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.
