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.

We better do this once and for all instead of cluttering all future
commits with diffs of trailing white spaces. In the majority of cases
blank or single lines are affected and thus this change won't disturb
a git blame too much. For future commits the pre-commit scripts
checks that this won't happen again.
