaintext): Do not enable extra hash contexts when decrypting
MDC input.
--

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

GnuPG-bug-id: 5341,5800

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.

This is a combined backport of patches to master.

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.

With this patch the former patch to use ReadConsoleW and WriteConsoleW

We now rely on the dirmngr to parse the keyserver specs.  Thus a bad

that dirmngr had stricter tests.

In contrast to a search via keyserver_import_ntds the older
keyserver_import_name used a full match of the provided name despite
that it is only called with an addr-spec (mbox).  Due to the mode the
pattern send to dirmngr was prefixed with a '=' and thus dirmngr used
an exact search;.  This did only work for provided user ids like
"foo@example.org" but not for "<foo@example.org>" or
"Foo <foo@xample.org>".  The old code dates back to 2010.

This change makes it easy to start working with gnupg: Just insert the
smartcard or token provided to you and the first time you sign a
message the public key associated with the current card will be
imported and everything is set without any configuration.

This works only with an LDAP directory because it can be expected that
the public key has been put into the LDAP during card personalization.
Of course an LDAP server needs to be configured; in a Windows AD
domain this can be a mere "keyserver ldap:///" in dirmngr.conf.  Other
configured keyservers are ignored.

Requirements for the card driver: The $SIGNKEYID attribute must exists
and a query for the KEY-FPR attribute needs to return the OpenPGP
fingerprint for that key.  This is currently supported for OpenPGP
cards and certain PKCS#15 cards.

I can be assumed that configured LDAP servers are somehow curated and
not affected by rogue key signatures as the HKP servers are.  Thus we
can allow the import of key signature from LDAP keyservers by default.

xdg-open spawns the user's preferred image viewer and then exits.

otherwise by the time the actual image viewer is started the file
doesn't exist any more.

This will eventually allow us to declare Libgcrypt 1.9 to be de-vs
