This prepares the support for OpenPGP v5 keys.  The new version 2 blob
format is needed for the longer fingerprints and we also use this
opportunity to prepare for storing the keygrip in the blob for faster
lookup by keygrip.  Right now this is not yet functional.

sm: Don't mark a cert as de-vs compliant if it leads to SHA-1 sigs.
* sm/keylist.c (print_compliance_flags): Also check the diges_also.
--

A certificate with algorithm sha1WithRSAEncryption can be de-vs
compliant (e.g. if the next in the chain used sha256WithRSAEncryption
to sign it and RSA is long enough) but flagging it as such is useless
because that certificate can't be used because it will create
signatures using the non-compliant SHA-1 algorithm.

Well, it could be used for encryption.  But also evaluating the
key-usage flags here would make it harder for the user to understand
why certain certificates are listed as de-vs compliant and others are
not.

sm: Fix certificate creation with key on card.
* sm/certreqgen.c (create_request): Fix for certmode.
--

When using an existing key from a card for certificate signing (in
contrast to the default of generating a CSR), the code tried to use
the same key for signing instead of the Signing-Key parameter.  It is
perfectly okay to use the regular signing path via gpg-agent for
certificate creation - only self-signed certificates with a key on the
card require the direct use of the card key (via "SCD PKSIGN").

Let me(wk) add this:

This bug was introduced with
Fixes-commit: 91056b1976bfb7b755e53b1302f4ede2b5cbc05d
right at the start of GnuPG 2.1 in July 2010.  Before that (in 2.0) we
used gpg-protect-tool which got it right.  We probably never noticed
this because gpgsm, and maybe other tools too, fix things up during
import.

--

This fixes a potential overflow if LFs are passed to the status
string functions.  This is actually not the case and would be wrong
because neither the truncating in libassuan or our escaping is not the
Right Thing.  In any case the functions need to be more robust and
comply to the promised interface.  Thus the code has been factored out
to a helper function and N has been bumped up correctly and checked in
all cases.

For some uses this changes the behaviour in the error case (i.e. CR or
LF passed): It will now always be C-escaped and not passed to
libassuan which would truncate the line at the first LF.

Originally the KBX code was written to allow standalone use.  However
this required lot of ugliness like separate memory allocators and
such.  It also precludes the use of some standard functions from
common due to their use of the common gnupg malloc functions.
Dropping all that makes things easier.  Minor disadvantages: the kbx
call done for gpg will now use gcry malloc fucntions and not the
standard malloc functions.  This might be a bit slower but removing
them even fixes a possible bug in keybox_tmp_names which is used in
gpg and uses gpg's xfree which is actually gcry_free.

sm: Allow explicit setting of the default --compliance=gnupg
* sm/gpgsm.c (main): Allow setting of the default compliance.
* tools/gpgconf-comp.c (gc_options_gpgsm): Add "compliance".

This is required so that we can use this option in in gpgconf.conf.

Use the gpgrt log functions if possible.
* common/logging.c: Do not build any code if we can use the gpgrt_log
functions.
(log_logv_with_prefix): Rename to log_logv_prefix and change order of
args so that this function matches its printf like counterpart
gpgrt_logv_prefix.  Change all callers.
(log_debug_with_string): Rename to log_debug_string. Change all
callers.
(log_printhex): Move first arg to end so that this function matches
its printf like counterpart gpgrt_log_printhex.  Change all callers.
* common/logging.h: Divert to gpgrt/libgpg-error if we can use the
gpgrt_log functions.
(bug_at): Add inline versions if we can use the gpgrt_log functions.
* configure.ac (GPGRT_ENABLE_LOG_MACROS): Add to AH_BOTTOM.
(mycflags): Add -Wno-format-zero-length.
--

This patch enables the use of the log function from libgpgrt (aka
libgpg-error).  Instead of checking a version number, we enable them
depending on macros set by recent gpg-error versions.  Eventually the
whole divert stuff can be removed.

The -Wno-format-zero-length is required because log_printhex can be
called with an empty format string.  Note that this is fully specified
standard C behaviour.

sm, w32: Fix initial keybox creation
* sm/keydb.c (maybe_create_keybox): Open new keybox in bin mode.

--
As the header contains a timestamp we will have the conversion
problems if the keybox is not opened in binary mode.

As described in my report T1644, it is possible that multiple
certificates exist with the same Distinguished Name and the same key.
In this case, verifying S/MIME signatures and other actions fail with
"certificate not found: Ambiguous name". For details see the bug
report.

To circumvent the problem, I am patching GnuPG since 2014 so that in
this case the newest of the ambiguous certificates is used.

This is not an ultimate solution of the problem: You should try every
certificate with the same DN until verification succeeds or until all
certificates fail, and if multiple certificates of a chain are
ambiguous you even have to check every combination. You may even
consider checking the keyUsage attributes of the ambiguous certificates
to reduce the number of combinations.

But in the existing case of the certificates in the German Research
Network (DFN) PKI where the newest one is the valid one and all
ambiguous certificates have the same keyUsage attributes, this patch
has proven to be sufficient over the last three years.

With every GnuPG update, I have adapted the patch, luckily I never
needed to change anything except line numbers.

This new option can be used to detect ROCA affected keys.  To scan an
entire keyring and print the affected fingerprints use this:

  gpg -k --with-key-screening --with-colons | gawk -F: \
       '$1~/pub|sub|sec|ssb|crt/ && $18~/\<6001\>/ {found=1;next};
        $1=="fpr" && found {print $10}; {found=0}'

The same works for gpgsm.  Note that we need gawk due to the "\<" in
the r.e.
