api: Add new function gpgme_set_ctx_flag.

* src/gpgme.h.in (gpgme_set_ctx_flag): New prototype.
* src/gpgme.c (gpgme_set_ctx_flag): New.
* src/gpgme.def, src/libgpgme.vers: Add new function.
* src/context.h (struct gpgme_context): Add FULL_STATUS.
* src/decrypt.c (_gpgme_decrypt_status_handler): Do not call the
  status callback if FULL_STATUS is set.
* src/genkey.c (genkey_status_handler): Ditto.
* src/passphrase.c (_gpgme_passphrase_status_handler): Ditto.
* src/sign.c (_gpgme_sign_status_handler): Ditto.

* src/engine-backend.h (struct engine_ops): Add SET_STATUS_CB and add
adjust all definitions of that variable.
* src/engine.c (_gpgme_engine_set_status_cb): New.
* src/op-support.c (_gpgme_op_reset): Call this function.

* src/engine-gpg.c (struct engine_gpg): Add fields MON_CB and
MON_CB_VALUE.
(gpg_set_status_cb): New.
(_gpgme_engine_ops_gpg): Register that function.
(read_status): Call the monitor callback.

* src/engine-gpgsm.c (struct engine_gpgsm): Add fields MON_CB and
MON_CB_VALUE.
(_gpgme_engine_ops_gpgsm): Register that function.
(gpgsm_assuan_simple_command): Change first arg to be an engine
context and adjust call callers.  Call the monitor callback.

* src/engine-uiserver.c (struct engine_uiserver): Add fields MON_CB
and MON_CB_VALUE.
(_gpgme_engine_ops_uiserver): Register that function.
(uiserver_assuan_simple_command): Change first arg to be an engine
context and adjust call callers.  Call the monitor callback.

* tests/run-verify.c (status_cb): New.
(print_result): Print algo names.
(main): Add option --status.
--

This new feature is mainly intended for bug tracking.  Having access
to the raw status lines might also be useful for applications, though.
