* src/keylist.c (gpgme_op_keylist_from_data_start): New.
* src/engine-backend.h (engine_ops): Add field 'keylist_data'.  Change
all engines to pass NULL for it.
* src/engine.c (_gpgme_engine_op_keylist_data): New.
* src/engine-gpg.c (gpg_keylist_data): New.
(_gpgme_engine_ops_gpg): Register gpg_keylist_data.
