gpg: Provide better diagnostic for replaced card keys.
* agent/divert-scd.c (divert_pksign): Add arg 'grip'.  Replace OPENPGP
key reference to keygrips.
(divert_pkdecrypt): Ditto.
* agent/protect.c (parse_shadow_info): Trim spaces.
* agent/pkdecrypt.c (agent_pkdecrypt): Pass the keygrip.
* agent/pksign.c (agent_pksign_do): Ditto.

* g10/mainproc.c (print_pkenc_list): Print extra info for an invalid
id error.
* g10/sign.c (do_sign): Ditto.
--

Using the keygrip instead of the identifier works on OpenPGP cards and
thus we use that to make sure that we are working on the right card.
For other cards we better don't do that to avoid regressions.  Those
other cards are also usually provided and do not allow to
self-generate the keys.

Note that old versions of the code (gpg 1.4) used the fingerprint as
additional check but that was eventually removed and now that we use
the keygrip all over the place, it is best to use this to identify a
key.

w32: Support Unicode also for config files etc.
* common/sysutils.c (gnupg_fopen) [W32]: Use _wfopen if needed.   Use
new function in most places where fopen is used.
--

The config files in 2.2 are still read using fopen - we need to change
this to allow Unicode directory names.  There is also one case where
files are written using the old fopen.  The new option parser in 2.3
does not have this problem but at some places fopen is also still used.

The concept of a passphrase quality indicator is anyway questionable
because user are smart enough to trick them out and they also tend to
limit the actually used entropy.

Except for the red/green switching (to show whether constraints are

This is only a problem on big-endian systems where size_t is not the

There may well be other failures with %b on those platforms in the
codebase, and it probably needs an audit.

Once you have a key in private-keys-v1.d/$KEYGRIP.key with a comment
or a uri of reasonable length associated with it, this fix can be
tested with:

   gpg-agent --server <<<"READKEY $KEYGRIP"

On the failing platforms, the printed comment will be of length 0.

213379debe agent: Fix error code check from npth_mutex_init.
* agent/call-pinentry.c (initialize_module_call_pinentry): It's an
error when npth_mutex_init returns non-zero.

--

Cherry-pick from master commit of:
	adce73b86fd49d5bbb8884231a26cc7533d400e2

Actually, initialize_module_call_pinentry is only called once from
main.  So, this bug had no harm and having the static variable
INITIALIZED is not needed.

agent: Add DBUS_SESSION_BUS_ADDRESS et al. to the startup list.
* agent/gpg-agent.c (agent_copy_startup_env): Replace explicit list
with the standard list.
--

Although the function agent_copy_startup_env is newer than
session_env_list_stdenvnames the latter was not used.  When
DBUS_SESSION_BUS_ADDRESS was added to the latter it was forgotten to
add it to the former as well.  Having all stdnames here seems to be
the Right Thing (tm) to do.

It is sometimes helpful to be able to inspect certain envvars in a
running agent.  For example "http_proxy".

381c46818f agent: unknown flags on ssh signing requests cause an error.
* agent/command-ssh.c (ssh_handler_sign_request): if a flag is passed
during an signature request that we do not know how to apply, return
GPG_ERR_UNKNOWN_OPTION.

https://tools.ietf.org/html/draft-miller-ssh-agent-02#section-4.5 says:

    If the agent does not support the requested flags, or is otherwise
    unable or unwilling to generate the signature (e.g. because it
    doesn't have the specified key, or the user refused confirmation of a
    constrained key), it must reply with a SSH_AGENT_FAILURE message.
