Given that a user can anyway change that options in the gpg-agent.conf
file and that gpg needs to be invoked with --pinentry-mode=loopback
the former default does not make much sense - in that option is useful
at all. There was a discussion of this topic on gnupg-devel in April
without a clear result. So we try this new default and just in case
real problems are found for the majority of installations, we can
revert that. The new default is also aligned with GnuPG's policy to
make its use easier and only require users with very high security
standards to tweak certain options (those users have anyway modeled
their threat model and configured their software according to this).

We also put the key information after the message and not between the

The most recent message was verified 3 days, 13 hours ago.
(key: 8061 5870 F5BA D690 3336 [...] 1E42 B367, policy: auto)
This also makes the key info a separate translatable string.
Further a compact version of the fingerprint (hex w/o spaces) is
printed in some messages.

The Web Key Directory is an experimental feature to retrieve a key via
https. It is similar to OpenPGP DANE but also uses an encryption to
reveal less information about a key lookup.
For example the URI to lookup the key for Joe.Doe@Example.ORG is:
https://example.org/.well-known/openpgpkey/
hu/example.org/iy9q119eutrkn8s1mk4r39qejnbu3n5q
(line has been wrapped for rendering purposes). The hash is a
z-Base-32 encoded SHA-1 hash of the mail address' local-part. The
address wk@gnupg.org can be used for testing.

We should have a macro so that we do not need to define a wrapper
function like my_error_from_syserror in files where it is needed. I
am not sure about a proper name, "my_" seems to be the easiest
replacement. Note that the global DEFAULT_ERRSOURCE is relatively new
to replace the need to convey the error source in function calls; we
want that function from common/ return the error source of the main
binary.
We require that a key is ASCII and thus we better use ascii_strcasecmp
to avoid problems with strange locales.

GnuPG 2.3+ will use a new format to store private keys that is both
more flexible and easier to read and edit by human beings. The new
format stores name,value-pairs using the common mail and http header
convention.
This patch adds the parser and support code and prepares GnuPG 2.1 for
the new format.

The buggy code included an extra closing parenthesis before

hashing only differs that it does no include the protected part.

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.

Specifically exporting RSA keys of length 1024 failed, as the encoded
