(rsa_write_key, ecc_writekey): Force string the fingerprint.
--
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

* agent/command.c (cmd_preset_passphrase): Add option.
* agent/preset-passphrase.c (oRestricted): New.
(opts): Add option --restricted.
(main): Set option.
(preset_passphrase): Use option.
--
We use a different cache for connections from the extra-socket.
However, with gpg-preset-passphrase is only able to preset a
passphrase into the regular cache. Further, a restricted connection
may not use PRESET_PASSPHRASE. To solve this we add an new option to
preset the passphrase into the "restricted" cache. For the
gpg-preset-passphrase tool we also add the option --restricted.
Note that this does not yet work with gpg-preset-passphrase --forget.
* agent/agent.h (opt): Remove enable_extended_key_format.
* agent/gpg-agent.c (enum cmd_and_opt_values): Turn
oDisableExtendedKeyFormat and oEnableExtendedKeyFormat into dummy

* agent/protect.c (do_encryption): Remove arg use_ocb and

* agent/findkey.c (agent_write_private_key): Simplify due to the

The first patch fixes a likely merge error. The second is about the
actual return code: If we have no smardcard but simply try to decrypt
with the current smartcard we should return the originla error code.

We now first return the keys from active cards, followed by keys
listed in sshcontrol, finally from those with the "Use-for-ssh" key
attribute. Keys from active cards are returned sorted by their S/N.
Keys from sshcontrol are returned in the order they are given in that
file. Use-for-ssh keys are ordered by the value assigned to that key
attribute. The values for the latter are clamped at 99999.
* common/name-value.c (nvc_get_boolean): Rewrite.

The function may now return a positive or negative number instead of
just 1 for true. All callers were already prepared for this.

(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.
* agent/command-ssh.c (card_key_available): Replace blanks.
--
For managing the authorized_key file of ssh it is convenient if the
comment does not have any spaces. Thus we now return
cardno:FFFE_50FF3D01
instead of
cardno:FFFE 50FF3D01
Note that gpg --export-ssh-key uses the keyid as comment because it
does not known the S/N of the card. Gpg-agent however does not know
about OpenPGP and uses the s/n.

format. Handle the case when key is in non-extended format.

--
With the global options we can now avoid that a user changes the
Root-CA trust by editing the trustlist.txt. However, to implement
this we need a new option so that we don't need to rely on some magic
like --no-allow-mark-trusted has been put into a force section.
The second option makes system administration easier as it allows to
keep the trustlist in a non-distributed file.

--
Actually we could handles this different by not putting a comment tag
into the s-expression, however this requires more code and at other
places we already return "(none)" instead of an empty comment.
The second fix is more or less a cosmetic thing to get better error
messages in case the underlying read system call returns an error.

The current code uses the binary ctrl->keygrip, but all the passphrase
storage engines expect this to be a string, so convert the binary
keygrip to a hex one before passing it in as the keyid. This fixes a

isn't well handled.

Requirements for a passphrase to protect a private key and for a

encryption.
