perf top: Allow disabling/enabling events dynamicly
Now it is possible to press CTRL+z at anytime and that will disable the
events being monitored, essentially turning 'top' into 'report', with
pressing CTRL+z again making it enable the events again, returning to
the 'top' behaviour, i.e. dynamic + decaying of older samples.
One may want, for instance, play with:
-d, --delay <n> number of seconds to delay between refreshes
and:
-z, --zero zero history across updates
Plus CTRL+z to see only the events since last zeroing, etc.
