gpg: Fix writing ECDH keys to OpenPGP smartcards.

compute the fingerprint.

writing the fingerprint back to the card if not set.
(read_public_key): Also add arg meta_update.

(rsa_write_key, ecc_writekey): Force string the fingerprint.
--

The problem showed up because in 2.4 we changed the standard ECDH
parameter some years ago.  Now when trying to write an ECDH key
created by 2.2 with 2.4 to an openpgp card, scdaemon computes a wrong
fingerprint and thus gpg was not able to find the key again by
fingerprint.

The patch also avoids updating the stored fingerprint in certain
situations.

This fix is somewhat related to

gpg: New command "openpgp" for --card-edit.
* g10/card-util.c (current_card_status): Print a hint for fishy

(enum cmdids): Add cmdOPENPGP.
(cmds): Add "openpgp".

--

If a Yubikey has been used in PIV mode the initial listing does not
look correct.  Although we explicitly switch to the OpenPGP app when
needed, we don't want to do this in listing mode.  Instead we offer a
new command "openpgp" to force the openpgp mode.  The ultimate goal
will be to enhance the gpg-card tool to completely take over the
--card-edit features.  But we are not yet there.

* g10/call-agent.c (agent_scd_switchapp): New.
* g10/card-util.c (get_info_for_key_operation): Call it.
--

It may happen that the active card was last used for PIV and in that
case certain commands will fail because they assume the OpenPGP app.
Fortunately we have a pretty central place to assure that the right
app has been selected.

The bug can be easily noticed on Windows.

After the gpg-card tool has issued a Yubikey specific command the
current application is not anymore correctly selected.  This then
results in all kind of errors.  We detect this now and try to
re-select the last app.

We use a different cache for connections from the extra-socket.

passphrase into the regular cache.  Further, a restricted connection
may not use PRESET_PASSPHRASE.  To solve this we add an new option to
preset the passphrase into the "restricted" cache.  For the
gpg-preset-passphrase tool we also add the option --restricted.

gpgsm: Strip trailing zeroes from detached signatures.
* common/ksba-io-support.c: Include tlv.h
(struct reader_cb_parm_s): Add new fields.
(starts_with_sequence): New.
(simple_reader_cb): Handle stripping.
* common/ksba-io-support.h (GNUPG_KSBA_IO_STRIP): New.
(gnupg_ksba_create_reader): Handle the new flag.

Note that this works only if --assume-binary is given.  The use case
for the feature is PDF signature checking where the PDF specs require
that the detached signature is padded with zeroes.

This makes use of a new encryption flag:

  The "restricted encryption key" (2nd,0x04) does not take part in any
  automatic selection of encryption keys.  It is only found on a
  subkey signature (type 0x18), one that refers to the key the flag
  applies to.

Followup patches will add encryption support and a --quick command.
