Using _open instead of CreateFile give the same number of file events
but increased the time slight by one second for the measured buffer

The problem showed up because in 2.4 we changed the standard ECDH
parameter some years ago. Now when trying to write an ECDH key
created by 2.2 with 2.4 to an openpgp card, scdaemon computes a wrong
fingerprint and thus gpg was not able to find the key again by
fingerprint.
The patch also avoids updating the stored fingerprint in certain
situations.
This fix is somewhat related to

* g10/card-util.c (current_card_status): Print a hint for fishy

(enum cmdids): Add cmdOPENPGP.
(cmds): Add "openpgp".
(card_edit): Implement that command.
--
If a Yubikey has been used in PIV mode the initial listing does not
look correct. Although we explicitly switch to the OpenPGP app when
needed, we don't want to do this in listing mode. Instead we offer a
new command "openpgp" to force the openpgp mode. The ultimate goal
will be to enhance the gpg-card tool to completely take over the
--card-edit features. But we are not yet there.

It may happen that the active card was last used for PIV and in that
case certain commands will fail because they assume the OpenPGP app.
Fortunately we have a pretty central place to assure that the right
app has been selected.
The bug can be easily noticed on Windows.

This used to work using the gpg-agent: learn we called at "save" time.
However, the recent change inhibited the creation of a shadow key by
learn if a regular key still exists. Now we do an explicit delete key
at save time. This syncs the behaviour with the description of the
man page.

This makes use of a new encryption flag:
The "restricted encryption key" (2nd,0x04) does not take part in any
automatic selection of encryption keys. It is only found on a
subkey signature (type 0x18), one that refers to the key the flag
applies to.
Followup patches will add encryption support and a --quick command.
GnuPG-bug-id: 6395
* g10/gpg.c (main): Replace setmode by es_set_binary and use only when
needed.
--
It is better to use our es_set_binary than to use a Windows specific
method which still worked but is fragile because estream might be
changed. We now set binary only when needed. Note that it does not
harm to call es_set_binary more often than needed.

* g10/keylist.c (list_signature_print): Early return for weak key

(list_keyblock_print): Simplify and always set self-sig node flag.
--
This patch avoid the printing of often hundreds of "Invalid digest
algorithm" notices during key signature listings if those key
signatures were done with SHA1. The new option can be used to revert
the behaviour.
We now also print "[self-signature]" with --check-sigs or --list-sigs
instead of the primary user id. This makes such listing easier to read.
* g10/gpg.c (parse_list_options): Set value for show-sig-subpackets.

--
The introduction of --override-compliance-check actually hid the real
cause for the signature verification problem in de-vs mode for the
Ed25519 key. The real fix is to handle the EdDSA algorithm in
gnupg_pk_is_allowed.

We don't use the system's printf but the one implemented by
us (gpgrt's estream-printf) thus the PRIu64 may or may not be correct.
We can't do much about the -Wformat errors due to our different
implementation.
* agent/command.c (cmd_export_key): Add option --mode1003.
(command_has_option): Ditto.
* g10/build-packet.c (do_key): Implement mode 1003.

(secret_key_to_mode1003): New.
(receive_seckey_from_agent): Add arg mode1003.
(do_export_one_keyblock): Pass option down.
--
This option allows to export a secret key in GnuPG's native format.
Thus no re-encryption is required and further the public key parameters
are also authenticated if a protection passphrase has been used.
Note that --import is not yet able to handle this new mode. Although
old version of GnuPG will bail out with "invalid packet" if a mode1003
exported secret key is seen.
* g10/export.c (receive_seckey_from_agent): Add arg r_key.
(do_export_one_keyblock): Pass NULL for new arg.
(receive_raw_seckey_from_agent): Remove.

