Description

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.
