--

This patch allows to decrypt data encrypted using the new AEAD
mechanism as specified in rfc4880bis.  Although preferences are used
to enable this new mode, it is useful to have at least a decryption
option in case a user switches between GnuPG 2.2 and newer versions.

The new AEAD mechanism is much faster than the current CFB+MDC and
thus 2.2 will allow faster decryption of symmetric only decryption.

This patch is based on the current master (2.3) code base and includes
a few other patches.  In particular
commit 44be675b75
(gpg: More check for symmetric key encryption.)
is included.
