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
fulfilled) our qualitybar is pretty bad and thus worse than none.

Note that in genkey() max_length is set to MAX_PASSPHRASE_LEN + 1
because in agent_askpin() decrements that value before conveying it to
the loopback.

Instead of using the old OpenPGP way of appending a hash of the
plaintext and encrypt that along with the plaintext, the new scheme
uses a proper authenticated encryption mode. See keyformat.txt for a
description. Libgcrypt 1.7 is required.
This mode is not yet enabled because there would be no way to return
to an older GnuPG version. To test the new scheme use
gpg-protect-tool:
./gpg-protect-tool -av -P abc -p --debug-use-ocb <plain.key >prot.key
./gpg-protect-tool -av -P abc -u <prot.key
Any key from the private key storage should work.

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.

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.

--
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).
Signed-off-by: Werner Koch <wk@gnupg.org>
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.
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.
