When the callgraph function is enabled (-G), it may take a long time to
scan all the stack data and merge them accordingly.
This patch adds a new --max-stack option to perf-top to limit the depth
of callchain stack data to look at to reduce the time it takes for
perf-top to finish its processing. It reduces the amount of information
provided to the user in exchange for faster speed.
