Code that checks dstate is unaware of SystemTap and LTTng UST dstate, so
the following trace event will not fire when solely enabled by SystemTap
or LTTng UST:
if (trace_event_get_state(TRACE_MY_EVENT)) {
str = g_strdup_printf("Expensive string to generate ...",
...);
trace_my_event(str);
g_free(str);
}
Add trace_event_get_state_backends() to fetch backend dstate. Those
backends that use QEMU dstate fetch it as part of
generate_h_backend_dstate().
Update existing trace_event_get_state() callers to use
trace_event_get_state_backends() instead.
