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.)

This patch adds support for a to be proposed OpenPGP ferature:
Introduce the Key Block subpacket to align OpenPGP with CMS.
This new subpacket may be used similar to the CertificateSet of
CMS (RFC-5652) and thus allows to start encrypted communication
after having received a signed message. In practice a stripped down
version of the key should be including having only the key material
and the self-signatures which are really useful and shall be used by
the recipient to reply encrypted.
#### Key Block
(1 octet with value 0, N octets of key data)
This subpacket MAY be used to convey key data along with a signature
of class 0x00, 0x01, or 0x02. It MUST contain the key used to create
the signature; either as the primary key or as a subkey. The key
SHOULD contain a primary or subkey capable of encryption and the
entire key must be a valid OpenPGP key including at least one User ID
packet and the corresponding self-signatures.
Implementations MUST ignore this subpacket if the first octet does not
have a value of zero or if the key data does not represent a valid
transferable public key.

This fixes a potential overflow if LFs are passed to the status

because neither the truncating in libassuan or our escaping is not the
Right Thing. In any case the functions need to be more robust and
comply to the promised interface. Thus the code has been factored out
to a helper function and N has been bumped up correctly and checked in
all cases.
For some uses this changes the behaviour in the error case (i.e. CR or
LF passed): It will now always be C-escaped and not passed to
libassuan which would truncate the line at the first LF.

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.
