* scd/app-openpgp.c (do_change_pin): Implement handling
APP_CHANGE_FLAG_CLEAR.
--
It is specified in the specification version 3.1 or later. Some
version 2 cards (including Gnuk) support this feature. Any version 1
card has no support for this feature.
For CHVNO = 1, it clears for both of 81 and 82; That is, user's key
usages for signing and others (decryption and auth).
For CHVNO = 3, it clears for 83, admin key.
For CHVNO = 2, it clears 82; That is, user's key usages
others (decryption and auth).

* g10/misc.c (openpgp_pk_test_algo2): Add extra check.
--
The problem is that --key-gen --batch with a parameter file didn't
detect that Elgamal is not capable of signing and so an error was only
triggered at the time the self-signature was created. See the code
comment for details.

* tools/Makefile.am: Add new tool.
--
To support more cards than the OpenPGP card it is useful to have a
separate tool. It will have have the "gpg --card-edit" style
interactive interface as well as direct command line options for all
commands. In a first step the OpenPGP card will be supported, to
allow its use as an alternative to the gpg command, and the
forthcoming PIV card support.
The tool can be though as a direct interface to scdaemon.

(gnupg_status_printf): New.

Some of the extra tools take a --status-fd option to print certain
status messages. A generic printf style print function thus makes
sense.

Right now this allows the use of the authentication key (9A) for SSH
authentication. More support will follow soon.
Tested with Yubikey-5.
* scd/apdu.c (apdu_send_direct): New arg R_SW.

arg.
--
iso7816_general_authenticate will be used for the PIV card support.
The new arg to iso7816_apdu_direct and apdu_send_direct allows to get
the raw status word back without the need to handle an output buffer.

* agent/command-ssh.c (struct ssh_key_type_spec): Add field
alt_curve_name.
(ssh_key_types): Add some alternate curve names.
(ssh_identifier_from_curve_name): Lookup also bey alternative names
and return the canonical name.
(ssh_key_to_blob): Simplify the ECDSA case by using gcry_pk_get_curve
instead of the explicit mapping.
(ssh_receive_key): Likewise. Use ssh_identifier_from_curve_name to
validate the curve name. Remove the reverse mapping because since
GnuPG-2.2 Libgcrypt 1.7 is required.
(ssh_handler_request_identities): Log an error message.
--
This change will make it easier to support other curves, in particular
those from tokens. Libgcrypt has a large list of alias names which we
now use to to make the mapping more flexible.

* scd/command.c (cmd_readkey): Reformat for advanced mode.

The --advanced option used to work only if the driver supported that

* tools/gpg-wks-client.c (encrypt_response): Add arg -z0.
* tools/gpg-wks-server.c (encrypt_stream): Ditto.
--
If for example a server was built without the development packages of
the compression libraries installed, the server will not be able to
decrypt a request. In theory this can't happen due to the preference
system but it is just to easy to create the server's key using a
different version of gpg and then use gpg-wks-server built
differently.
For the short messages we exchange compression is not really required
and thus we better do without to make the system more robust.

The reading of uninitialized data is harmless but we better fix it to
make valgrind happy. More serious was that we always passed
MAX_FINGERPRINT_LEN but we will need to support 20 and 32 octet
fingerprints and MAX_FINGERPRINT_LEN would be too large for a v4.

What we want to do here is to serialize the call of

that a call of select_application was blocked internally,
and then another call of select_application entered.
We can have a dedicated lock for call of select_application,
but it is easier to re-use APP_LIST_LOCK.
