Although all of the trace event triggers can be used in instances, most
of them affect the top-level instance even when triggered from within an
instance. This patch set makes them affect the instance in which the
trigger occurred. The enable_event & disable_event triggers already work
within the correct instance, so these are unchanged.

The same problem also exists with the function probe triggers, but they
will be fixed in a later patch set.

Patch 1 is preparatory.
Patch 2 fixes the stacktrace event trigger
Patch 3 fixes the traceon & traceoff event triggers
Patch 4 fixes the snapshot event trigger
Patch 5 Makes related warning messages also go to the correct instance
