gpg: Improve decryption diagnostic for an ADSK key.
* g10/keydb.h (GET_PUBKEYBLOCK_FLAG_ADSK): New constant.
* g10/packet.h (PUBKEY_USAGE_XENC_MASK): New constant.
* g10/pubkey-enc.c (get_session_key): Consider an ADSK also as "marked
for encryption use".
(get_it): Print a note if an ADSK key was used.  Use the new
get_pubkeyblock flag.
* g10/getkey.c (struct getkey_ctx_s): Add field allow_adsk.
(get_pubkeyblock): Factor all code out to ...
(get_pubkeyblock_ext): new.
(finish_lookup): Add new arg allow_adsk and make use of it.
--

This patch solves two purposes:
- We write a note that the ADSK key was used for decryption
- We avoid running into a
  "oops: public key not found for preference check\n"
  due to ADSK keys.  The error is mostly harmless but lets gpg return
  with an exit code of 2.

gpg: New debug flag "keydb".

* g10/keyring.c: Ditto.

Using "lookup" also for key search debugging was not a good idea.
This uses a separate flag for the latter.

gpg: Do not bail out on secret keys with an unknown algo

If the local store has private keys with an algorithm not supported by
thi version of gpg, gpg used to bail out.  Thus decryption of proper
messages was not possible.  This fix skips such secret keys.

The old LDAP mechanism to locate a server via SRV records has long
been gone (since 2014) due to the dropping of the keyserver helpers.
The new purpose better reflects reality and can be used in
environments where keys are provided by an in-house LDAP server.

indent: Fix spelling
--

These are non-substantive corrections for minor spelling mistakes
within the GnuPG codebase.

With something like this applied to the codebase, and a judiciously
tuned spellchecker integrated as part of a standard test suite, it
should be possible to keep a uniform orthography within the project.

gpg: Add arg session_algo to pk_decrypt.
* common/kem.c: Move constants to the top.  Add some documentation.
* g10/pkglue.c (pk_encrypt): Add arguments session_key and factor code
out to ...
(do_encrypt_rsa_elg): here,
(do_encrypt_ecdh): and here,
(do_encrypt_kem): and here.
* g10/encrypt.c (write_pubkey_enc): Call with session key algorithm.
--

This makes it easier to review the code.

gpg: Prepare to use the fingerprint as fixed-info for Kyber.
* g10/pubkey-enc.c (get_it): Use algo and fingerprint for the
fixed-info.  Keep a testing mode.
* g10/options.h (COMPAT_T7014_OLD): New.
* g10/gpg.c (compatibility_flags): Add "t71014-old" flag.

gpg: Simplify the pk_encrypt function interface.
* g10/pkglue.c (pk_encrypt): Remove superfluous arguments and reanem
variable rc to err.
* g10/encrypt.c (write_pubkey_enc): Adjust for this change.
--

We used to pass PK as well as information which could be taken
directly from PK.  Using ERR instead of RC is just for more uniform
naming of variables.

gpg: Changed internal data format for Kyber.
* g10/packet.h (PKT_pubkey_enc): Add field seskey_algo.
(struct pubkey_enc_list): Ditto.
* g10/misc.c (pubkey_get_nenc): Change value for Kyber from 4 to 3.
* g10/parse-packet.c (parse_pubkeyenc): Store the Kyber algo in the
new field and adjust data.  Do not store the length byte in data[2].
* g10/build-packet.c (do_pubkey_enc): Take the session algo for Kyber
from the new field.
* g10/encrypt.c (write_pubkey_enc): Ses the seskey_algo.
* g10/mainproc.c (proc_pubkey_enc): Copy it.
* g10/pubkey-enc.c (get_it): Support Kyber decryption.

* g10/seskey.c (encode_session_key): Handle Kyber different from ECDH.

Having always the single byte in the packet data than to store and
retrieve it from an MPI is much easier.  Thus this patch changes the
original internal format.  With this chnages decryption of the slighly
modified test data works now. See the bug tracker for test data.

gpg: Make Kyber creation more flexible.
* common/openpgp-oid.c (openpgp_is_curve_supported): Allow the
abbreviated curve name.
* g10/pkglue.c (pk_encrypt): Add debug output.
* g10/seskey.c (encode_session_key): Handle Kyber session key like
ECDH.  This is just a stub.
* g10/keygen.c (ecckey_from_sexp): Use the modern OID for cv25519.
(parse_key_parameter_part): Allow more Kyber variants.
--

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.
