This basically works now but for my test card I need to pass

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.

(keygripstr_from_prkdf): Rename to ...
(keygrip_from_prkdf): this.  Remove arg r_gripstr and implement cache.
Change callers to directly use the values from the object.  Also store
the algo and length of the key ion the object.
(keyref_from_keyinfo): New. Factored out code.
(do_sign): Support SHA-256 and >2048 bit RSA keys.
(do_with_keygrip): New.
(app_select_p15): Register new function.

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.

This removes almost all log_debug calls and uses opt.verbose and
log_info to show card information.  Also avoid too long and thus
harder to read lines.

The card under test is a "Test-Signaturkarte D-TRUST Card 3.1" for a
mere 49 Euro and no specs available.  D-Trust is a branch of the
German Bundesdruckerei.  Compare that to Telesec and Yubikey who have
always been nice enough to send bunches of sample cards without a need
to wade through lots of forms and not even asking for money.  Guess
which cards I prefer.
