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.

This feature can be used to return the session key for just a part of
a file. For example to downloading just the first 32k of a huge file,
decrypting that incomplete part and while ignoring all the errors
break out the session key. The session key may then be used on the
server to decrypt the entire file without the need to have the private
key on the server.

* common/status.h (STATUS_RSA_OR_IDEA): Remove. Do not emit this

--
To keep the number of actually used algorithms low, we want to support
IDEA only in a basically read-only way (unless --pgp2 is used during
key generation). It does not make sense to suggest the use of this
old 64 bit blocksize algorithm. However, there is old data available
where it might be helpful to have IDEA available.
This works by specifying the keygrip instead of an algorithm (section
number 13) and requires that the option -expert has been used. It
will be easy to extend this to the primary 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.
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.
