This allows to get information about the keys from the card.  However
the do_readkey still requires a fallback to readcert.  This does not
work because there are no certificates yet on the card.  The fix is to
fully implement do_readkey.

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.

For readers with interrupt transfer support, it is only intr_cb which

The function ccid_slot_status can also detect a communication error,
which causes apdu_close_reader (but not setting ->powered_off).

--

The "no_lc" hack lets PC/SC-lite send the ESC command for SPR532
internally, for pcsc_pinpad_verify.  However, PC/SC-lite doesn't do
that for pcsc_pinpad_modify, unfortunately.  Besides, I'm not sure
this hack works on Windows, which has different implementation of
PC/SC service.

It's better to send the ESC command by the driver explicitly, at the
initialization.  Sending the ESC command results PCSC_E_NOT_TRANSACTED
error when a card is not active (that is the case, usually).  We
ignore this error.

This can be used with gpg-card to write the 3 extra certificates of a
Telesec TCOS Signature Card v2.  The card with the qualified signature
is distributed with the keys for encryption and advanced signatures
but without the certificates.  The certificates can be downloaded from
the website after an mail confirmation.  Unpacked the downloaded
zipfile has these certificates:

  auth_zert.crt
  sig_zert.crt
  enc_zert.crt

Using gpg-card issue these commands:

 writecert NKS-NKS3.4531 <sig_zert.crt
 writecert NKS-NKS3.45B1 <enc_zert.crt
 writecert NKS-NKS3.4571 <auth_zert.crt

Don't mix that up, tight now there is no checking that the
certificates match the public key.  I also need to write another patch
to actually implement signing and encryption with these nistp256
certificates.

Usually keygrip based access to the Yubikey does a switching back and

application (e.g. OpenPGP) after adding other applications (e.g. PIV)

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.

(do_sign): Do not cache the PIN here.
--

Note that some of the changes are required because we can't rely that
the PIN is always cached in secure memory.  Thus it is better to do an
explicit wipe.

Testing the PIN cache can currently only be done my modifying the
code to do a verification for each operation.  Only some basic testing
has been done.  Clearing the PIN cache is also not fully
implemented.  With the forthcoming changes to app-piv we should be
enter able to test the PIN cache.

Missing stuff:
 - The agent should be able to selectively clear the cache on a per
   slot base.
 - We should replace AESWRAP by OCB.

This change does away with encrypting and decrypting the cached PIN in
the agent.  There is no need for this we can simply cache the
cryptogram and let scdaemon decrypt after retrieving it from the
agent.  This way we do not need to share a key between gpg-agent and
scdaemon and further the cached content is invalid after the scdaemon
process has been replaced.

Better safe than sorry.

We should also review the card reference counting to see whether we
better ref the returned card object already here.

This change will allow us to easier integrate an app swithcing logic.
The change should have no user visible effect.  The error checking we
do now with the card locked will rarely be asserted.  It is the
correct thing to do anyway.

In another patch we will need apptype_t in the ctrl object and thus we
need to reorganize things a bit now.  Given that most files need
app-common anyway it makes sense to always include it.

Using strcmp is lame and we can't use a switch to let the compiler
complain about missed cases.

Although quite large, this is a straightforward change to separate
card/token related data from card application related data.  Before
this change there was a one-to-one relation between card and
application and no way to represent several applications on a card.
The new data structure will allow for such a representation.

This is better in case we need to debug stuff.  There is a real change
however: We now lock and unlock the app before changing the reference
count.

The whole app locking business should be reviewed because we pass
pointers along without immediately bumping the refcount.

The only real chnage is the case for a too small buffer.  That should
in general never happen but if so we now return an error instead of
success.

There is no bug report regarding this and it would be very unlikely
