* agent/call-pinentry.c (setup_qualitybar): Add arg ctrl anc change

* agent/findkey.c (try_unprotect_cb): Add local var ctrl.
* agent/genkey.c (check_passphrase_constraints): Replace xtryasprintf
by xtrystrdup to avoid gcc warning.  Unfortinately this changes the
string.
(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
browser session.  AS of now it only displays a different "Note: in
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.

The idea with this change is that under Windows we can install a

version may then later install pinentry-gtk etc which would then
automatically be used.

Unfortunately installing another pinentry from a different package
would clobber the GnuPG core directory which is not nice.  To fix that
we would need to agree on standard installation directories for GUIs
to also look there.

A remote connection is and should not be able to setup the local

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.

gnulib has always been a cause of trouble in GnuPG because we used
only a very few functions and the complex include machinery of gnulib
is quite complex and the cause for many build problems for example on
OS X.  This is not gnulib's fault but due to our limited use of gnulib
and that we only rarely update the gnulib code to avoid regressions.

In part two we will address the functions

 mkdtemp
 setenv
 unsetenv
 strpbrk

which may bot be implemented on all platforms.  They are not required
on a libc based system.

If we need to confirm a passphrase entry (e.g. for new passphrase) we

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).

The key transfer protocol between gpg and gpg-agent uses gcrypt

algorithm.  We need to known that because Libgcrypt requires the
"eddsa" flag with the curve "Ed25519" to actually use the Ed25519
signature specification.

The last fix is for correctness; the first case won't be used anyway.

it is at some places quite baroque and more complicated than needed.

The gpg server mode is not actual working and thus we can avoid the
warnings by explicitly disabling the mode.  We keep it working under
Unix, though.

90688b29f3 agent: Fix UPDATESTARTUPTTY for ssh.
* agent/command-ssh.c (setup_ssh_env): Fix env setting.
--

gniibe reported this to gnupg-devel on 2012-07-04:

  [...]
  (2) UPDATESTARTUPTTY doesn't work to switch TTY for pinentry for
      SSH.

  [...]

  Current implementation:

      In the function start_command_handler_ssh, the logic puts
      priority on ctrl->session_env which is initialized by
      agent_init_default_ctrl.  There are always GPG_TTY and TERM
      defined, because lines around 968 in gpg-agent.c, it says:

  	/* Make sure that we have a default ttyname. */

      While UPDATESTARTUPTTY updates opt.startup_env, it doesn't
      affect at all.

  Here is a patch to point the issue.  Tested and works for me.

These changes have been in effect for the Gpg4win Windows version
since 2011-01-24 and thus first released with Gpg4win 2.1.0.  Given
the current state of PKIX it does not make any sense to lure the Unix
user into false security by making it harder to trust self-signed or
CAcert certificates.

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.

May thanks to gniibe who implemented a proxy in Python to test the
putty/gpg-agent communication.

This is for now a theoretical fix because there is no ssh client yet
which uses the GnuPG style IPC.  OpenSSL for Cygwin uses only a quite
similar one.  gniibe suggested to implement that IPC style in
Libassuan so that a Cygwin version of OpenSSL may be used with GnuPG.
