gpg: Do not abort on certain invalid packets.
* g10/build-packet.c (write_fake_data): Check for non-opaque data.
* g10/seskey.c (do_encode_md): Return NULL instead of abort.
--

The first may happen if the usage flags of an algorithm do not match
the allowed usage.  When writing a backsig this would lead to a
log_bug in libgcrypt due to the use of a regular MPI as opaque data.

The second may happen with all kind of invalid data.  It is easy to
avoid an abort, though.

gpg: Speed up key listing in Tofu mode.
* g10/tofu.c (get_trust): Add arg PK.  Uses this instead of a an extra
lookup of the public key by fingerrpint.
(tofu_register): Pass PK to get_trust.

*g10/tofu.c (tofu_register): Remove unused FINGERPRINT_PP.
--

With my test keybox I see a speedup of 10 times (33s to 3.1s).  The
reason for this was the extra key lookup which I hacked in at some
point to make the extraction of a keyid correct also for non v4 keys.
However our caller already has the public key and thus can easily pass
it to get_trust along with the fingerprint.

This fixes two bugs: The first was a typo which led to us comparing A

this can't be asserted: Two signature may have different algorithms;
they won't verify but after all it is about corrupted signatures.

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

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.

agent_open() is only defined statically in common/simple-pw-query.c,
it is neither used nor referenced anywhere else.  agent_close doesn't
exist anywhere.  The removal of these declarations removes an
unecessary inclusion of libassuan.h.

migrate.c was relying on keydb.h -> libassuan.h -> unistd.h for the
