	* gpgme.c (gpgme_set_io_cbs): Deal with CTX being NULL.

	* gpgme.c (_gpgme_op_event_cb_user): New function.
	* op-support.c (_gpgme_op_reset): Support a new mode of operation
	for private or user event loop.  Use new user event callback
	wrapper.
	* trustlist.c (gpgme_op_trustlist_start): Use this new mode.
	* keylist.c (gpgme_op_keylist_start): Likewise.

	* rungpg.c (_gpgme_gpg_io_event): New function.
	* rungpg.h (_gpgme_gpg_io_event): New prototype.
	* engine-gpgsm.c (_gpgme_gpg_io_event): New function.
	* engine-gpgsm.h (_gpgme_gpgsm_io_event): New prototype.
	* engine.c (_gpgme_engine_io_event): New function.
	* engine.h (_gpgme_engine_io_event): New prototype.
	* keylist.c (finish_key): Call _gpgme_engine_io_event, and move
	the real work for the default IO callback routines to ...
	(_gpgme_op_keylist_event_cb): ... here.  New function.
	* trustlist.c (trustlist_colon_handler): Signal
	GPGME_EVENT_NEXT_TRUSTITEM.  Move queue manipulation to ...
	(_gpgme_op_trustlist_event_cb): ... here.  New function.
	* gpgme.c (_gpgme_op_event_cb): Call _gpgme_op_keylist_event_cb
	and _gpgme_op_trustlist_event_cb when appropriate.
	* ops.h (_gpgme_op_keylist_event_cb): New prototype.
	(_gpgme_op_trustlist_event_cb): Likewise.
	* op-support.c (_gpgme_op_reset): Add comment why we don't use the
	user provided event handler directly.
	* gpgme.h (GpgmeRegisterIOCb): Return GpgmeError value, and TAG in
	a pointer argument.
	* wait.c (_gpgme_add_io_cb): Likewise.
	* wait.h (_gpgme_add_io_cb): Likewise for prototype.
	* rungpg.c (_gpgme_gpg_add_io_cb): Call IO_CBS->add with new
	argument.  Fix up error handling.
	* engine-gpgsm.c (_gpgme_gpgsm_add_io_cb): Call IO_CBS->add with
	new argument, fix up error handling.
