perf report: Allow limiting the number of entries to print in callchains
Works by adding a third parameter to the '-g' argument, after the graph
type and minimum percentage, for example:
[root@doppio linux-2.6-tip]# perf report -g fractal,0.5,2
Will show only the first two symbols where at least 0.5% of the samples
took place.
All the other symbols that don't fall outside these constraints will be
put together in the last entry, prefixed with "[...]" and the total
percentage for them.
