indent: Fix spelling
--

These are non-substantive corrections for minor spelling mistakes
within the GnuPG codebase.

With something like this applied to the codebase, and a judiciously
tuned spellchecker integrated as part of a standard test suite, it
should be possible to keep a uniform orthography within the project.

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

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

scd: Fix Yubikey app switching problem
* 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.

* scd/app-p15.c (struct cdf_object_s): Use bit flags
(struct aodf_object_s): Ditto.  Add field 'fid'.
(struct prkdf_object_s): Ditto.  Add fields keygrip, keyalgo, and

(parse_certid): Allow a keygrip instead of a certid aka keyref.
(read_ef_aodf): Store the FID.
(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.

--

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

Code has has been tested by commenting the no_cache parameter because
we the current test certificate was created for PIV.9C which requires
a verification for each use.  More testing is required.
