* scd/app.c (strcardtype): Support it.
(atr_to_cardtype): New.
(app_new_register): Try to get the cardtype from atr_to_cardtype.
* scd/app-piv.c (app_select_piv): Tweak for SCE7. Add general method
to construct a S/N from the Card UUID.

The test cards I have are rsa2048 with X.509 certificates. I don't
have the entire chain but loading the certificates work. For testing
I created an OpenPGP key from the keys and tested signing and
decryption.

* scd/app-common.h (struct card_ctx_s): Add maybe_check_aid flag.
* scd/command.c (cmd_apdu): Set it.

(maybe_switch_app): Do a re-select if this flag is set.
--
After the gpg-card tool has issued a Yubikey specific command the
current application is not anymore correctly selected. This then
results in all kind of errors. We detect this now and try to
re-select the last app.
* scd/app.c (app_auth): It's only APPTYPE_OPENPGP which supports
the challenge response interaction.
* scd/command.c (cmd_pkauth): It only wants if it works or not.

(readcert_by_cdf): Cache the ksba cert object instead of the binary
cert.
* scd/app.c (select_additional_application): Fix a log_debug call.
(scd_update_reader_status_file): Ditto.
--
This allows us to return only KEYPAIRINFO lines for keys we can
actually use.
* scd/app.c (app_dump_state): Also print the refcount.
(maybe_switch_app): Make sure the app exists on the card.
--
When switching the current card and the card does not support the same
apps as the former, we now reset the app to the first one.
Testcase is to use a standard OpenPGP card and a P15 card.

* scd/app.c (is_same_serialno): New.
(check_application_conflict): Use this.
(select_application): Ditto.
(app_switch_current_card): Ditto.
* scd/app-openpgp.c (check_keyidstr): Ignore the card version and also
compare case insensitive.
--
This is required because we change what we emit as serialno of OpenPGP
cards but existing keys still use the old form of the serial
number (i.e. with a firmware version).

This patch gets us back to a unique serial number for cards and
provides a stable serial number as printed for Yubikeys.
Because we use a slightly different serial number now for Yubikeys and
cards only supporting OpenPGP card we need to come up with another
change so that the version number of OpenPGP serial numbers are
ignored when comparing card serial numbers. This is so that existing
stub keys of gpg-agent will continue to work.

We need to use es_fopen on Windows to cope with non-ascii file names.
This is quite a large but fortunately straightforward change. At a
very few places we keep using stdio (for example due to the use of
popen).

apdu_get_slot() may only be used after the APP has been initialized.
Thus we need to pass teh slot here directly.

* scd/app.c (select_all_additional_applications_internal): Re-select
first app. Add arg 'ctrl'.
--
Usually keygrip based access to the Yubikey does a switching back and
forth and thus keeps the card and scdaemon's internal state in sync.
However, if we do only a listing scdaemon did not reselect the first
application (e.g. OpenPGP) after adding other applications (e.g. PIV)
and thus led to wrong info returned in a listing.

This has been tested with a D-Trust card featuring 3072 bit keys.
Note that non-repudiation key for a qualified signature does not yet
work because we do not yet support rsaPSS padding. Thus a gpgsm
--learn shows a couple of Bad Signature errors for this key.

The PIV pins are padded but we want to store the unpadded PIN. Thus

we the current test certificate was created for PIV.9C which requires
a verification for each use. More testing is required.

This option is currently only useful for Yubikeys and basically

SERIALNO --all
LEARN --force --multi
which will then print keypairinfo and other stuff for the OpenPGP and
PIV application of a Yubikey. Scute is going to use this to allow
using certificates from OpenPGP and PIV at the same time.
