The GPGME_ATTR_foo based functions are deprecated since 2003 and it is
time to remove them now.

The trustlist functions never worked:

  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 in 2003. It was anyway marked as experimental.

They even returned GPG_ERR_NOT_IMPLEMENTED since gpgme 1.14.0 (summer
2000) instead of failing with a incomprehensible error code.
