scd:openpgp: Fix PIN pin2hash_if_kdf.
* scd/app-openpgp.c (pin2hash_if_kdf): DEK had been changed to pointer
to allocated memory, so, we need to use DEKLEN for the length.

scd:openpgp: Allow PIN length of 6 also with a reset code.
* scd/app-openpgp.c (do_change_pin): Fix PIN length check.  Add "R"
flag to the reset code prompt.
--

When using the reset code it was not possible to set a PIN of length
6.  The "R" flags fixes a funny prompt.

scd:openpgp: Restructure the pin2hash_id_kdf function.
* scd/app-openpgp.c (wipe_and_free_string, wipe_and_free): Enable
functions.
(pin2hash_if_kdf): Change interface.  The input PIN is not anymore
changed.  Further there are no more assumptions about the length of
the provided buffer.

Note that this a part of the patch
63bda3aad8 which we used in 2.4 to
implement a PIN cache.  For easier backporting we need to add this
here.

scd:openpgp: Print a diagnostic for the use of default ECDH params.
* scd/app-openpgp.c (ecc_writekey): Remove the useless check and print
a diagnostic if the default params are used.
--

Note that here in 2.2 we use different default ECDH parameters than in
2.4 (AES192 instead of AES256 for 384 bit curves).

scd:openpgp: Use a special compare for the serialno.
* scd/app-openpgp.c (check_keyidstr): Ignore the card version and also
compare case insensitive.
(do_learn_status): Add mssing error handling.
--

This is required because we changed 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 is so that existing stub
keys of gpg-agent will continue to work.

--

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.

* scd/app-openpgp.c (struct app_local_s): Add new flag.
(get_cached_data): Force chace use if flag is set.
(app_select_openpgp): Avoid reading DO 6E multiple times.
--

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.
