Remove trust_item stuff to make it build with gpgme 2.x
* src/gpacontext.h (struct _GpaContextClass): Remove next_trust_item. * src/gpacontext.c (NEXT_TRUST_ITEM): Remove (gpa_context_class_init): Remove assignment. (gpa_context_event_cb): Remove handler. (gpa_context_next_trust_item): Remove.
Note that the trust item feature worked only for a very short period
in 2003.