Without this fix require-compliance would fail if no --status-fd was

* g10/import.c (impex_filter_getval): Add scope support and new
property names "key-size", "algostr", "origin", "lastupd", and "url".
--
This option is pretty useful to select keys based on their properties.
The scope thing can be sued to limit a selection to just the primary
key or to subkeys. For example:
gpg -k --list-filter 'select=revoked-f && sub/algostr=ed25519'
Lists all non-revoked keys with an ed25519 (signing)-subkey.
* g10/gpg.c (aQuickUpdatePref): New.
(opts): Add --quick-update-pref.
(main): Implement.
* g10/keyedit.c (keyedit_quick_update_pref): New.
(menu_set_preferences): Add arg 'unattended' and adjust caller.
--
This new quick command is in particular useful to update existing keys
so that they can be used with OCB mode.
* g10/armor.c (is_armored): Add PKT_ENCRYPTED_AEAD.
--
With this fix it is now possible to feed a vanilla packet of type 20
without first forcing gpg to assume binary mode.
* g10/gpg.c (oRFC4880bis): Remove.
(opts): Make --rfc4880bis a Noop.
(compliance_options): Make rfc4880bis to gnupg.
(set_compliance_option): Remove rfc4880bis stuff.
(main): Ditto. Note that this now activates the --mimemode option.
* g10/keygen.c (keygen_set_std_prefs): Remove rfc4880bis protection.
(keygen_upd_std_prefs): Always announce support for v5 keys.
(read_parameter_file): Activate the v4 and v5 keywords.

* g10/gpg.c (opts): New option--force-ocb as alias for force-aead.
Turn --aead-algo and --personal-aead-preferences into dummy options.
(build_list_md_test_algo, build_list_aead_algo_name): Remove.
(my_strusage): Remove output of AEAD algos.
(main): Remove code from the --aead options.
* g10/encrypt.c (encrypt_seskey): Make file local.
(use_aead): Remove requirement for rfc4880bis. Always return
AEAD_ALGO_OCB.
* g10/main.h (DEFAULT_AEAD_ALGO): Removed unused macro.
* g10/misc.c (default_aead_algo): Remove.
* g10/pkclist.c (select_aead_from_pklist): Return AEAD_ALGO_OCB or 0.
(select_algo_from_prefs): Remove personal AEAD algo setting.
* g10/keygen.c (keygen_set_std_prefs): Remove AEAD preference option
parsing.
* g10/options.h (opt): Remove def_aead_algo and personal_aead_prefs.
--
Due to the meanwhile expired patent on OCB there is no more reason for
using EAX. Thus we forcefully use OCB if the AEAD feature flag is set
on a key.
* g10/gpg.c (oCompatibilityFlags): New.
(opts): Add option.
(compatibility_flags): New list.
(main): Set flags and print help.
* g10/options.h (opt): Add field compatibility_flags.
--
No flags are yet defined but it is good to have the framework.
* g10/kbnode.c (new_kbnode2): New.
* g10/import.c (delete_inv_parts): New arg r_otherrevsigs to store
misplaced revocations.
(import_revoke_cert): Allow to pass an entire list.
(import_one): Import revocations found by delete_inv_parts.
--
It might be useful to distribute revocations of old keys along with
new keys. This is in particicualrr useful for WKD stored keys. This
patch allows to put unrelated standalone revocations into a key. For
example they can simply appended to a keyblock. Right now it is a bit
inaesthetic to see diagnostics about misplaced or bad revocation
signatures.
* g10/ecdh.c (derive_kek): Use GCRY_KDF_ONESTEP_KDF.
--
This change is not yet enabled. We will be able to use the code when
we update NEED_LIBGCRYPT_VERSION to 1.11.0. Before the update, gpg
compiled with libgcrypt 1.11.0 can't work with older libgcrypt
runtime.

Before 8402815d, original code was with iobuf_open_fd_or_name, which
used gnupg_fd_t for the file descriptor (FD2INT was relevant at that
time). After the change, because it's not gnupg_fd_t but int, use of
FD2INT is irrelevant.
