agent: Allow arguments to "scd serialno" in restricted mode.
* agent/command.c (cmd_scd): Allow it.
--

This is important because Scute uses "SCD SERIALNO --all".

gpg: New export option "mode1003".
* agent/command.c (cmd_export_key): Add option --mode1003.
(command_has_option): Ditto.
* g10/build-packet.c (do_key): Implement mode 1003.
* g10/parse-packet.c (parse_key): Ditto.
* g10/options.h (EXPORT_MODE1003): New.o
* g10/call-agent.c (agent_export_key): Add arg mode1003.
* g10/export.c (parse_export_options): Add "mode1003"
(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: Avoid blanks in the ssh key's comment.
* 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.

With the global options we can now avoid that a user changes the

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.

agent: always use hexgrip when storing key password
--
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
crash seen in some libsecret implementations where a non-ascii keyid
isn't well handled.

(keyedit_menu): Implement.

--

The plumbing is done in two parts: the agent is modified to understand
a KEYTOTPM assuan command taking the key grip as an argument.  This
simply obtains the key s expression and calls the existing writeky
diversion to the tpm2daemon.  The daemon reponds with the TPM
conversion of the key and that key is then stored in the keyfile as a
shadowed-private-key with "tpm2-v1" type.

To effect the conversion, all the user does from gpg --edit-key is
select which private key they wish to move (or move the primary if no
key is selected) and type keytotpm.  The conversion to TPM form is
instantaneous and once converted, the actual key cannot be recovered,
meaning that if you want your gpg key to move to a new laptop you must
keep an unconverted backup copy in a safe location.

When you do a list command, all TPM keys show up as

     card-no: TPM-Protected

The key is stored encrypted to the TPM2 storage seed and since each
TPM has a unique seed, only the single TPM contained in your laptop
can now read the key.  This means you cannot simply copy the shadowed
key file over to a new laptop, you must copy over the backup copy and
then convert it to TPM form on the new laptop.

To decomission your laptop, execute a tssclear command which
regenerates the storage seed and effectively shreds all keys.  Note
when you have done this *every* TPM2 shadowed private key becomes
unreadable by any TPM and all are effectively destroyed.

---

A new shadow key type: "tpm2-v1" is introduced signalling that the
shadowed key is handled by the tpm2daemon.  A function to identify
this type is introduced and diversions to the tpm2daemon functions are
conditioned on this function for pkign and pkdecrypt where the same
diversions to scd are currently done.  The (info) field of the
shadowed key stores the actual TPM key.  The TPM key is encrypted so
only the physical TPM it was created on can read it (so no special
protection is required for the info filed), but if the (info) field
becomes corrupt or damaged, the key will be lost (unlike the token
case, where the key is actually moved inside the token).

Note, this commit adds handling for existing TPM format shadow keys,
but there is still no way to create them.

w32: Cleanup use of pid_t in call-daemon
* agent/call-daemon.c (struct wait_child_thread_parm_s) [W32]: Do not
use HANDLE for pid_t.
(wait_child_thread): Ditto.
--

Mingw has its own definition of pid_t as does libassuan.  We should use
this instead of using HANDLE.  Things are a bit complicated in
Windows, because Windows also has a pid_t but that is mostly useless;
in particular because you can't wait on a real pid but need a handle.

Our policy is to use VERY_STRONG for a long term public key but not

The GNU standards to demand that strings start with a lowercase
because that seems to be needed if it follows a prefix of for example
"gpg:".  I don't actually like this becuase we need different strings
in interactive and standard mode but the majory of strings in GnuPGare
written this way.  If a translation is necessary it can be done with
an en_GB or so locale.

agent: Print an error if gpg-protect reads the extended key format.
* agent/protect-tool.c (read_key): Detect simple extended key format.
--

This is a quick hack to get a useful error messages.  The real fix is
to replace the protect tool by a more useful new tool.

There is no need to read the list of options from the components
unless they convey a default value.  It is better to consult only the
list we have in gpgconf-comp.c to decide on whether an option should
be displayed.   Right, this might mess up thing if a newer gpgconf
version is used with an older component, but we already print warnings
in this case and in general we do not want to support this anymore -
the times of gpg 1.4. and 2.0 are long over now.

This looks better and is also required for further simplifications of
gpgconf.

gpgconf: Support reading global options (part 2).
* tools/gpgconf-comp.c: Remove all regular option descriptions.  They
are now read in from the component.  Also remove a few meanwhile
obsolete options.
* agent/gpg-agent.c: Add option description which were only set in
gpgconf-comp.c.
* dirmngr/dirmngr.c: Ditto.
* scd/scdaemon.c: Ditto.
* sm/gpgsm.c: Ditto.
* g10/gpg.c: Ditto.
--

This second part removes all regular option descriptions because they
can be read from the components.  A few were missing in the components
and thus moved to there.
