scd: Fix flushing of CA-FPR data objects
* scd/app-openpgp.c (do_setattr): Add new table item to flush a
different tag.

--

For whatever reasons the OpenPGP card reads the 3 CA fingerprints from
one object but sets them individually using 3 different tags.  The
cache flushing was not prepared for this and so a changed CA
fingerprint showed only up after a card reset.  This patch fixes it.

NIIBE Yutaka fec75a3868 scd: Support PASSWD --clear for OpenPGP card.
* 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).

gpg: Stop early when trying to create a primary Elgamal key.
* 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.

card-tool: Add skeleton for new tool
* tools/gpg-card-tool.c: New.
* tools/gpg-card-tool-w32info.rc: New.
* 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.

wks: Do not use compression for the encrypted data.
* 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.
