trace_processor: Expose deltas of ftrace stats In presence of overlapping traces the current practice of alerting on overrun_end > 0 is incorrect instead, we should consider overrun_end-overrun_begin > 0. Expose all the stats where deltas are sensible while we're at it and finally also guard against new ftrace stats notifications (e.g. in the middle of the trace, on a timer, etc).
