tracing: Add needs_rec flag to event triggers Add a new needs_rec flag for triggers that require unconditional access to trace records in order to function. Normally a trigger requires access to the contents of a trace record only if it has a filter associated with it (since filters need the contents of a record in order to make a filtering decision). Some types of triggers, such as 'hist' triggers, require access to trace record contents independent of the presence of filters, so add a new flag for those triggers.
