This patch add support of ECC key with a curve name and flags. Since

--
A remote connection is and should not be able to setup the local
session environment. However, unless --keep-display is used we would
be left without an environment and thus pinentry can't be used. The
fix is the same as used for ssh-agent connection: We use the default
environment as used at the startup of the agent.

The requirement of using --card-status on the first use of card on a

promising either.

If we need to confirm a passphrase entry (e.g. for new passphrase) we
set a flag into the pinentry info block. The we try to use the new
pinentry command SETREPEATERROR; if that fails, we continue as usual.
If that succeeds we ask the pinentry to show the repeat (confirmation)
prompt and on successful return we set another flag in the pinentry
info block so that the caller can skip its own confirmation check. A
new status line from the pinentry indicates that the feature is
actually supported (it may not be supported on certain systems for
example when using the ncurses backend).

This patch adds two features:
1. The key for the last passphrase successfully used for unprotecting
a key is stored away. On a cache miss the stored away passphrase is
tried as well. This helps for the common GPG use case of having a
signing and encryption (sub)key with the same passphrase. See the
code for more comments.
2. The now auto-generated revocation certificate does not anymore
popup a passphrase prompt. Thus for standard key generation the
passphrase needs to be given only once (well, two with the
confirmation).

This patch enables support for Putty. It has been tested with Putty
0.62 using an Unix created ssh key copied to the private-keys-v1.d
directory on Windows and with a manually crafted sshcontrol file. It
also works with a smartcard key.

--
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.

(pinentry_mode_t): Factor out to shareddefs.h.

This is not yet fully implemented. It will eventually allow to

* agent/protect.c (parse_shadow_info): Add optional arg R_PINLEN and
parse pinlen info. Change all callers to pass NULL for it.
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.
The protection used in the exported key used a different iteration
count than given in the S2K field. Thus all OpenPGP keys exported
from GnuPG 2.1-beta can't be imported again. Given that the actual
secret key material is kept in private-keys-v1.d/ the can be
re-exported with this fixed version.
This was a regression in 2.1 introduced due to having the agent do the
signing in contrast to the old "SCD PKSIGN" command which accesses the
scdaemon directly and passed the hash algorithm. The hash algorithm
is used by app-openpgp.c only for a sanity check.
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.
