On Windows it is easier to set the registry key than to use an envvar.

Use

  GNUPG_ASSUME_COMPLIANCE=de-vs gpg --compliance=de-vs ....

for testing.  This returns 2023 instead of 23 to indicate the
non-approval state.

common: Fix test for the assumed compliance.
* common/compliance.c (gnupg_status_compliance_flag): Fix test.
--

In general the cache is used to query this flag but in this function
it is used directly and we need to adjust the test.

Thanks to Ingo for reporting this.

Implement GNUPG_ASSUME_COMPLIANCE envvar for testing
* common/compliance.c (assumed_de_vs_compliance): New.
(get_compliance_cache): Check envvar and fake compliance.
(gnupg_status_compliance_flag): Return 2023 for de-vs if in faked
mode.
* g10/gpg.c (gpgconf_list): For compliance_de_vs return 23 or 2023.
--

The user visible changes are that

   GNUPG_ASSUME_COMPLIANCE=de-vs gpgconf --list-options gpg \
     | awk -F: '$1=="compliance_de_vs" {print $8}'

returns 2023 if "compliance de-vs" is found in gpg.conf.  If
eventually the software is arpproved the returned value will be 23 and
not 1 as it was before.  Consumers should check whether they see value
of true (Kleopatra does this right now) and also check whether the
value is > 2000 and in this case print a beta/non-approved warning.

The envvar is currently used to assume that the underlying libgcrypt
is compliant and approved.  This is not yet the case but eventually
libgcrypt will announce this itself and from then on the envvar is not
anymore required for testing.

These are non-substantive corrections for minor spelling mistakes

With something like this applied to the codebase, and a judiciously

It does not make anymore sense to allow building with older Libgcrypt
versions.  After all PQ key support is a major feature and for this we
need Libgcrypt.

--

Test by creating an ed25519 key and using

 gpg --quick-add-key --batch --passphrase ""  <fingerprint> <algo>

to create several subkeys.  Tested with ALGOs:

  kyber768
  kyber1024
  ky768_cv25519
  ky768_bp256
  kyber768_nistp256
  ky1024_cv448

All curves capable of encryption should work.

gpg: Initial support for generating Kyber subkeys.
* common/openpgpdefs.h (PUBKEY_ALGO_KY768_25519): Remove.
(PUBKEY_ALGO_KY1024_448): Remove.
(PUBKEY_ALGO_KYBER): New.  Use them everywhere instead of the removed.

* g10/build-packet.c (gpg_mpi_write_nohdr): Rename to

(do_key): Support Kyber keys using the revised format.
* g10/gpg.h (MAX_EXTERN_KEYPARM_BITS): New.
* g10/parse-packet.c (read_octet_string): Add arg nbytes so support
reading with a length prefix.  Adjust callers.
(parse_key): Parse Kyber public keys.
* g10/misc.c (pubkey_get_npkey): Support Kyber.

* g10/keyid.c (pubkey_string): Support dual algorithms.
(do_hash_public_key): Support Kyber.
(nbits_from_pk): Ditto.
(keygrip_from_pk): Return the Kyber part for the ECC+Kyber dual algo.

* g10/keygen.c (struct common_gen_cb_parm_s): Add genkey_result2.
Note that this callback is not yet used.
(ecckey_from_sexp): Add optional arg sexp2 and use it for Kyber.
Change callers.
(ecckey_from_sexp): Do not leak LIST in case of an error.
(common_gen): Add arg keyparms2, change callers, and support Kyber.
(gen_kyber): New.
(get_keysize_range): Support Kyber.
(fixup_keysize): Simplify and support Kyber.
(do_create): Handle Kyber.
(parse_key_parameter_part): Remove algo strings "ky768" and "ky1024"
and add a generic "kyber" with default parameters.
--

This uses a revised format which is more aligned with the usual
OpenPGP structure.  A lot of things are still missing.  For example
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

and then running

  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.

For dual algorithms (PQC) we need shorter versions of brainpool to
avoid names which otherwise might be capped when printed.

This is a unification of the gpgconf.ctl mechanism.  For backward
compatibility we need to keep the empty (or actually only comments)
method as used formerly under Windows.  Iff one really wants a
portable application the new portable keyword should be used, though.

Noet that the Windows portable stuff has not been tested for quite
some time.
