--
Decryption using a card never worked in gpg 2.1 because the
information whether the pkcs#1 padding needs to be removed was not
available. Gpg < 2.1 too this info from the secret sub key but that
has gone in 2.1.

With the gpg-agent taking care of the secret keys, the user needs to
migrate existing keys from secring.gpg to the agent. This and also
the standard import of secret keys required the user to unprotect the
secret keys first, so that gpg-agent was able to re-protected them
using its own scheme. With many secret keys this is quite some
usability hurdle. In particular if a passphrase is not instantly
available.
To make this migration smoother, this patch implements an unattended
key import/migration which delays the conversion to the gpg-agent
format until the key is actually used. For example:
gpg2 --batch --import mysecretkey.gpg
works without any user interaction due to the use of --batch. Now if
a key is used (e.g. "gpg2 -su USERID_FROM_MYSECRETKEY foo"), gpg-agent
has to ask for the passphrase anyway, converts the key from the
openpgp format to the internal format, signs, re-encrypts the key and
tries to store it in the gpg-agent format to the disk. The next time,
the internal format of the key is used.
This patch has only been tested with the old demo keys, more tests
with other protection formats and no protection are needed.

* agent/command.c (cmd_import_key): Pass 0 instead of KEYLEN to
gcry_sexp_canon_len.
--
We used to pass KEYLEN to the gcry_sexp_canon_len for no good reason:
convert_from_openpgp is guaranteed to return a valid canonical
S-expression and KEYLEN would thus act only as an upper limit. This
is not a problem because usually the original input key is longer than
the returned unprotected key. A future patch may change this
assertion and thus we better fix this bug now.

For ECDSA and ECDH, there are 6 elements.
* common/agent-opt.c: New.

(pinentry_mode_t): Factor out to shareddefs.h.
* agent/command.c (option_handler): Use parse_pinentry_mode.
This is not yet fully implemented. It will eventually allow to
support pinpad equipped readers which do not support variable length
pin lengths.
* agent/protect.c (parse_shadow_info): Add optional arg R_PINLEN and
parse pinlen info. Change all callers to pass NULL for it.
* agent/command.c: Include asshelp.h.
(cmd_pkdecrypt, cmd_genkey, cmd_preset_passphrase)
(pinentry_loopback): Use print_assuan_status for INQUIRE_MAXLEN.
This status message is used to inform the client of the maximum length
of an inquired passphrase and is used in pinentry-mode=loopback.
* agent/command.c (pinentry_loopback): Send the INQUIRE_MAXLEN status
message before doing the inquire.
When this mode is set an inquire will be sent to the client to retrieve
the passphrase. This adds a new inquire keyword "NEW_PASSPHRASE" that the
GENKEY and PASSWD commands use when generating a new key.

* command.c (cmd_import_key): Release key from failed import
before converting openpgp private key in the openpgp-private-key
case.
We better do this once and for all instead of cluttering all future
commits with diffs of trailing white spaces. In the majority of cases
blank or single lines are affected and thus this change won't disturb
a git blame too much. For future commits the pre-commit scripts
checks that this won't happen again.
