It is now possible to print a DANE record given a a file with a key
without importing the key first:
gpg --export-options export-dane \
--import-options import-export \
--import-filter keep-uid='mbox =~ alpha' \
--import FILE_WITH_KEY
Using the filter we only print a user id with the substring "alpha" in
the addr-spec.

This patch separates Libgcrypt and OpenPGP public key algorithms ids
and in most cases completely removes the Libgcrypt ones. This is
useful because for Libgcrypt we specify the algorithm in the
S-expressions and the public key ids are not anymore needed.
This patch also adds some support for PUBKEY_ALGO_EDDSA which will
eventually be used instead of merging EdDSA with ECDSA. As of now an
experimental algorithm id is used but the plan is to write an I-D so
that we can get a new id from the IETF. Note that EdDSA (Ed25519)
does not yet work and that more changes are required.
The ECC support is still broken right now. Needs to be fixed.

The asymmetric quotes used by GNU in the past (`...') don't render
nicely on modern systems. We now use two \x27 characters ('...').
The proper solution would be to use the correct Unicode symmetric
quotes here. However this has the disadvantage that the system
requires Unicode support. We don't want that today. If Unicode is
available a generated po file can be used to output proper quotes. A
simple sed script like the one used for en@quote is sufficient to
change them.
The changes have been done by applying
sed -i "s/\`\([^'\`]*\)'/'\1'/g"
to most files and fixing obvious problems by hand. The msgid strings in
the po files were fixed with a similar command.
Returning -1 as an error code is not very clean given that gpg error
has more descriptive error codes. Thus we now return
GPG_ERR_NOT_FOUND for all search operations and adjusted all callers.
The protection used in the exported key used a different iteration
count than given in the S2K field. Thus all OpenPGP keys exported
from GnuPG 2.1-beta can't be imported again. Given that the actual
secret key material is kept in private-keys-v1.d/ the can be
re-exported with this fixed version.
Since 2009-12-08 gpg was not able to find email addresses indicated
by a leading '<'. This happened when I merged the user id
classification code of gpgsm and gpg.
Without Libgcrypt 1.5 is was not possible to use ECC keys. ECC is
major new feature and thus it does not make sense to allow building
with an older Libgcrypt without supporting ECC.
Also fixed a few missing prototypes.
Import and export of secret keys does now work. Encryption has been
fixed to be compatible with the sample messages.
This version tests for new Libgcrypt function and thus needs to be
build with a new Libgcrypt installed.
Changed order of some conditional to make to put the special case into
the true branch. Indentation changes. Minor other changes to make the
ECC code more similar to the rest of our code.
It builds but many sefltests still fail. Need to fix that before
using it with an ECDH enabled libgcrypt.
