* src/gpgme.c: Include mbox-util.h.
(gpgme_release): Free SENDER.
(gpgme_set_sender): New.
(gpgme_get_sender): New.
* src/gpgme.def, src/libgpgme.vers: Add new functions.

* src/engine-gpg.c (append_args_from_sender): New.
(gpg_encrypt_sign, gpg_sign): Call append_args_from_sender.
(gpg_verify): Add arg CTX.  Call append_args_from_sender/
* src/engine-gpgsm.c (gpgsm_verify): Add dummy arg CTX.
* src/engine-uiserver.c (uiserver_verify): Ditto.
* src/engine.c (_gpgme_engine_op_verify): Add arg CTX.
* src/verify.c (verify_start): Pass CTX to engine function.

* tests/gpg/t-verify.c (main): Add some checks for new functions.
* tests/run-sign.c (main): Add option --sender.
