[Qemu-devel] [PATCH v2 3/6] trace: remove some now unused functions

["Daniel P. Berrange" <berrange@redhat.com>]

The trace_event_count, trace_event_id and
trace_event_pattern methods are no longer required
now that everything is using the iterator APIs

The trace_event_set_state and trace_event_set_vcpu_state
macros were also unused.
