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
in ttyio.c are kind of superfluous because the ANSI version of these
functions are also able to read/write UTF-8 directly given the console
code page has been set correctly.  However, this seems to work only
with recent versions of Windows-10.

This patch actually removes the current globing using a mingw

With the new option pasrer we used "UNKOWN" in this case.  The problem

~/.gnupg/.

get_default_configname was not anymore in use because its function is
part of the new option parser.

but without changing all functions names to gpgrt.  Instead we use
wrapper functions which, when building against old Libgpg-error
versions, are implemented in argparse.c using code from the current
libgpg-error.  This allows to keep the dependency requirement at
libgpg-error 1.27 to support older distributions.  Tested builds
against 1.27 and 1.40-beta.

Note that g13-syshelp does not anymore default to --verbose because
that can now be enabled in /etc/gnupg/g13-syshelp.conf.

* common/sysutils.c (gnupg_fopen) [W32]: Use _wfopen if needed.   Use

The config files in 2.2 are still read using fopen - we need to change
this to allow Unicode directory names.  There is also one case where
files are written using the old fopen.  The new option parser in 2.3
does not have this problem but at some places fopen is also still used.

gpg: Switch to AES256 for symmetric encryption in de-vs mode.

mode.
* g10/encrypt.c (setup_symkey): Add extra compliance check.
(encrypt_simple): Avoid printing a second error oncplinace failure.
--

Because we used the RFC4880 mode as base for the de-vs mode we got
3DES as symmetric encryption algorithm.  With the default gnupg mode
that was already used.  The new extra compliance checks are added to
detect whether a --personal-cipher-preference or --cipher-algo option
tried to override the algorithms.  They are still possible but now
non-compliant algorithms will throw an error.

Manual testing can be done with commands like this:

  gpg --no-options --compliance=de-vs \
   --personal-cipher-preferences "S1 S7" \
   --pinentry-mode loopback -v --passphrase abc -ac </etc/motd

Here the command fails due to IDEA (S1) being the preferred cipher
algorithm.  Using "--s2k-digest-algo SHA1" instead of
--personal-cipher-preferences will also fail.

This patch adds support for a to be proposed OpenPGP ferature:

  Introduce the Key Block subpacket to align OpenPGP with CMS.

  This new subpacket may be used similar to the CertificateSet of
  CMS (RFC-5652) and thus allows to start encrypted communication
  after having received a signed message.  In practice a stripped down
  version of the key should be including having only the key material
  and the self-signatures which are really useful and shall be used by
  the recipient to reply encrypted.

  #### Key Block

  (1 octet with value 0, N octets of key data)

  This subpacket MAY be used to convey key data along with a signature
  of class 0x00, 0x01, or 0x02.  It MUST contain the key used to create
  the signature; either as the primary key or as a subkey.  The key
  SHOULD contain a primary or subkey capable of encryption and the
  entire key must be a valid OpenPGP key including at least one User ID
  packet and the corresponding self-signatures.

  Implementations MUST ignore this subpacket if the first octet does not
  have a value of zero or if the key data does not represent a valid
  transferable public key.

This new command is a shortcut for

  --auto-key-locate nodefault,clear,wkd,... --locate-key

and uses the default or configured AKL list but does so without local.

gpg: Set some list options with --show-keys
* g10/gpg.c (main): Set some list options.
--

The new command --show-keys is commonly used to check the content of a
file with keys.  In this case it can be expected that all included
subkeys and uids are of interested, even when they are already expired
or have been revoked.

Using

remove some diagnostic cruft in this case.

gpg: Remove MDC options
* g10/gpg.c: Turn options --force-mdc, --no-force-mdc, --disable-mdc
and --no-disable-mdc into NOPs.
* g10/encrypt.c (use_mdc): Simplify.  MDC is now almost always used.
* g10/cipher.c (write_header): Include extra hint and make
translatable.
* g10/options.h (struct opt): Remove fields force_mdc and disable_mdc.

--

The MDC is now always used except with --rfc2440 which will lead to a
a big fat warning.

This is a stripped down version of commit
253e8bdd9014cbe6dc06adce9d9dd2f8f4b31709 which could not directly be
applied due to the AEAD mechanisms there.

gpg: Relax printing of STATUS_FAILURE.
* g10/gpg.c (g10_exit): Print STATUS_FAILURE only based on passed
return code and not on the presence of any call to log_error.
--

This fixes an actual regression in GPGME where FAILURE is considered
for example by a signature verify operation.  The operation will simply
fail and not just record that that a signature could not be verified.
In particular for files with more than one signature a log_error if
often called to show that a pubkey is missing for one of the
signatures.  Using that log_error is correct in that case.

* g10/gpg.c (wrong_args): Bump error counter.
(g10_exit): Print a FAILURE status if we ever did a log_error etc.
(main): Use log_error instead of log_fatal at one place.  Print a
FAILURE status for a bad option.  Ditto for certain exit points so
that we can see different error locations.
--

This makes it easier to detect errors by tools which have no way to
get the exit code (e.g. due to double forking).

e6f84116ab gpg: default to --no-auto-key-retrieve.
* g10/gpg.c (main): remove KEYSERVER_AUTO_KEY_RETRIEVE from the
default keyserver options.
* doc/gpg.texi: document this change.
--

This is a partial reversion of
7e1fe791d188b078398bf83c9af992cb1bd2a4b3.  Werner and i discussed it
earlier today, and came to the conclusion that:

 * the risk of metadata leakage represented by a default
   --auto-key-retrieve, both in e-mail (as a "web bug") and in other
   contexts where GnuPG is used to verified signatures, is quite high.

 * the advantages of --auto-key-retrieve (in terms of signature
   verification) can sometimes be achieved in other ways, such as when
   a signed message includes a copy of its own key.

 * when those other ways are not useful, a graphical, user-facing
   application can still offer the user the opportunity to choose to
   fetch the key; or it can apply its own policy about when to set
   --auto-key-retrieve, without needing to affect the defaults.

Note that --auto-key-retrieve is specifically about signature
verification.  Decisions about how and whether to look up a key during
message encryption are governed by --auto-key-locate.  This change
does not touch the --auto-key-locate default of "local,wkd".  The user
deliberately asking gpg to encrypt to an e-mail address is a different
scenario than having an incoming e-mail trigger a potentially unique
network request.
