Some information from parsing the card are often very helpful.
However, the card_io triggered APDU dumps are in most cases too heavy.
Thus this new debug flag.
* scd/app-openpgp.c (do_auth): Allow larger data for RSA-4096.
--
OpenPGPcard specification says that it will be rejected by the card
when it's larger. We have been the check on host side too, but it was
written when it only had a support for RSA-2048.

Due to an assignment out of bounds this might lead to a crash if there

--
There was an obvious bug in that the pcsc.count could go below zero
and thus there was no chance to get the context release. Releasing
and recreating the context is at least under Windows important to get
rit of the PCSC_E_SERVICE_STOPPED.
Also removes a potential problem in holding the reader_table_lock
between calls to apdu_dev_list_start apdu_dev_list_finish. There is
no need for this. Instead we bump the pcsc.count.
The reader_table_lock strategy should be reviewed; we may be able to
remove it.

The do not cache property of 6E was introduced so that we can change
for example key attributes without getting into with the cache.
However, for initial reading the cache makes a lot of sense and thus we
now use this hack to only temporary cache. A better strategy would be
to clear the cache when we change card data but that is more error
prone.

There used to be a possible support of Ed25519 with ECDSA, (instead of
EdDSA). To distinguish key for Ed25519 for EdDSA, we use the
flag: (flags eddsa). Ed448 has no support for ECDSA and defaults to
EdDSA even if no such flag.

It appears that SP-800-73-x is not too clear about the format of these
objects. Many current cards (such as the Yubikey 5 series) apparently
have only the PIX in DO 0x4F and only the RID in object 0x79/0x4F.
However, other cards as well as the PivApplet Javacard applet have the
full AID in 0x4F (which actually seems closer to what the standard
says). PivApplet also has the full AID in 0x79/0x4F, but this is
probably incorrect. (Here is a long discussion of the matter from an
OpenSC author:

This features allows to mark keys to be used for OpenPGP. This is
done by putting additional extended key infos into the certificate
stored on the cards. Only if any such extended key usage is detected
for a stored certificate this new mode chimes in.
This feature gives the card issuer a high flexibility on how to make
sure certain keys are used with OpenPGP.
