core: Support writing the sign/encrypt output directly to a file
* src/engine-gpg.c (gpg_encrypt): Pass output file name to gpg if output
has file name set.
(gpg_encrypt_sign): Ditto.
(gpg_sign): Ditto.

* tests/run-encrypt.c (show_usage): New option --output.
(main): Parse new option. Set file name on output if --output is given.
Do not print output if --output is given.
* tests/run-sign.c (show_usage): New option --output.
(main): Parse new option. Set file name on output if --output is given.
Do not print output if --output is given.

This change makes it possible to tell gpg (and gpgtar) to write the
output (i.e. the signed/encrypted data or the signature or the created
archive) directly to a file with given file name instead of piping
the output back to gpgme.

core: Support usage of gpgtar for creating an encrypted signed archive
* src/engine-gpg.c (gpg_encrypt_sign): Set use_gpgtar engine flag if
GPGME_ENCRYPT_ARCHIVE mode is set. Check for new enough gpg. Use
add_gpg_arg_with_value for gpg-only options with a value and
add_gpg_arg for gpg-only options without a value. Set extra options for
gpgtar and pass input data to stdin when using gpgtar.

* tests/run-encrypt.c (print_result): Rename to print_encrypt_result.
Print header.
(print_sign_result): New.
(show_usage): New option --sign.
(main): Parse new option. Sign and encrypt --sign is given.
Print results of signing additionally to results of encryption.
--

With this change the gpgme_op_encrypt_sign* functions get support for
creating an encrypted and signed archive from files and/or directories
passed as NUL-separated list in the "plain" data with gpgtar.

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.

* tests/run-decrypt.c (main): New option --unwrap.

--

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.
