core: Deprecate the non-working trustlist functions.
* src/gpgme.h.in: Clarify that the trustlist function should not be used. * src/engine.c (_gpgme_engine_op_trustlist): Always return an error. * src/engine-backend.h (struct engine_ops): Remove trustlist member. * src/engine-gpg.c (gpg_trustlist): Remove. (struct engine_ops): Remove that member. Also in all other engines. * tests/gpg/t-trustlist.c: Remove. * lang/python/tests/t-trustlist.py: Remove.
This never worked in reality because the required feature has been
removed from GnuPG version 1.3.2 soon after introduction of this
feature in gpgme - 17 years ago. It was anyway marked as
experimental. We keep the API and ABI, though.
