* agent/command-ssh.c (SPEC_FLAG_WITH_CERT): New.
(ssh_key_types): Add OpenSSH cert types.

(ssh_receive_mpint_list): New arg CERT and use it.
(ssh_receive_key): Read certificate into an estream object and modify
parser to make use of that object.
--
This is a first step to support certificate via the agent. The only
effect of this change is the removal of an error message parsing the
certificate. Note that ssh-add sends the private key anyway first and
only then follows with the certificate+private key.
What we need to implement next is a way to store the certificate in
the agent and return it on request.

* agent/pksign.c (agent_pksign_do): Use public key smartcard.
--
Since gcry_pk_verify can't handle shadowed private key, public
key SEXP should be prepared for smartcard.
* agent/genkey.c (agent_ask_new_passphrase): Use a separate malloc for
PI2. Check return value of the malloc function.
* agent/command-ssh.c (ssh_identity_register): Use a separate malloc
for PI2. Wipe PI2.
--
For whatever stupid reasons I once allocated only one memory area and
split that into PI and PI2. This is actually a common pattern with
malloc but here we used a made up object size and do not take the
extra alignment required into account. One of these not yet hit by
a (sig)bus PC/VAX hacker bugs.
Instead of trying to fix the alignment, it is better to use a second
calloc for the second struct.

* g10/sign.c (do_sign): Let verify signature by gpg-agent.
* agent/pksign.c (agent_pksign_do): Call gcry_pk_verify for RSA.
--
RSA signature verification should be done to prevent attacks against
RSA CRT implementations and not to return invalid signature to
adversary. Newer libgcrypt does so. For older libgcrypt and
smartcards, gpg-agent does signature verification.
* agent/cvt-openpgp.c (convert_from_openpgp_main): Only encrypted
parameters are stored as opaque.
(apply_protection): ARRAY members are all normal, non-opaque MPI.
(extract_private_key): Get public key as normal, non-opaque MPI.
Remove support of ECC key with '(flags param)'.
Remove support of "ecdsa" and "ecdh" keys of our experiment.
* agent/command.c (cmd_get_passphrase): Don't repeat passphrase for
pinentry loopback mode.

pinentry mode is loopback.

--
When libgcrypt has Curve25519, GnuPG now supports Curve25519.
* common/util.h: Provide replacement for GPGRT_ATTR_ macros when using
libgpg-error < 1.20.
* common/mischelp.h: Ditto.
* common/types.h: Ditto.
--
Given that libgpg-error is a dependency of all GnuPG related libraries
it is better to define such macros at only one place instead of having
similar macros at a lot of places. For now we need repalcement
macros, though.
* agent/gpg-agent.c (main): Unset INSIDE_EMACS envvar.
--
The variable is set only temporarily when gpg is called from Emacs,
keeping it during the session makes no sense.

(agent_ask_new_passphrase): Cleanup the use of initial_errtext.
--
Static strings in gpg-agent need to be translated according to the
locale set by the caller. This is required so that a gpg-agent can be
started in one locale and a gpg can be run in another. If we don't do
this the static strings (prompt, buttons) are not or in the wrong
locale translated while dynamic strings (e.g. key description) uses
the locale of gpg.
This is only the first part of the change the actual local switching
still needs to be implemented.

This is very similar to --extra-socket but intended to be used by a web

the Pinentry than --extra-socket but it may eventually be tweaked for
the use by browser extensions making use of gpg-agent.
It is marked experimental and and thus may be removed in later
versions.
To better support the different "client classes", it would be useful
to add corresponsing cache classes so that each class has its own
cache.
