This new feature can be used to avoid the need for a key lookup and
thus several extra calls to the backend.
Note that run-test uses a semicolon as delimiter because that make
testing the feature on the command line much easier.

Manual testing of that wrap/unwrap feature can be done this way:
./run-encrypt --verbose --key Alice /etc/motd > x
./run-decrypt --verbose --unwrap x > y
./run-encrypt --verbose --key Bob --wrap y > z
1. The message was first encrypted to Alice.
2. Alice decrypts the message receiving a valid OpenPGP message.
3. Alice encrypt that message to Bob
This will also work with encrypted and signed messages; the signature
will be kept intact during re-encryption. Requires GnuPG 2.1.12.

It would be nice to also selectively hide recipients (that is gpg
--hidden-recipient) but our API does not ye allow this because it is
based on key objects. A possible way to implement that would be a API
to set processing flags into a key but this is complicated due to the
reference counting and thus the possibility that a key object is used
by different context.
