Moving diff related columns into diff command, because they are not used by any other command. Also moving the column entry functions under generic one with baseline as an exception.

* The kernel collects the number of events it couldn't send in a stretch and

* when possible sends this number in a PERF_RECORD_LOST event. The number of
|
|
* such "chunks" of lost events is stored in .nr_events[PERF_EVENT_LOST] while
|
|
* total_lost tells exactly how many events the kernel in fact lost, i.e. it is
|
|
* the sum of all struct lost_event.lost fields reported.
|
|
*
|
|
* The total_period is needed because by default auto-freq is used, so
|
|
* multipling nr_events[PERF_EVENT_SAMPLE] by a frequency isn't possible to get
|
|
* the total number of low level events, it is necessary to to sum all struct
|
|
* sample_event.period and stash the result in total_period.
