It has often been requested that the actually used IP of a keyservers
is shown in with gpg --recv-key and --search-key.  This is helpful if
the keyserver is actually a pool of keyservers.  This patch does this.

This slightly changes the semantics of most commands in that they

not make sense to create a trustdb if there is no need for it.

By modifying a keyserver or a DNS record to send a secret key, an
attacker could trick a user into signing using a different key and
user id.  The trust model should protect against such rogue keys but
we better make sure that secret keys are never received from remote
sources.

--

For ECC it seems to be better to show the name of the curve and not
just the size of the prime field.  The curve name does not anymore fit
into the "<size><letter>" descriptor (e.g. "2048R") and a fixed length
format does not work either.  Thus the new format uses

   "rsa2048"    - RSA with 2048 bit
   "elg1024"    - Elgamal with 1024 bit
   "ed25519"    - ECC using the curve Ed25519.
   "E_1.2.3.4"  - ECC using the unsupported curve with OID "1.2.3.4".

unless --legacy-list-mode is given.  In does not anymore line up
nicely in columns thus I expect further changes to this new format.

--

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.

This is a more general fix for the nested compression packet bug.  In

--

With the gpg-agent taking care of the secret keys, the user needs to
migrate existing keys from secring.gpg to the agent.  This and also
the standard import of secret keys required the user to unprotect the
secret keys first, so that gpg-agent was able to re-protected them
using its own scheme.  With many secret keys this is quite some
usability hurdle.  In particular if a passphrase is not instantly
available.

To make this migration smoother, this patch implements an unattended
key import/migration which delays the conversion to the gpg-agent
format until the key is actually used.  For example:

   gpg2 --batch --import mysecretkey.gpg

works without any user interaction due to the use of --batch.  Now if
a key is used (e.g. "gpg2 -su USERID_FROM_MYSECRETKEY foo"), gpg-agent
has to ask for the passphrase anyway, converts the key from the
openpgp format to the internal format, signs, re-encrypts the key and
tries to store it in the gpg-agent format to the disk.  The next time,
the internal format of the key is used.

This patch has only been tested with the old demo keys, more tests
with other protection formats and no protection are needed.

It is often time consuming to figure out whether still allocated

help for that register_mem_cleanup_func may now be used to cleanup
such memory.  The run time of the program will be longer; if that
turns out to be a problem we can change the code to only run in
debugging mode.
