This code has seen only a very few manual tests. Encrypting always
uses a 64k chunks and decryption has not been tested with larger
chunks. Those small chunks make debugging much faster.
Tests can be done using:
gpg --rfc4880bis --pinentry-mode=loopback --passphrase abc \
--force-aead --aead-algo ocb --s2k-mode 0 --cipher AES \
-v -z 0 --status-fd 2 -c <INFILE >OUTFILE

--
The problem here was that future-default gives the primary and subkey
algorithm. However, when using future-default for adding a key, the
second part was always used which is for encryption. If the caller
now wanted to create a signing subkey using the future-default
parameters this did not worked.
gpg --batch --passphrase "" --quick-add-key FPR future-default encr
aready worked as did
gpg --batch --passphrase "" --quick-add-key FPR ed25519 sign
but
gpg --batch --passphrase "" --quick-add-key FPR future-default sign
does only work with this fix.

--
Originally the KBX code was written to allow standalone use. However
this required lot of ugliness like separate memory allocators and
such. It also precludes the use of some standard functions from
common due to their use of the common gnupg malloc functions.
Dropping all that makes things easier. Minor disadvantages: the kbx
call done for gpg will now use gcry malloc fucntions and not the
standard malloc functions. This might be a bit slower but removing
them even fixes a possible bug in keybox_tmp_names which is used in
gpg and uses gpg's xfree which is actually gcry_free.

* g10/keygen.c (keygen_set_std_prefs): when producing default internal
personal-digest-preferences, keep the same order. When publishing
external preferences, state preference for SHA512 first.
--
SHA-512 has a wider security margin than SHA-256. It is also slightly
faster on most of the architectures on which GnuPG runs today. New
keys should publish defaults that indicate we prefer the stronger,
more performant digest.
Specifically, this changes --default-preference-list from:
SHA256 SHA384 SHA512 SHA224
to:
SHA512 SHA384 SHA256 SHA224
This patch deliberately avoids touching --personal-digest-preferences
(which itself would affect the default of --digest-algo and
--cert-digest-algo), so that public-facing cleartext signatures and
identity certifications will continue to be made with SHA256 by
default.

This finalizes the feature to efficiently cache WKD checks. If a
standard WKD query returns no data, we queue a test to be run after
the end of the session (so that we do not delay the calling client).
This check tests whether the server responsible for the queried
address has WKD at all enabled. The test is done by checking whether
the "policy" file exists. We do not check the "submission-address"
file because that is not necessary for the web key operation. The
policy file is now required.
